Iotrochota [Iotrochota]

Description

Iotrochota is a genus of marine sponges within the family Iotrochotidae. These sponges are characterized by their fibrous skeletons and the presence of both megascleres and microscleres, which are types of spicules that provide structural support. Members of this genus are typically found in a range of colors, including dark green, brown, and black. They are known to inhabit shallow tropical and subtropical waters, often growing on mangrove roots, rocks, and coral reefs. The surface of these sponges is usually rough, with a conulose (cone-shaped projections) texture, and they may have a branching or encrusting form. Iotrochota species play a role in their ecosystems by filtering water and providing habitat for small marine organisms.
