This surface locomotion takes advantage of the surface tension of water.Animals that move in such a way include the water strider.A stomatopod, Nannosquilla decemspinosa, can escape by rolling itself into a self-propelled wheel and somersault backwards at a speed of 72 rpm.

Velella sails always align along the direction of the wind where the sail may act as an aerofoil, so that the animals tend to sail downwind at a small angle to the wind.
While larger animals such as ducks can move on water by floating, some small animals move across it without breaking through the surface.
For example, migratory animals that travel vast distances (such as the Arctic tern) typically have a locomotion mechanism that costs very little energy per unit distance, whereas non-migratory animals that must frequently move quickly to escape predators are likely to have energetically costly, but very fast, locomotion.
The anatomical structures that animals use for movement, including cilia, legs, wings, arms, fins, or tails are sometimes referred to as locomotory organs Animals move through, or on, four types of environment: aquatic (in or on water), terrestrial (on ground or other surface, including arboreal, or tree-dwelling), fossorial (underground), and aerial (in the air).
Animals move for a variety of reasons, such as to find food, a mate, a suitable microhabitat, or to escape predators.
For many animals, the ability to move is essential for survival and, as a result, natural selection has shaped the locomotion methods and mechanisms used by moving organisms.
Water striders have legs that are hydrophobic, preventing them from interfering with the structure of water. The female, above, is in fast forward flight with a small angle of attack; the male, below, is twisting his wings sharply upward to gain lift and fly up towards the female. Because it is impossible for any organism to have a density as low as that of air, flying animals must generate enough lift to ascend and remain airborne.
One way to achieve this is with wings, which when moved through the air generate an upward lift force on the animal's body.
Gliding is heavier-than-air flight without the use of thrust; the term "volplaning" also refers to this mode of flight in animals.
This mode of flight involves flying a greater distance horizontally than vertically and therefore can be distinguished from a simple descent like a parachute.
