The body structure of a sponge is mostly a spongy skin that is jelly like. The outer layer of this skin is bombarded with pores, which it uses to filter feed. In the filter feeding process, it eats the tiny plankton and other organisms that live under the ocean. It has a large cavity inside of the sponges skin where in reproduction, the sponge stores the sperm and egg cells to make the sponge larvae. The larvae then swims out of the sponge using its newly developed flagella and lands safely somewhere on the bottom of the ocean, where eventually, this sponge will grow to be an adult.
Sponges protect themselves with spikes in their body.
