An equilibrium glide, achieving a constant airspeed and glide angle, is harder to obtain as animal size increases. Larger animals need to glide from much higher heights and longer distances to make it energetically beneficial. [9] Gliding is also very suitable for predator avoidance, allowing for controlled targeted landings to safer areas.

The Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, water gliders, water skimmers or puddle flies.
Flying fish with the biplane design take advantage of their high lift production abilities when launching from the water by utilizing a "taxiing glide" in which the hypocaudal lobe remains in the water to generate thrust even after the trunk clears the water's surface and the wings are opened with a small angle of attack for lift generation. [20]
At the end of a glide, they fold their pectoral fins to re-enter the sea, or drop their tails into the water to push against the water to lift for another glide, possibly changing direction. [14] [15] The curved profile of the "wing" is comparable to the aerodynamic shape of a bird wing. [16]
Various marine animals are capable of aerial locomotion, i.e., jumping out of the water and moving through air. Some possible reasons for this behavior are hunting, escaping from predators, and saving energy for swimming or breathing. Some of the jumping behaviors initiate gliding and taxiing in air, while some of them end up falling back to water.

They can travel as far as 70 m (230 ft) from one tree to another without losing much altitude, [10] with a Malayan colugo (Galeopterus variegatus) individual having been observed traveling about 150 m (490 ft) in one glide. [11] Their ability to glide is possible because of a large membrane of skin that extends between their paired limbs.
