There are many vertebrates such as arthropods, mollusks and sponges, which all have a hard-outer shell to protect their soft bodies. For the duration of their life, sponges inhabit only one location. Significantly, mollusks have an organ to help them eat algae off of rocks. Protecting itself, arthropods have shells that shed when they become too tight.
Arthropods are creepy crawling bugs which there are over a million-different species. Because of their vast numbers, they are considered one of the most successful species.
