Movement or no movement: motive or sessile?

Any animal that moves is motive.

Any animal that is attached to something and can only move part of its body is sessile.

snakes slither – they are motive

Motive animals can fly, walk, swim, crawl, hop, slide, slither, glide, and jump.

This is called locomotion. Loco means from a place, and motion means movement, so locomotion means movement from a place.

To move, animals have legs, wings, fins, tails, tentacles, or some other means for moving their bodies.

Sessile animals are attached to an object and can only move parts of their bodies.

Sessile animals are usually aquatic (water) animals, such as barnacles, sponges, hydra, and corals.
