Keratosa, the keratose sponges or horny sponges, is a subclass of demosponges.[2]

Keratosa sponges are nonspicular demosponges with organic spongin fibers forming flexible skeletons. [3][4]

Recently discovered in the Andaman and Nicobar Islands, these sponges contribute to reef structures in tropical regions. [5]
