50 Animals of The Sonoran Desert (with Pictures)

With an area of almost 100.000 square miles, The Sonoran Desert is home to a wide range of animals.

Unhospitable at first glance, this desert houses birds, rodents, spiders, wolves, and even fish.

This large desert spreads from The US (California to Arizona) to Mexico (Sonora, Baja California, and California Sur).

Here are some of the most common species likely to be encountered here.

Invertebrates of the Sonoran Desert

1. Western Desert Tarantula

A species mostly specific to The Sonoran, The Western Desert Tarantula (Aphonopelma chalcodes) shows the ground colors of the desert plus a venomous nature.

Western Desert Tarantula

Tarantulas of the species grow to a size of up to 5 inches, with shorter individuals measuring 3-4 inches.

Apart from size differences, males and females are also differently colored.

Dominated by brown nuances, females feature a brighter carapace.

Males have a brown and copper color but they feature black legs and are easier to spot as they don’t match their color to their habitats as much as females.

Western Desert Tarantulas are venomous. This venom isn’t dangerous to humans but their bites are painful, usually with a sting-like level of pain.

2. Desert Whitetail

Desert Whitetail

Seeps, streams, and water accumulation in the desert are home to The Desert Whitetail (Plathemis subornata).

A species that depends on water, The Desert Whitetail is one of the most unlikely species of this arid climate.

It’s young, called naiads, and even depends on water to mature.

This fly can be seen up until September in The Sonoran as well as outside of the desert.

A bright blue nuance and transparent wings are some of its main physical traits.

Desert Whitetail are seen next to water where they lay eggs and when they can find their next meal which is often a type of mosquito.

3. Desert Stink Beetles

Desert Stink Beetles

A species of the Sonoran and Western North America, Desert Stink Beetles (genus Eleodes) are a species named after they release defensive chemicals.

Some types of bugs in the desert are considered beneficial species through their diet.

This is the situation of Desert Stink Beetles, types of beetles that eat dead plants and dead animal remains.

With a small role in the ecosystem, these types of bugs may alternatively look towards living plants as well.

These bugs are mostly known for spraying a deterring small from their rear end to keep their predators away.

To do this, the bugs raise their rear end pointing it towards the perceived danger.

4. Desert Recluse

Desert Recluse

Desert Recluses (Loxosceles deserta) are known for their potent bite. These large spiders feature tan and brown nuances and are found in The Sonoran Desert.

These spiders may also feed on dead insects, similar to Desert Stink Beetles, but they prefer living insects.

While they live far away from humans, the spiders can still bite, often with visible and painful effects.

Necrosis is among the worse reactions to the bites of these spiders.

In some cases, the necrotic skin in the area of the bite goes away within days. In more severe cases, it takes weeks for the skin to heal following its venomous bite.

It’s always recommended to visit a doctor following the bite of The Desert Recluse.

5. Sonoran Desert Centipede

Sonoran Desert Centipede

One of the most enigmatic species of the desert is The Sonoran Desert Centipede (Scolopendra polymorpha).

While it seems absent from most areas, this is a centipede that lives under rocks and shrubs, in areas of high vegetation.

A carnivorous species, The Sonoran Desert Centipede has a varied diet which includes insects and even lizards.

Growing to a size of up to 8 inches, these centipedes can eat some of the largest insects in the desert.

They are also prey for local wildlife.

Much of the lives of these centipedes are pend hiding from the sun. Even in difficult conditions, these centipedes can survive for years.

6. Western Horse Lubber Grasshopper

Western Horse Lubber Grasshopper

Western Horse Lubber Grasshoppers (Taeniopoda eques) have a black and yellow color in The Sonoran Desert.

This is a species known for its high adaptability to desert life.

For example, the bugs perch on the small desert plants during the day so that they are less visible and easier to pick on by predators.

At night, they begin roaming around for food.

Their dietary preferences are vast, and often misunderstood. From plants to spider webs and cocoons, they can eat almost anything.

The bugs are also known for eating the excrement of a few other species.

Mostly spotted individually, Western Horse Lubber Grasshoppers spend the first weeks of their life living and feeding together.

7. Maricopa Harvester Ant

Maricopa Harvester Ant

Maricopa Harvester Ants (Pogonomyrmex maricopa) are among the most numerous insects in The Sonoran Desert.

They are also venomous and can bite. The result of the bite is high pain and even long-lasting pain.

As with most ants here, The Maricopa Harvester Ant is highly resourceful when it comes to desert living.

These ants build large ant mounds but these are different than other ant mounds in other areas such as grassland.

The high wind of the desert can easily break away any ant mount.

Maricpa Harvester ants dig deep for calcium carbonate which they use to line the outer layer of the nest.

The result is a type of hardened surface that resists high wind and heat over time.

8. Marine Blue

Marine Blue

A dark species of the desert, The Marine Blue butterfly (Leptotes marina) is also known as The Striped Blue Butterfly.

This is one of the darker species of The Sonoran, often being compared to moths.

Its dark brown wings show black and dark blue nuances while its body is body dark blue to black.

The coloring of the ventral wings is brighter. White and bright brown nuances are specific to this butterfly.

As a means of defense, Marine Blue Butterflies additionally exhibit dark blue eyespots on the out ventral wings.

9. Cactus Bee

Cactus Bee

A banded-looking hair bee, The Cactus Bee (Diadasia rinconis) is one of Sonoran’s bees that depends on the desert.

Its adaptations to this habitat mean The Cactus Bee only becomes active in the cactus flowering periods.

Since there aren’t many flowering species here, a low number of flowering cacti also means the number of Cactus Bee numbers can be sometimes endangered.

From saguaro to chora, this is a species that powder itself in pollen all day in the cacti flowering periods.

Mammals in the Sonoran Desert

10. Antelope Jackrabbit

Antelope Jackrabbit

Some of the most unlikely species to be found in The Sonoran Desert include The Antelope Jackrabbit (Lepus alleni).

Identified by its long ears about its body, this is a species with earthy colors that make it blend in with its desert habitat.

Feeding sources may be scarce for this jackrabbit but the species is adapted to Sonoran species.

This adaptation includes feeding on shrubs and cacti but almost any type of soft plant can be eaten by the species.

Apart from its feeding versatility, The Antelope Jackrabbit survives the desert through behavioral adaptations.

This includes only being active at night or going for food early in the morning.

11. Cactus Mouse

Cactus Mouse

A species of rodents with hairless tails and soles, The Cactus Mice (Peromyscus eremicus) found in the desert are mostly nocturnal.

This is a high-heat adaptation that allows the species to thrive in areas where other, often more hairy rodents cannot.

Cactus Mice also show further dietary adaptations to survive the extreme conditions of The Sonoran.

This includes eating a more plant-based diet in the summer and an insect-based diet during the winter.

Some of the typical foods that come from plants the rodents eat on summer nights include seeds.

The rodents reduce their activity during the winter, a time when they eat more insects as plant resources become scarce.

12. Arizona Pocket Mouse

Arizona Pocket Mouse

Golden-gray nuances are specific to the smaller Arizona Pocket Mouse (Perognathus amplus).

The reduced size of the species inspires its name but this type of mouse also shows high creativity when it comes to surviving in the desert.

Much like The Cactus Mouse, the species like seeds. Unlike The Cactus Mouse, The Arizona Pocket Mouse likes to store its seeds.

These seeds are carried back to their burrow, often in their hundreds.

Seeds aren’t ingested but carried in their mouths back to the burrow.

Rodents of the species show further adaptions through their exclusively nocturnal feeding habit which means they are never out in full sun or during the day when they can be spotted by predators.

13. Pallid Bat

Pallid Bat

Reaching a size of up to 2.7 inches, Pallid Bats (Antrozous pallidus) show adaptations to living in The Sonoran Desert.

This is a species that can thermoregulate which means it can lower or raise its internal temperature as a response to the outer temperature and essentially also live in the desert.

Like other bats, it relies on echolocation for food. This means movements trigger its hunting and feeding habits.

Pallid Bats can also locate prey by hearing alone, which is highly responsive in the species.

Even the smallest bug or insect movement can be heard from a long distance by these bats.

14. Canyon Bat

Canyon Bat

Unlike other types of bats in The Sonoran, The Canyon Bat (Parastrellus hesperus) is almost completely white, with short black wings.

Its short wings are practical when it comes to quickly changing the flying pattern.

This is a skill the bat relies on when chasing insects in the air.

Canyon Bats are less likely to adapt their core temperature to the outer temperature and may enter hibernation.

Unlike other hibernating species, The Canyon Bat is a species that can sporadically come out of hibernation to eat before entering back into hibernation.

15. Desert Cottontail

Desert Cottontail

This type of rabbit mostly feeds on cacti such as prickly pear.

Desert Cottontails (Sylvilagus audubonii) are smaller than other rabbits and rarely reach the age of 3.

Most time, this species ends up as food for one of the snakes in this area.

The fact that the species is diurnal doesn’t help either. Apart from the mid-day period, this species can be spotted out for food at any time.

Feeding on plants and cacti, the species may seek out refuge from the highest heat by hiding in the burrows of other species.

This is a habit preferred to digging out its burrow, a very rare occasion in Desert Cottontails.

16. Desert Kangaroo Rat

Desert Kangaroo Rat

The Desert Kangaroo Rat (Dipodomys deserti) is one of the multiple species of The Sonoran Desert that drum their feet.

Such habits are more common in spiders and other mammals, but this capacity is what inspires the name of the species.

Unlike most other drumming species or species that vibrate the sand beneath them for communication, The Desert Kangaroo Rat does it as a means of confrontation.

Rats drumming their feet are actively territorial and a response to this call is typically another rat that comes out of a burrow for a confrontation.

In other drumming species, the vibration of the sand is what initiates the breeding process.

17. Desert Woodrat

Desert Woodrat

The Desert Woodrat (Neotoma lepida) is one of the most territorial types of rodents in The Sonoran Desert.

While it doesn’t fight its own, the rat fights other rat species such as The Desert Kangaroo Rat for resources.

Sometimes invading the burrows of other rats, The Desert Woodrat carries small pieces of wood or branches to block off its entrance, a habit that is the root of the name of such rats.

Desert Woodrats know that food and water are scarce in the desert and act accordingly.

These rats may live close to a type of plant they feed on for a long time just to ensure other rats don’t eat it instead.

18. Kit Fox

Kit Fox

Kit Foxes (Vulpes macrotis) are some of the smallest types of foxes in North America.

Only measuring several inches, these small foxes come in varying coats from yellow to gray, depending on the area of the desert they live in.

Highly secretive, Kit Foxes are nocturnal creatures that live in dens during the day.

Coming out for food at night, the foxes have a diverse diet but often feed on the multiple species of rodents in the area.

Kit Foxes mostly live in groups or small areas in higher numbers.

19. Ringtail


Ringtails (Bassariscus astutus) are among the exceptional animals of The Sonoran Desert which can be raised as pets and domesticated.

A caring species, Ringtails live close to water or in higher numbers close to water across the area of The Sonora and in the entire Southwestern US region.

Ringtails are among the species that also show versatility in diet.

They can eat seeds and fruits in the winter but they are predators in the summer.

Birds are an important part of their diet as these types of animals may live up on trees, mainly on dead trees.

They can also eat prey on the ground. Some of the species they feed on close to water include frogs as well as rodents.

20. Round-tailed Ground Squirrel

Round-tailed Ground Squirrel

Round-tailed Ground Squirrels (Xerospermophilus tereticaudus) are among the species eaten by ringtails in The Sonoran Desert.

Ringtails are only a considerable predator for the species in areas close to the water and are second to snakes, which can easily snatch these squirrels in different areas of the desert.

While small, often diurnal, and prey for snakes and other species, Round-tailed Ground Squirrels use their long tails to deter predators.

They move their tail across the soil to create noise and vibration, much like rattlesnakes use the tip of their tails, mainly to appear more dangerous.

This is a species that can survive almost a decade if it doesn’t fall prey to the multiple predators of the desert.

21. Southern Pocket Gopher

Southern Pocket Gopher

Only found in the Southern parts of The Sonoran Desert, The Southern Pocket Gopher (Thomomys umbrinus) is a brown-black type of rodent.

It lives in underground burrows where it hides in the hottest moments of the day or when it hides from high winds.

This is also a species that remains active throughout the year and an important species in the food chain of various snakes.

Southern Pocket Gophers are a species that’s found in Mexico in higher numbers but which may also be largely absent as a result of predation over long periods.

22. Western Spotted Skunk

Western Spotted Skunk

A high number of Western Spotted Skunks (Spilogale gracilis) is specific to areas of The Sonoran Desert.

This striped species is known for the foul-like spray it uses against common threats from its rear end.

The species is found in many inhabited areas as well and can be quite docile despite its spraying capacity.

Living close to the water source, Western Spotted Skunks survive on rodents and squirrels here.

While they cannot eat large rabbits in the desert, they can eat juveniles.

With sufficient food supplies, The Western Spotted Skunk can live up to a decade.

23. Mexican Wolf

Mexican Wolf

Small Southern parts of the desert are home to The Mexican Wolf (Canis lupus baileyi).

Their populations are scarce, on the other hand. It’s believed there are only hundreds of Mexican Wolves left in The Sonoran and the combined US habitats.

This is a species that survives on large mammals but that hunts for smaller prey in the desert.

Rabbits and squirrels are among the largest types of prey of The Mexican Wolves in The Sonoran Desert.

Outside of The Sonoran Desert, a small number of Mexican Wolves also live in The Chihuahuan Desert, with a similar diet.

Reptiles and Amphibians in the Sonoran Desert

24. Arizona Mud Turtle

Arizona Mud Turtle

A small species that reaches a maximum length of 7.5 inches, The Arizona Mud Turtle (Kinosternon stejnegeri) is found in Sonoran puddled.

This is a turtle that only lives in puddles, next to frogs and different local insects.

It can be found right in the water in the warmest months as a semi-aquatic type of turtle.

The species moves inland and into a burrow for the cooler months.

Also breeding in the summer, The Arizona Mud Turtle feeds on different types of fish and tadpoles but it also eats carrion.

This type of turtle can also go for a long period without water. It can be years before it comes out of its burrow in high drought periods.

25. Sonoran Box Turtle

Sonoran Box Turtle

The Sonoran Box Turtle (Terrapene ornata luteola) is a type of turtle that can live in drier areas, such as The Sonoran Desert.

Adapted to living close to puddles here, these types of turtles have a round boxy shape and are active up until October.

They live in small areas where they can find food but they spend most of their lives on dry land and in burrows.

A typical Sonoran Box Turtle can live almost a full decade, with sufficient access to food.

It thrives on insects and small animals but this species can also eat vegetation, which can be scarce in its habitat.

These turtles also don’t travel far from the areas they are born in and they can even return to the area if they venture out at one point in their lives.

26. Sonoran Desert Toad

Sonoran Desert Toad

The Sonoran Desert Toad (Incilius alvarius) is the largest type of native toad in the desert.

Growing to a size of up to 7.5 inches, it comes in green or green-brown colors of a dark nuance.

This species lives close to springs, water accumulation, and canals. It can live around reservoirs as well.

A nocturnal species, this is an adaptable toad that avoids full sun and which can repurpose the burrows of rodents to hide from the sun.

Sonoran Desert Toads are prolific breeders in the summer after it rains.

A single female toad can lay thousands of eggs in a lifetime.

This toad is further known for secreting poison with a white milky substance off its skin.

27. Great Plains Toad

Great Plains Toad

Not far behind the Sonoran Desert Toad in terms of sizing, The Great Plains Toad (Anaxyrus cognatus) is a species that may reach a size of up to 7 inches.

This is a species found throughout much of Arizona and it can be spotted in The Sonoran Desert in the monsoon season.

Breeding starts with the rain here but there are instances when the toad can start breeding even before the rain starts if it manages to find a water source.

This species is further known for the toxins it secretes. These are at least irritating to animals in the desert as they used to be to those in other areas.

Great Plain Toads were once a species of California as well.

28. Sonoran Spiny-tailed Iguana

Sonoran Spiny-tailed Iguana

Sonoran Spiny-tailed Iguanas (Ctenosaura macrolopha) are dark types of iguanas that live in the desert.

This is a species that may be all-black or dark with black, gray, or brown bands.

Iguanas of this type feed on the different types of vegetation found here, which may be limited to species of cacti.

The crests which are seen on males inspire the spiny name of the species. Most of its spines are located on the tail.

29. Sonoran Collared Lizard

Sonoran Collared Lizard

A species seen in neutral colors, The Sonoran Collared Lizard (Crotaphytus nebrius) gets its name from the black bands behind its neck.

This species comes in brown nuances or yellow-brown nuances. It features additional yellow spots on the dorsum.

Orange stripes are further seen along the black-collared sections.

As with many species of The Sonoran Desert, the active period of The Sonoran Collared Lizard is up until November.

30. Desert Horned Lizard

Desert Horned Lizard

A wide spiny lizard, The Deserted Horned Lizard (Phrynosoma platyrhinos) with its subspecies lives in The Sonoran Desert.

Its short but stocky physique also makes the species known as the Horny Toad for its resemblance with toads.

Desert Horned Lizards have short spines all over their body.

These spines may act as a deterrent but the lizard can also push them against the perceived prey if needed.

The Desert Horned Lizard features 2 distinctive horn-like spines at the top of the head which further act as a warning sign to potential predators.

While it has a varied diet, this species survives the desert by feeding on ants.

31. Desert Iguana

Desert Iguana

Desert Iguanas (Dipsosaurus dorsalis) are among the few species of bright iguanas found in The Sonoran Desert.

This is a species that can appear white, but it mostly has a base bright cream color with additional darker dorsal patterns.

Desert Iguanas can eat plants and various other species of insects in the desert.

They favor ants but they can also eat different types of flowering plants including various shrubs.

The local medicinal herb creseote bush, also found in The Mojave Desert is among their favorite types of plants to eat.

While they can reach a length of up to 24 inches with their tails, these types of iguanas are still eaten by various predators such as foxes.

32. Desert Tortoise

Desert Tortoise

Native to the area The Sonoran, Desert Tortoises (Gopherus agassizii) are among the longest-living species here.

This is a species that can sometimes outlive humans as some Desert Tortoises can live up to 80 years.

Most of these 80 years are spent underground.

The turtle hides from the sun to avoid desiccation and they dig deep burrows where they hide only to come out for food.

Their food is represented by young vegetation and cacti.

Ravens and birds, in general, are some of its common predators, including its eggs which are laid in small numbers.

While they can be kept as pet turtles, Desert Tortoises are prone to respiratory issues.

33. Common Mexican Tree Frog

Common Mexican Tree Frog

The Common Mexican Tree Frog (Smilisca baudinii) is found in the Southern parts of The Sonoran, but not in high numbers as in other areas.

As expected, it lives around water, including reservoirs and puddles.

Temporary water accumulation tends to draw these frogs out of the ground to breed.

Otherwise, they can remain elusive as they rarely move for food during the day.

Common Mexican Tree Frogs are also highly variable in colors. From green to brown, this is a species that can be confused with other frogs as it comes in a patterned dorsum.

34. Sidewinder


Sidewinders (Crotalus cerastes) or Sidewinder Rattlesnakes are a venomous species of The Western Sonoran.

These snakes possess a highly venomous bite, but which is not as venomous as the bites of other rattlesnakes in The United States.

Reaching a maximum length of 31.5 inches, Sidewinders can live up to 5 years.

Moving sideways on the sand, this is a species dominated by its locomotion methods which humans rarely encounter.

Its venomous bite is often treated with antivenom even if not perceived as highly painful at first.

35. Arizona Black Rattlesnake

Arizona Black Rattlesnake

Slightly larger than Sidewinder Rattlesnakes, Arizona Black Rattlesnakes (Crotalus cerberus) can grow to a size of just over 40 inches.

They can appear mostly black or almost completely black and can be found in areas of the desert with rodents and amphibians.

The species found in the desert is also known for having the capacity to change colors.

It’s not yet known why this snake can change colors, often quicker than other species with this capacity.

36. Gila Monster

Gila Monster

Gila Monsters (Heloderma suspectum) are the only venomous reptile in The United States also found in The Sonoran.

Black and pink or yellow-pink nuances are specific to this type of lizard which is considered highly venomous to its prey.

It delivers venom by biting and using its sharp, long, and backward-angled teeth.

While not life-threatening to humans, its bite can still lead to skin conditions, nausea, and general weakness.

Even young Gila Monsters that have just crawled out of their eggshells can bite and inject venom.

Birds in the Sonoran Desert

37. Burrowing Owl

Burrowing Owl

A species into acoustic mimicry, Burrowing Owls (Athene cunicularia) show completely different habits to other owls.

These types of owls nest in the ground, unlike most other owls.

They retreat into the burrows of rodents or ground squirrels in the desert.

Mimicry tactics don’t stop here as Burrowing owls can even hiss.

This is a direct mimicry of rattlesnake hissing and nesting, a habit believed to deter at least some of its predators.

38. Gambel’s Quail

Gambel’s Quail

Only found in the Southwestern deserts of The US and Mexico, Gambel’s Quails (Callipepla gambelii) have mostly blue plumage.

Both males and females feature distinctive crests and can be seen in the breeding season as they rarely flock together.

These types of birds survive the desert climate by eating plants and seeds.

Juveniles mostly feed on seeds while adult Gambel’s Quails also feed on plants.

39. Cassin’s Vireo

Cassin’s Vireo

This type of bird (Vireo cassinii) is found throughout The Sonoran Desert as well as across the West Coast.

A migratory species, the bird also ends up here during migration but it prefers woodlands and open woodlands.

This is a species with gray and white plumage and a dark gray beak.

A gray head and gray wings make up the upper part of its plumage while its underbelly is almost bright white.

40. Phainopepla


A dark type of bird, Phainopepla (Phainopepla nitens) is a species mostly known for its presence in hot climates such as those in the desert.

This is a species that prefers desert oases and which has distinct colors for males and females.

Males have a blue-black color while females are dull gray.

The birds feed on seeds, fruits, and small insects such as ants.

Phainopeplas are also birds that can peel off the skin of their fruits with their beaks.

41. Cactus Wren

Cactus Wren

Cactus Wren (Campylorhynchus brunneicapillus) is seen on local cacti species and trees. They don’t eat these cacti as they eat insects.

Still, Cactus Wren build nests on or in cacti to protect their eggs.

They prefer local species such as saguros but they can also nest on trees such as yucca.

Found in The Sonoran and Chihuahuan deserts, Cactus Wren has now expanded their range up to coastal California.

42. Anna’s Hummingbird

Anna’s Hummingbird

These types of hummingbirds (Calypte anna) are found throughout The Sonoran Desert.

They also move up along The West Coast as temperatures here change as a result of climate changes.

Anna’s Hummingbirds are mostly known for the iridescent heads of males.

Pink or pink-violet iridescence is seen across the metallic-looking head of the male. Even more, male Anna’s Hummingbirds also show metallic-sounding vocalizations.

They can live in The Sonoran throughout the year or migrate here from more Northern territories.

43. Black-tailed Gnatcatcher

Black-tailed Gnatcatcher

As the name of the species implies, Black-tailed Gnatcatchers (Polioptila melanura) live off insects in the desert.

They can eat different flies by chasing them or they can pick up spiders off the ground.

Black-tailed Gnatcatchers are also different than other species as they don’t live solitary lives. They live in pairs and feed in pairs.

Eggs are laid directly in the vegetation of the desert.

44. Crissal Thrasher

Crissal Thrasher

These gray birds (Toxostoma crissale) show long curved beaks.

They are part of a small group of sedentary birds found in the Southern US and in The Sonoran Desert.

Rarely flying away far from their current location, these birds prefer to walk.

Even walking far isn’t an option for the species that knows how to protect its eggs and young. For example, it builds nests in sheltered locations such as under vegetation.

45. Gila Woodpecker

Gila Woodpecker

Woodpeckers also live in The Sonoran Desert. Unlike woodpeckers in other areas of the country, Gila Woodpeckers (Melanerpes uropygialis) mostly build their nests in cacti.

Saguaros are among their typical hosts where they build their nests. When abandoned, these nests are often repurposed by other birds in the region.

Feeding on fruits and seeds, these woodpeckers don’t eat the cacti themselves.

46. Greater Roadrunner

Greater Roadrunner

A type of bird that runs, The Greater Roadrunner (Geococcyx californianus) is also found in The Sonoran Desert.

It’s here that it lives either on its own or in pairs.

They also build nests in pairs. Females use the materials gathered by males to create the ground-level nest.

The species is territorial and aggressive towards other Great Roadrunners. Males are known to set up feeding perimeters where they don’t accept other males.

Fish of the Sonoran Desert

47. Desert Pupfish

Desert Pupfish

Desert Pupfish (Cyprinodon macularius) are among the few species of fish found in The Sonoran Desert.

The species mostly inhabits the area of The Sonoran Delta or The Colorado River Delta where they live in shallow water.

Male and female Desert Pupfish come in different colors.

A bright blue nuance is specific to males while female Desert Pupfish are mostly silver-gray.

48. Gila Topminnow

Gila Topminnow

Gila Topminnows (Poeciliopsis occidentalis) are named after the Gila River they inhabit.

These types of fish are small and colorful. A yellow color is specific to this species.

Rare types of physical traits also include a rounded belly and a black stripe along its sides.

Males Gila Topminnows are also half the size of females, never reaching a length of 1 inch.

49. Loach Minnow

Loach Minnow

Loach Minnows (Rhinichthys cobitis) are also found in the streams of the Gila River but are at least twice the size of Gila Topminnows.

These types of fish grow to a size of over 2 inches and prefer to live close to rocky areas in the streams and rivers of the Gila River and San Pedro River.

They feed on whatever insects they can find at the bottom of the rivers or streams they swim in.

50. Sonora Sucker

Sonora Sucker

Sonora Sucker fish (Gila Sucker) also prefer rocky and turbulent areas where they can share their habitats with trout or Loach Minnows.

These fish feed on small crustaceans and they show a tendency to live in the same area.

A species of fish that are highly sedentary, Sonora Suckers can be easily separated from other species by the shape of their fins.

These fish have square back fins and may reach a size of up to 30 inches.
