How Big Can Bats Get?

Although they’ve been dubbed creepy, frightening, and spooky, bats are a significant species that have an impact on our daily lives that we might not even be aware of. 

Bats are the unsung heroes of the night, pollinating our favorite fruits, consuming bothersome insects, and inventing medical wonders. 

Bats Species

Worldwide, there are about 1,400 different species of bats. With the exception of the polar areas and the world’s most harsh deserts, bats can be found almost everywhere. 

Both the size and shape differences are striking. The world’s smallest mammal, the Kitti’s hog-nosed bat (also known as the Bumblebee Bat), weighs less than a penny. Flying foxes, on the other hand, can have wingspan of up to 6 feet. 

About 45 different species of bats can be found in the United States, Canada, and U.S. territories in the Pacific and Caribbean.

How Big Can Bats Get : Largest Bats

It’s not helpful that some bats have been known to transmit horrifying diseases, and their nocturnal habits and leathery wings don’t help either. 

However, bats are crucial to the environment. They consume insect pests like mosquitoes, aid in flower pollination, and aid in the expansion of plants by dispersing seeds. 

Fruit bats, often known as megabats, are the largest species of bat in the world, though not all fruit bats reach enormous size. Here are some of the world’s largest species. 

Greater Horseshoe Bat

The horseshoe bat seen in Europe that is the largest is this one. Along with northern Africa and central and eastern Asia, it can also be found throughout Europe. 

Because its winter and summer encampments are only around 19 miles apart, it is regarded as non-migratory.

This bat’s length from nose to tail can reach 4.5 inches, and females are slightly bigger than males. They can be identified by their nose leaves and have a 14 to 16-inch wingspan. 

The nose leaf has a pointy tip and a horseshoe-shaped bottom, giving the creature its name. It has light grayish brown wings and fluffy gray fur. 

It is a species that has a lengthy lifespan and can survive for up to 30 years. Mostly moths are what it eats.

Greater Spear-Nosed Bat

The average length of the males in this species, which is the second-largest in Central and South America, is 5.23 inches, while the average length of the females is 4.9 inches. 

The female’s wingspan, at about 1.8 feet, is bigger. The animal is distinctive for having a spear-shaped nose leaf. 

It eats birds, which is unusual, along with other bats and small rodents that it can handle. If the usual prey isn’t available, it will also eat fruit and insects. 

It spends the majority of the day in vast colonies located in caves and deserted structures and comes out at dusk. 

Spectral Bat

The largest bat in the Americas is this tailless species, which can grow as long as 5.3 inches and has wingspan of more than 3 feet. 

It features wide, rounded ears, a huge nose leaf, and fine, reddish-brown fur. Although experts are unsure of its breeding season, it is quite rare for bats in that it forms lifelong bonds with its partners. 

They are aware that from late spring to mid-summer, female bats give birth to a single young, which is likewise unusual for bats as the male tends to the young.

Because it was originally believed that the spectral bat consumed blood, it is also known as the great fake vampire bat. 

Even if that is untrue, due to their excellent sense of smell, spectral bats are regarded as some of the best hunters in the woods of Central and South America, second only to jaguars. 

They eat other bats, small birds, rodents, frogs, and lizards. Once they’ve located a target, they swoop down and use their vicious bite to break its skull.

Greater Noctule Bat

This animal, one of the few species of bats that feeds on creatures larger than insects, measures about 6 inches from nose to tail and has an 18-inch wingspan. It preys on birds. 

Additionally, it hunts flying birds. It uses echolocation and its wings, which are very thin and delicate, to do this. 

Even in the dead of night, the animal can outmaneuver its victim because to its wings, which are more prone to damage. It can be found across Europe, western Asia, and North Africa.

Wroughton’s Free-Tailed Bat

This animal’s tail is free, or not linked to its wing membranes, hence its name. 

There isn’t enough information about this bat to assign it a conservation status, despite efforts to protect it, despite the fact that it appears to be rare and can only be found in two locations in India and one cave in Cambodia.

The Wroughton’s free-tailed bat has huge ears that point forward, a large nose pad on a furless face, and measures about 6 inches from head to tail. 

The top of the animal’s head, its back, and its rump are covered in velvety, dark brown fur, yet its shoulders and back are covered in silvery fur.

According to scientists, both males and females of the species consume insects and they both have a throat sac.

Franquette’s Epaluetted Bat

West African nations like Niger, Nigeria, Cameroon, and Cote d’Ivoire are home to this species. 

Additionally, it exists in Zambia, Angola, the Congo, and the Sudan. It is 5.51 to 7.01 inches long and has a 2-foot typical wingspan. 

Scientists don’t understand the mating habits of these creatures because they tend to live alone or in tiny groups. 

They believe that they have year-round breeding rather than a specific breeding season. 

The white patches on its shoulders, which contrast with the majority of the remainder of its fur’s dark brown or orange hue, are whence it gets its name.

Although a frugivore, Franquet’s epauletted bat has an unusual method of eating. 

The fruit is crushed against the back of the animal’s tough palate, which then ingests the juice and the seeds before spitting up the pulp. Also, it consumes flowers. 

Despite being used as bushmeat, the animal’s conservation condition is of little concern.

Madagascan Flying Fox

The largest bat in the island nation of Madagascar in Africa is called the Madagascan flying fox. 

It can grow to be between 9 and 10.5 inches long with a wingspan of 4 feet. It has brown fur, gray or black wings, and an alert, vulpine visage. 

Both sexes are similar save from the male having a little larger head than the female.

This flying fox prefers to roost in mature trees that can accommodate vast colonies rather than in caves. With its leathery wings wrapped around it, it hangs upside down. 

The flying fox consumes fruit, particularly figs, and as the seeds move through the animal’s digestive system, they are dispersed far. 

Additionally, it consumes flowers, leaves, and nectar. The kapok tree, an ornamental grown for its beauty and whose blossoms are used to prepare teas and soups, is thought to be pollinated by the Madagascan flying fox.

Hammer-Headed Bat

In the jungles of central Africa, one might find this monster, whose unfortunate scientific name is Hypsignathus monstrosus. 

Males can weigh twice as much as females and are longer. A large male can weigh about a pound and measure up to 11 inches in length, while females can reach lengths of 8.8 inches. 

The hammer-headed bat is the biggest on the continent of Africa due to its size.

The males of the species are known as “hammerheads” because of their big larynxes and expanded structures on their heads, which aid in the transmission of their vocalizations. 

Large lips, a humped, warty snout, large cheek pouches, and a cleft chin are a few of them. It’s one of the truly ugly animals there is. 

The female resembles a flying fox more than the male does. The male hammer-headed bat is regarded as a pest in some areas because of the loud noises it makes. Its conservation status is, however, of little importance.

The Great Flying Fox

The Bismarck Flying Fox, another name for the Great Flying Fox, is a species that lives in New Guinea and the Bismarck Archipelago. 

It is the largest bat to be seen in Melanesia, measuring 10.5 to 13.0 inches for males and 9.2 to 11.0 inches for females. Additionally, at up to 3.5 pounds, it is one of the heaviest. 

It consumes fruit, mainly figs, like the majority of other flying foxes. It looks for food every day and every night.

Despite having a bare back and lighter-colored hair on the rump, this bat’s fur can range in hue from golden brown to russet. 

The gregarious bat enjoys forming colonies that might number in the thousands and dangle from the branches of trees. 

Since the great flying fox frequently resides close to the water, it occasionally spots fruit floating on the waves and gathers it.

Golden-Crowned Flying Fox

The largest bat in the world, it is also known as the golden-capped fruit bat. Its size is genuinely astounding. 

Although it is shorter than some other species in length (7.01 to 11.42 inches), it makes up for this with a 5.6-foot wingspan and a maximum weight of 2.6 pounds. 

It can be found in the Philippines and dwells in mangrove forests, swamps, and hardwood woods close to cliff edges, among other places where it may avoid interacting with people. 

Short, silky, and varied, the bat’s fur is brown or black on the head, russet across the shoulders, cream on the nape of the neck, and has golden hairs all over the body.

These bats indeed have an odd smell that people find repulsive. Scientists believe that the bats use this scent to communicate.

Being a frugivore, the golden-crowned flying fox aids in the spread of seeds, particularly fig seeds. Its lifespan in the wild and its breeding practices are unknown to scientists. 

It prefers to roost alongside other varieties of fruit bats, they have noticed. The golden-crowned flying fox leaves its colony around dusk in search of fruit and returns just before dawn. 

The golden-crowned flying fox is imperiled in the Philippines as a result of significant habitat loss.


It’s true that many individuals get uneasy around bats. Some people find them too strange to handle as an animal that has developed genuine flight.
