Habitat!
Sponges can be found in almost all water habitats. Although most reside in marine bodies of water, up to 150 different species of sponges have adapted to freshwater climates. Many sponges contain a toxic substance to discourage predators and so other marine animals protect themselves by attatching a sponge to their body where it can grow.
