Description

A large number of sponges are very difficult to identify to individual species. These sponges share a similar form and grow over the surface of rocks, and can even grow on the shells of slow moving animals like abalone.

Sponge skeletons often remain when the animals die and wash up on the beach. Sponges are generally toxic to most animals but some nudibranchs eat them. Sponges filter plankton from the water.
