Invertebrates have a hard outer shell, called an exoskeleton. Muscles are attached to the inside of the exoskeleton, and contraction of these flexes the joints.
It depends on what animal it is. A jellyfish, for instance, moves by swaying its body back and forth. A caterpillar uses its small legs to move.
I hope this helped... :D
All animals breathe. Even those which live underwater.
But not all animals breathe in the same way. It depends on the species.
Sponges, flatworms, roundworms and other simple invertebrates breathe through diffusion.
Other invertebrates, like aquatic worms and mollusca, have gills. Starfish get their oxygen through a water vascular system.
They are generally ambulatory. They move on jointed legs and have anywhere from 6-10 of them.
arthropods move easily and quickly because they have jointed legs.
