WebDiagram of a section through part of a sponge with a fibrous skeleton. A sponge is a member of the phylum Porifera. Sponges are aquatic invertebrates; some inhabit freshwater but the vast majority of the 9,000 or so species known to science live in a marine environment. All are permanently attached to rocks or other surfaces. WebVarious cell types reside within the mesohyl, including amoebocytes, the “stem cells” of sponges, and sclerocytes, which produce skeletal materials. The gel-like consistency of mesohyl acts like an endoskeleton and maintains the tubular morphology of sponges. The feeding chambers inside the sponge are lined by choanocytes (“collar cells”).
