27 Types of Scorpions (Pictures and Identification)

Scorpions are often feared for their aggressive looks and venomous sting. While most types of scorpions aren’t venomous, some species are considered deadly to humans.

Venomous scorpion stings are treated with medications according to symptoms. Analgesics are used on most people stung by scorpions. Since their sting affects the cardiovascular system, people stung by scorpions may also be treated with antivenom and vasodilators.

What Are Scorpions?

Scorpions represent a species of arachnids with 8 legs, pincers, and a thick segmented tail. This tail is known for its upward curved position. It can be used to sting with or without venom in offense or defense.

Scorpions live all around the world, especially in the Southern Hemisphere, in tropical areas, and to a lesser extent even in the Northern Hemisphere.

Scorpion Identification


Scorpions are arachnids, similar to spiders. Just as spiders, scorpions have 8 legs and the capacity to sting.

Scorpions come in many colors depending on their habitat. Their diet may also fluctuate depending on where they live.

Scorpions are black, tan, red, or brown arachnids with pincers and a thick tail. Their thick segmented tails are curved upwards and ready to be used against prey or to defend themselves from predators.

As arachnids, scorpions share some traits with spiders. These traits include diet as scorpions mostly eat insects, but they may also eat vertebrates.

Scorpions are known for feeding on a wide range of insects. They prefer grasshoppers, spiders, ants, wasps, and centipedes. They also eat termites and woodlice.

Some species of scorpions are even known for eating lizards. They might also sting and overpower small snakes.

Scorpion eating insect

While fearsome predators scorpions are also predated by some species. Birds, snakes, and lizards are among the animals that eat scorpions.

Most scorpion species use the same method to catch prey. They quickly grab an insect with their pincers and while holding it down using the tip of their tails to sting the victim and immobilize it for consumption.

Scorpions have widespread distribution. They live on most continents and have adapted to various climates.

Most scorpions are found in very hot climates and deserts,
