Which organism move using jointed appendages?
Insects
A jointed appendage is a characteristic feature of insects. Snails move by gliding along on their muscular foot, which is lubricated with mucus and covered with epithelial cilia. The earthworm's body is divided into segments. Each segment has a number of setae or very small bristles that earthworms use to help them grip the soil as they move. An earthworm moves by using two different sets of muscles. Amoeboid movement is the most common mode of locomotion in eukaryotic cells. It is a crawling-like type of movement accomplished by protrusion of cytoplasm of the cell involving the formation of pseudopodia ("false feet") and posterior uropods.
