Grantia [Grantia]

Description

Grantia is a genus of marine sponges within the family Grantiidae. These sponges are characterized by their tubular or branching shapes, often forming clusters that resemble small bushes. They are filter feeders, trapping particles from the water that flows through their bodies. The surface of Grantia sponges is covered with spicules, which are microscopic needle-like structures providing support and protection. These sponges are found in a variety of marine environments, from shallow coastal waters to deeper oceanic regions, and play a role in the marine ecosystem by filtering water and providing habitats for other small organisms.
