The only animals that can truly fly are birds, insects, and one type of mammal, which is of course the bat. Other animals manage to travel through the air by gliding from great heights, or leaping from the depths.

The mobula or devil ray is related to manta rays. They can grow up to 17 feet wide and ten feet long. These muscular fish can leap several feet out of the water, but no one is quite sure why they do it.

Flying lemurs of the family Cynocephalidae are neither true lemurs, nor do they actually fly. They are also known by their Malaysian name, colugos. These mammals live in southeast Asia and are about the size of a house cat. Colugos glide between trees using their patagium, or flaps of skin between their front and hind legs and extending to the tail and the neck. Colugos are even webbed between their toes. The flying lemur is not a lemur, but the four species of Cynocephalidae are the closest related family to primates.

There are about 50 different species of flying fish, although they don’t fly so much as they leap from the water with a push of their powerful pectoral fins. Most of the species live in tropical waters. Fish have been observed skipping over the waves for as long as 45 seconds at a time. Why do they leap into the air? Possibly because air offers less resistance than water, and the fish can move faster. At least until they need to breathe.

The flying snake (Chrysopelea paradisi) lives in the rain forests of Southeast Asia. It has no patagium, but glides from the treetops by flattening its body out to maximize surface area. The snakes slither from side to side to glide in the desired direction. The idea of a flying snake may be terrifying, but these snakes are officially classified as “harmless”.

The flying gecko lives in -you guessed it- the Malaysian rain forest. The gecko has a patagium that allows it to parachute or glide down from its treetop home. Flying geckos are sometimes kept as pets.

Wallace’s flying frog (Rhacophorus nigropalmatus) is found in Maysia and Indonesia, where it lives high in the treetops. This frog has long webbed toes and a skin flap between its limbs which allows it to parachute down from treetops. The term “parachute” in this case refers to the fact that the animal floats downward at a steep angle, while other “gliding” animals can float to one side or another and change direction while gliding downward. Although Wallace’s flying frog prefer to live high up, they must descend to near ground level to mate and to lay eggs. Photograph by Tim Laman.

Flying squirrels (Pteromyini) include 43 different species. They are native to North America, northern Europe, and Siberia. When they leap from a tall tree, a flying squirrel will spread its skin flaps until it resembles a kite or parachute. The squirrel can steer somewhat by moving its wrists and adjusting the tautness of its patagium.
There are more animals that can glide, float, or jump through the air with what seems like the greatest of ease. For this post, I restricted the list to those creatures who have the word “flying” in their common names.
“These muscular fish can leap several feet out of the water, but no one is quite sure why they do it.”
Why they do it? If you could do it, wouldn’t you?

I think I could handle any of these but the flying snake…yikes!

There is no such thing as a harmless flying snake!

“Harmless flying snake” is definitely an oxymoron. If I saw a snake flying through the air, I would have a heart attack.

I’m with the others. A flying snake is terrifying – and would certainly cause me bodily harm just by witnessing the act.
This will likely bother me all day.

“Why they do it? If you could do it, wouldn’t you?”
Well put.

There are fish that actually fly by flapping in the air, and you can buy them, though you’ll need a top on your tank….

hmm, the web site didn’t paste in. Mush have misunderstood the purpose of the box. Nothing to flap about, I’ll paste it here: http://animal-world.com/encyclo/fresh/characins/hatchet.php

“These muscular fish can leap several feet out of the water, but no one is quite sure why they do it.”
…and just under the water are a bunch of senior Devil Rays, playing dominoes and drinking lemonade, complaining about how those d@mn youngsters are recklessly flying out of the water and making too much noise.
Good Post!

ahhh..One of those flying lemur things got into my house..he’s holding me hostage with a knife in his wingy arm.

“Possibly because air offers less resistance than water, and the fish can move faster. At least until they need to breathe.”
Fish can breathe fine in air, but prolonged stay out of water will cause their gills to collapse under their own weight, and the fish will die cause of that.

Squirrels creep me out just scurrying around like they do, so that furry rhombus flying towards me? Crikies!
“…adjusting the tautness of its patagium”.
Thank you for that. :)
I’ll try to use it in a sentence tomorrow.

What of the pteropus or, as it is commonly known, the flying fox? They’re twice as adorable as the flying lemur!

That’s not flying, it’s falling, with style!

A flying snake. That is too much for anyone to handle.
And why is everything flying in Southeast Asia… Whats evolution got brewing over there?
As for the mobula, that sucker looks ready to kill… Thats why he does it.

The Mobula flies to get away from the flying sharks, who in turn are getting the hell out of the way of the flying bears!

Mike B, the pteropus is a bat, which is a whole ‘nother post.

@ee the c: Watch me pull a rabbit out of my hat, indeed. :D
As for the flying gecko, dare I break out my best little orphan impression and exclaim, “Leapin’ lizards!”
