Animals That Glide: How Gliding Works

Animals that glide do something different from ordinary jumping and different from true powered flight. They launch from a high place, spread a body surface that catches air, and control the fall well enough to travel sideways before landing. Some use furry membranes, some use expanded ribs, some use webbed feet, and some use fins or flattened bodies. The result is not magic and not simple falling. It is controlled aerial movement shaped by anatomy, gravity, air resistance, and behavior.

This makes gliding one of the clearest examples of how animals solve movement problems without all evolving the same body plan. A flying squirrel, a flying fish, a gliding frog, and a flying snake look nothing alike, yet each uses the same basic trade-off: give up height to gain distance, escape danger, reach food, or move through a complicated habitat without taking the long route down.

Quick Answer

Animals that glide include flying squirrels, sugar gliders and other gliding possums, colugos, flying dragons, gliding frogs, flying snakes, flying fish, and some canopy ants. They are not all closely related. Gliding has appeared in many animal groups because forests, cliffs, tall plants, and even the ocean surface create situations where controlled descent can be useful.

The simplest way to understand gliding is this: a glider cannot climb upward through the air by flapping the way a bird or bat can. Instead, it begins above the landing point and uses a body surface to slow the fall, steer, and turn part of that downward motion into forward motion. A Biology Open review of gliding locomotion describes gliding as movement in which an animal travels downward and horizontally without producing thrust, relying on lift and drag while descending.

What Counts as Gliding in Animals?

Not every animal that jumps, spreads its body, or falls from a tree is truly gliding in the useful biological sense. The key difference is control. A gliding animal usually has body structures and behaviors that let it slow its descent, aim toward a landing area, and adjust body posture in the air. That is why a leaf falling from a tree is not an animal gliding, and a squirrel that simply drops onto a lower branch is not doing the same thing as a flying squirrel spreading a membrane between its limbs.

Gliding versus true powered flight

True powered flight requires an animal to generate thrust in the air, usually by flapping wings. Birds, bats, and many insects can produce repeated strokes that help them stay aloft, climb, turn, or fly level for a time. A gliding animal does not have that same power source during the glide. It may steer beautifully, but it generally begins high and ends lower.

This is why common names can be misleading. Flying squirrels do not fly like bats. Flying fish do not fly like seabirds. Flying dragons are lizards that glide, not dragons in the fantasy sense. Those names are memorable, but the movement is better understood as controlled descent.

Gliding versus falling

Falling is mostly uncontrolled downward movement. Gliding is a fall shaped into travel. A glider uses air resistance and lift, the upward force created as air moves around a body surface, to reduce the steepness of its descent. It also adjusts posture to control direction. That control may come from stretching limbs, changing tail angle, flattening the body, spreading webbed toes, or undulating through the air.

Some gliders are more maneuverable than others. A flying squirrel can use its tail and limb position to prepare for landing on a tree trunk. A flying snake can flatten and wave its body while descending. A flying fish can hold enlarged fins out like wings after launching from the water. The details differ, but the shared idea is control.

Why control matters more than distance alone

People often ask which animal glides the farthest, but distance alone can be misleading. A long glide from a very high launch point may not be more impressive than a short, accurate glide through dense branches. For many animals, landing safely matters more than traveling the maximum possible distance.

In forests, a missed landing can mean falling to the ground, losing time, using extra energy, or becoming exposed to predators. In the ocean, a flying fish that stays just above the water for a brief glide may avoid a chasing predator even if it does not travel as far as a mammal moving between tall trees. Gliding is useful because it changes where an animal lands, not just because it looks dramatic.

Why Gliding Evolved in So Many Animals

Gliding has evolved in unrelated animals because similar problems can favor similar solutions. Tall trees, broken canopies, cliffs, and predator pressure all create movement challenges. For a small animal high above the ground, dropping straight down may be risky, climbing down may be slow, and jumping blindly may be dangerous. Gliding offers another option.

Escaping predators

Gliding can help an animal leave a dangerous spot quickly. A small mammal on a branch may not want to climb past a predator on the trunk. A frog sitting on vegetation above water or a forest floor may benefit from leaping away and widening its body surfaces to slow the descent. Some gliding animals also use color, camouflage, nighttime activity, or sudden movement along with gliding.

Still, gliding should not be treated as a universal escape trick. Different species use it in different ways. Some glide mainly between feeding areas. Some use it after being disturbed. Others may climb, hide, bite, or flee along a branch instead of launching. The safest wording is that gliding can help with escape in some animals and some situations, not that every gliding animal uses it the same way.

Moving between trees without climbing down

Forest canopies are not smooth roads. Branches end. Trees are separated by gaps. Predators may hunt on trunks or on the ground. A glider can cross some gaps without descending all the way, which may save time and reduce exposure. This is especially useful for animals that feed, nest, sleep, or travel high in trees.

Gliding is closely tied to climbing. Most tree gliders still need claws, gripping toes, strong limbs, and balance because a glide begins and ends on a surface. Launching is only one part of the movement. A successful landing requires the animal to slow, aim, contact the surface, grip, and often climb again.

Searching for food, mates, and shelter

Gliding can expand the area an animal can use without requiring a long ground route. A gliding mammal may move between feeding trees. A flying dragon may shift between tree trunks while searching for insects or interacting with other lizards. A gliding possum may travel through a patchy canopy where food is scattered.

This does not mean gliding is free. An animal must climb to a launch point, choose a landing path, and manage the risk of wind, rain, obstacles, and predators. Gliding is a trade-off. It can reduce one cost while creating another.

The Main Body Features That Help Animals Glide

Gliding bodies are diverse, but most gliders share one broad need: more surface area. A larger surface lets the animal interact with more air during the descent. That can increase drag, help produce lift, and give the animal more time to steer before landing.

Skin membranes and patagia

Many famous gliding mammals use a patagium, a sheet of skin that stretches between body parts. In flying squirrels, the membrane stretches between the front and hind limbs. In sugar gliders and their relatives, it can run from the front foot area to the hind ankle. In colugos, the membrane is especially extensive and reaches from the neck region to the limbs and tail.

The membrane alone is not the whole story. The animal must spread the body at launch, hold a useful shape in the air, adjust posture during the glide, and prepare for landing. A patagium is like a biological wingsuit, but it works only because the animal controls it with muscles, limbs, senses, and practice.

Flattened ribs, limbs, and body shapes

Not all gliders use limb-to-limb membranes. Flying dragons, which are lizards in the genus Draco, use elongated ribs that support winglike skin surfaces. Flying snakes flatten the body and use side-to-side waves as they descend. Some gliding ants are small, wingless insects that can right themselves in the air and aim back toward a tree trunk.

These examples show why gliding is not one body design. It is a movement outcome produced by many designs. A broad membrane, a flattened body, enlarged ribs, webbing, fins, or flexible posture can all help an animal slow and steer a descent.

Webbed feet, fins, and steering surfaces

Some gliding animals look less like wingsuit mammals and more like animals with extra steering surfaces. Gliding frogs may have large webbed feet, fringes of skin, and flattened body positions that help them parachute or glide from vegetation. Flying fish use enlarged pectoral fins, and in some species pelvic fins also contribute to the winglike surface.

Tails can also matter. They may help with balance, braking, or final landing adjustments. This is especially obvious in many mammals, where a long tail can act as a stabilizer during a glide and a balance tool after landing.

Mammals That Glide

Gliding mammals are among the best-known examples because their membranes are easy to see when they spread their limbs. They also show an important point about evolution: different mammal groups have arrived at gliding independently. A flying squirrel is a rodent, a sugar glider is a marsupial, and a colugo belongs to its own unusual mammal group.

Flying squirrels

Flying squirrels are rodents that glide between trees using a patagium stretched between their limbs. Their name can confuse people because they do not flap wings to fly upward like bats. They leap, spread the membrane, steer in the air, and land on another tree or surface. Their long tails can help with stability and braking.

Many flying squirrels are nocturnal, which means people may live near them and rarely see them. North America has flying squirrels, and many more species occur in Asia. Because they rely heavily on trees, cavities, and connected woodland structure, their movement is shaped by the vertical world of trunks and branches rather than open ground.

Sugar gliders and other gliding possums

Sugar gliders are small marsupials, not rodents. They belong to a group of gliding possums in the genus Petaurus. The Animal Diversity Web overview of Petaurus explains that these animals have a patagium connecting the front feet to the back ankles and can change direction and speed while moving between tree limbs.

Sugar gliders are sometimes kept as exotic pets, but their wild biology should not be reduced to a cute pet image. They are social, nocturnal, tree-living animals with complex space, diet, and welfare needs. Readers should not capture wild gliders, disturb nests, or assume that a viral video shows appropriate care.

Colugos

Colugos are often called flying lemurs, but that name is doubly misleading. They do not truly fly, and they are not lemurs. They are mammals of Southeast Asia that are highly specialized for life in trees. Their gliding membrane is one of the most extensive among mammals.

The Animal Diversity Web profile of the Philippine colugo describes a patagium that stretches from the side of the neck to the fingers, toes, and tip of the tail, and notes that no other gliding mammal has such an extensive membrane. This body plan helps explain why colugos are often highlighted as exceptional mammalian gliders.

Reptiles and Amphibians That Glide

Gliding is not limited to furry mammals. Some reptiles and amphibians have evolved remarkable ways to move through the air without true wings. These animals are especially useful for understanding how different body parts can be turned into air-catching surfaces.

Flying dragons

Flying dragons are small arboreal lizards in the genus Draco. Their most famous feature is a pair of winglike membranes supported by elongated ribs. When the lizard launches, those structures spread out from the sides of the body and help it glide toward another tree or lower surface.

An Animal Diversity Web profile of Draco volans reports that this lizard spreads its wings after jumping and can generally glide about 8 meters on average. The same profile also notes that the lizard uses gliding as movement, while climbing is used when escaping danger in the behavior described there, which is a good reminder not to oversimplify every glider as using the same strategy.

Gliding frogs

Gliding frogs, including Wallace’s flying frog and other tree frogs, use large webbed feet and extra skin surfaces to slow and steer their descent. They live in tree-rich habitats where a leap from vegetation can become more controlled when the toes spread wide and the body flattens.

The Animal Diversity Web account of Wallace’s flying frog describes the frog as tree-living and able to glide because of extremely webbed feet and skin flaps. For readers, the important point is not that the frog flies like a bird. It is that a frog body, with the right webbing and posture, can turn a leap into a controlled descent.

Flying snakes

Flying snakes are among the strangest gliders because they have no limbs or wings. They launch from trees, flatten the body, and undulate through the air. That motion helps them control the glide rather than simply dropping like a rope.

A University of Chicago summary of flying snake research describes how these snakes flatten from head to vent and move in an S-shaped pattern while gliding. The same research summary discusses turns during glides, showing that their aerial movement is active and controlled.

Because flying snakes are still snakes, they should be treated with caution and respect. They are not animals to handle for curiosity, and their gliding ability is not a reason to approach or provoke them. The safe way to appreciate this behavior is through reputable footage, zoo education, and field research, not direct contact.

Fish and Invertebrates That Glide

Gliding also appears beyond land vertebrates. Some fish use the boundary between water and air, while some small invertebrates can control a fall through forest air. These examples stretch what people usually picture when they hear the phrase animals that glide.

Flying fish

Flying fish are ocean fish that launch themselves out of the water and hold enlarged fins open as gliding surfaces. Their movement begins with swimming speed underwater. Once airborne, the fins help them travel above the surface before they reenter the water.

A NOAA Education discussion of flying fish explains that flying fish appear to fly but actually glide after launching from the water. This distinction matters because flying fish do not flap like birds. Their glides are part of an escape and movement strategy shaped by water, air, and predators.

Gliding ants

Some canopy ants can control their descent after being knocked from a branch. Instead of falling straight to the ground, they can orient themselves and move toward a tree trunk. For a tiny insect living high in the rainforest canopy, returning to the tree can be much better than landing on the forest floor.

Gliding ants show that a glider does not need to be large or dramatic. Their movement is subtle compared with a colugo or flying fish, but the survival problem is similar: use air and body control to reach a better landing place.

What counts as gliding underwater

Most readers think of gliding in air, but biologists also discuss gliding phases in water. A swimming animal may stop active stroking and coast for a while, using body shape and momentum to continue moving. This is not the same visual image as a flying squirrel crossing a forest gap, but it belongs to the broader physics of moving through a fluid.

For this article, the main focus is aerial gliding, because that is what most people mean when they search for animals that glide. Still, underwater coasting helps show why gliding is about energy, lift, drag, and control, not just about animals with winglike membranes.

Common Myths About Gliding Animals

Gliding animals attract myths because their movement looks impossible at first glance. A squirrel that sails through the trees, a snake that seems to fly, or a fish that bursts from the ocean can easily turn into exaggerated claims. The truth is usually more interesting than the myth.

• Myth: Flying squirrels can fly like bats. They glide from higher to lower areas and cannot flap wings for powered flight.
• Myth: Sugar gliders are just tiny flying squirrels. Sugar gliders are marsupials, while flying squirrels are rodents. Their similar membranes are an example of unrelated animals arriving at a similar movement solution.
• Myth: Flying fish are birds of the sea. They are fish that launch from water and glide on enlarged fins.
• Myth: Flying snakes fall helplessly. Research has shown that they flatten and undulate their bodies, giving them more control than a simple fall.
• Myth: The best glider is simply the one with the longest distance. Accuracy, safe landing, turning, and habitat use can matter more than maximum range.

Edge Cases and Exceptions

The boundary between jumping, parachuting, gliding, and flight is not always sharp. Some animals mostly slow their fall with limited steering. Others can turn and aim with impressive control. Some birds and bats are powered flyers that also glide when they hold their wings out and descend. This means the word gliding can describe a behavior, not only a type of animal.

There is also a difference between common names and biological categories. The word flying appears in many animal names because the behavior looks like flight to human observers. That does not mean the animal uses powered flight. When reading about a flying frog, flying lizard, flying fish, or flying squirrel, it is usually safer to ask what the animal is actually doing with its body.

Another edge case is the animal that glides only at certain ages, in certain conditions, or in certain habitats. Wind, rain, height, body size, and landing surface can all affect whether gliding is possible or useful. A behavior that works in a tall rainforest may not work in a short shrubland or a fragmented urban tree line.

Why Height, Forests, and Landing Surfaces Matter

Gliding is tied to the shape of the environment. A glider needs a launch point, enough open space to spread and steer, and a landing surface it can grip or enter safely. That is why so many familiar gliding animals live in trees or move near vertical structures.

Climbing creates the launch

Many gliding animals are also excellent climbers. The climb gives them stored height, which becomes movement during the glide. Without a high perch, a flying squirrel or gliding lizard has little distance to work with. This connection between climbing and gliding is one reason claws, gripping toes, and balance are so important in many tree gliders.

Jumping starts the glide

A glide usually begins with a launch. The animal must commit to leaving the surface before the air-catching structures become useful. In mammals, that may mean springing from a branch. In flying fish, it means bursting through the water surface. In frogs and lizards, it often begins as a leap that becomes more controlled once the body spreads.

Open gaps can help or harm

Gliding animals benefit from gaps they can cross, but gaps that are too wide or exposed can be dangerous. Forest loss can change the distances between trees, reduce safe landing sites, and expose animals to predators or human hazards. Even when a species is not globally threatened, local habitat changes can make gliding less useful or more risky.

FAQ

What animal is the best glider?

It depends on what you mean by best. Colugos are often considered among the most specialized mammalian gliders because their membrane is so extensive. Flying squirrels are highly familiar and maneuverable tree gliders. Flying snakes are remarkable because they glide without limbs. Flying fish are exceptional because they move from water into air. Distance, control, landing accuracy, and habitat all matter.

Are flying squirrels the same as sugar gliders?

No. Flying squirrels are rodents, while sugar gliders are marsupials. They both use a gliding membrane, but they come from different mammal lineages. Their similarity is a good example of convergent evolution, which means unrelated animals can evolve similar features when they face similar movement challenges.

Can gliding animals fly upward?

Most gliding animals cannot climb upward through the air during a glide the way a bird or bat can during powered flight. They usually start higher and land lower. They may steer, slow down, turn, and choose a landing surface, but they are still trading height for horizontal travel.

Do any reptiles glide?

Yes. Flying dragons in the genus Draco glide with membranes supported by elongated ribs, and flying snakes in the genus Chrysopelea glide by flattening and undulating their bodies. These reptiles show that wings are not the only way to create controlled aerial movement.

Should people keep gliding animals as pets?

Some gliding animals, especially sugar gliders, are kept as exotic pets in some places, but that does not mean they are easy or appropriate for every household. They are nocturnal, social, active animals with specialized needs, and laws vary by location. Wild gliding animals should not be captured, handled, or disturbed.

Final Thoughts

Animals that glide show how many ways life can solve the same movement problem. A mammal can stretch a furry membrane, a lizard can spread rib-supported skin, a frog can use webbed feet, a snake can flatten and wave its body, and a fish can launch from water with enlarged fins. None of these animals needs true powered flight to move through the air with control. Gliding is a clever compromise: it turns height into distance, saves time in complex habitats, and helps animals move through worlds where climbing down or falling straight would be a poor choice.
