Animal locomotion
Animal locomotion, in ethology, is any of a variety of movements that results in progression from one place to another. Some modes of locomotion are (initially) self-propelled, e.g. running, swimming, jumping, flying, soaring and gliding. There are also many animal species that depend on their environment for transportation, a type of mobility called passive locomotion, e.g. sailing (some jellyfish), kiting (spiders) and rolling (some beetles and spiders).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. 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.
