Some modes of locomotion are (initially) self - propelled, e.g., running, swimming, jumping, flying, hopping, 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). </P> <P> 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 . </P>

Movement of an animal species from one place to another is called
