Coelenterates locomote with the help of tentacles.

The inner muscular part of epitheliomuscular cells is provided with contractile fibrils.

Macrophages and leukocytes move by pseudopodial movement.

Organisms which cannot move are called sessile organisms. They remain fixed at a place.

Paramecium is surrounded by numerous minute cilia on the body which help in movement.

Hydra somersaults like an acrobat with the help of tentacles.

Starfish have developed water vascular system for locomotion.

Pseudopodial movement is exhibited only by unicellular organisms and all insects are multicellular.

Leech and earthworm perform crawling or looping movement with the help of contraction and relaxation of circular and longitudinal muscles.

Movement of sperms is by flagella, which is a non-muscular movement.

Tube feet attach to the substrate by vacuum action of suckers.

Euglena moves with the help of flagella, i.e. it shows flagellar movement.

Starfish have tube feet as the locomotory organ.

Octopus has muscular arms for locomotion.

Uterine wall is inside the body and its contraction is an example of internal organ movement.
