Spongin, a modified type of collagen protein, forms the fibrous skeleton of most organisms among the phylum Porifera, the sponges. It is secreted by sponge cells known as spongocytes.
Spongin gives a sponge its flexibility. True spongin is found only in members of the class Demospongiae. Its molecular structure remains incompletely characterized, however it shares similarities with both collagen and keratin.
