The skeleton of the sponge is composed of tiny needle-like splinters called spicules, a mesh of protein called spongin, or a combination of both. Many sponges can only be identified by microscopic examination of the skeleton, which makes certain identification from photographs difficult.he collar cells have a sticky, funnel shaped collar and a hairlike whip, called a flagellum. The collar cells serve two purposes. First, they beat their flagella back and forth to force water through the sponge. The water brings in nutrients and oxygen, while it carries out waste and carbon dioxide.
reproduction by sponges is by both sexual and asexual means asexual reproduction is by means of external buds some species also form internal buds called gemmules which can survive extremely unfavorable conditions that cause the rest of the sponge to die sexual reproduction takes place in the mesohylther characteristics of sponges include a system of pores also called ostia and canals through which water passes water movement is driven by the beating of flagellae which are located on specialized cells called choanocytes collar cells
