sponginsecreting
Sponginsecreting is the biological process by which some sponges synthesize and secrete spongin, a soft, fibrous protein that forms part of their skeleton. Spongin-based skeletons confer elasticity and resilience, helping sponges withstand water movement while maintaining their filter-feeding structures.
The secretion of spongin occurs in specialized mesohyl cells called spongocytes (also known as sponginocytes). These
Patterns of sponginsecreting vary among sponge groups and are influenced by developmental stage, habitat, and environmental
Human relevance arises from the fact that many commercially exploited bath sponges derive from spongin-rich species.
