some animals such as clams have hard shells to protect them. sometimes if a predator sees a sheel it will either think it's a rock, but even if they dont think its a rock they will struggle to get the clam out of the shell even though some animals are able to.

It’s call a skeleton ahhhh I sorry I tried to be funny but failed yaa don’t be like me.
Limestone is a rock that is formed from the skeletal remains of sea animals and plants. It is primarily composed of calcium carbonate, which is derived from the shells and skeletons of marine organisms such as coral, mollusks, and foraminifera. Over time, these remains accumulate and become compacted and cemented to form limestone rock.
Shells protect prey from pretador.
