20 Types Of Bats (Pictures and Identification Guide)

Bats are important in controlling insects and pollinating. They are social, living in groups, sometimes hundreds at a time. Bats are amazing mammals from the Microchiroptera family.

The majority of bats live on insects, including moths, cockroaches, beetles, and mosquitoes. The smallest of bats can eat up to five hundred insects in an hour, which means a colony can eat up to the weight of two blue whales in one night.

Interesting Facts about Bats

Before looking into the different types of bats there are in the world, have a look at some of the interesting facts about these mammals.

  • Bats are the only flying mammal. Flying squirrels do not fly, they glide, where the bat sustains flight.
  • Not all bats are nocturnal. While the majority of bats do hunt at night, some hunt early in the evening or at dawn.
  • Bats range in size, some are so small, weighing only 2 grams. The hog-nosed bat is not only small, it is the smallest mammal in the world.
  • They are not the same as birds. Their wings are different, there are no feathers, and are made up f fingers.
  • They have an overpowered cardiovascular system, giving them the additional power they need to fly. Their hearts must also help keep blood circulating when they roost upside down.
  • Bats don’t flap their wings like birds, they almost swim through the air, using a flap and guide technique, which has proven very effective.
  • They can eat a lot of bugs and be beneficial in reducing insects in or around the home.
  • Farmers encourage bats, as they can use fewer pesticides on their crops, saving time and money.
  • Bats don’t enjoy winter and they will either hibernate or migrate to the south during the cold months.
  • Their hearts can beat anywhere from four beats per minute, during hibernation to more than one thousand beats per minute, when flying for an extended period.
  • They are designed to hang upside down. Hanging upside down reduces the risk of predators locating and reaching them.
  • Hanging upside down gives the bat enough speed when they are ready to fly, they simply drop and fly. Their back legs are small and are not enough to get speed to take off. They have to drop down in order to get started with the flight.
  • Most of the time you won’t notice bats, because they are out hunting at night, but they are the second most populous mammal species in the world. Rodents are the first. There are more than one thousand three hundred species of bats in the world.
  • Bats are food for hawks, eagles, owls, raccoons, snakes, and even humans
  • Some are considered endangered due to their habitats being destroyed
  • Not all bats are blind, some have excellent vision. Those with poor sight rely on an echo call, known as echolocation, which helps them identify prey and obstacles.
  • Yes some bats drink blood, but it is animal blood and not human blood
  •  Some bats eat fruit or feed on nectar
  •  They can live in large colonies of hundreds or thousands of bats

Types Of Bats

1. Old World Fruit Bats

Old World Fruit Bats

Old World Fruit Bats comprise more than one hundred and eighty species. These bats have large eyes and are widely distributed from Australia to Southeast Asia to Africa. They live in trees, caves, buildings, and rocks.

The most well-known old-world fruit bat is the flying fox, which lives on tropical islands, and can grow to 2.8 inches in body length with a 10-inch wingspan. They vary in color, with some having red or yellow stripes or spots.

They rely on their vision rather than relying on echolocation when avoiding obstacles.

2. Mouse-tailed Bats

Mouse-tailed Bat

The Mouse-tailed Bat is an insectivorous bat that has six species within a single genus. They can be found from North America to Sumatra and Thailand, along with caves, houses, and arid regions. They have been sighted at the Egyptian pyramids.

They are small bats growing to 6cm in body length and weighing up to 14 grams. They have slender limbs with a long tail that is completely hairless. The tail is around the length of the body. They have a soft and short sandy-colored fur with big ears and large black eyes.

When food is scarce, these bats can live off their fat reserves.

They live in colonies, which comprise thousands of bats, some groups are male only, female only and there are also mixed groups.

They are fast fliers but get exhausted quickly, which means they also run on the ground.

3. Hog-nosed Bat

Hog-nosed Bat

The Hog-nosed Bat is also known as the bumblebee bat and is a threatened species occurring in southeastern Myanmar and western Thailand where they live in limestone caves on the edge of rivers.

These are small bats and are considered the smallest mammal in the world.

They have a gray to red/brown colored coat and a snout that resembles the snout of a pig.

They average around one hundred bats in each colony, where they feed in the evenings and at dawn.

Those in Thailand are considered at risk of extinction, due to habitat degradation and roosting sites being disturbed.

These small bats grow to 1.3 inches (3.3cm) in body length and weigh up to 2 grams.

4. False-vampires


False-vampires bats do not feed on blood but are known to eat small vertebrates, including mice, lizards, and other bats.

These bats rely on echolocation to detect prey and obstacles. They hunt spiders and insects. Their lifespan is around seven years.

This bat has been involved in extensive research, especially regarding the SARS coronavirus. They are hunted as food in sub-Saharan Africa and Southeast Asia.

After the 2002 – 2004 SARS outbreak, numerous animals species were examined to see if they were a reservoir of the virus.

From 2003 to 2018, forty-seven SARS-related coronaviruses were detected in horseshoe bats. When the SARS-CoV2 virus outbreak occurred in 2019, it was discovered to be similar to the viruses already found in the horseshoe bat.
