Gray Crellid [Crellastrina]

Description

Crellastrina is a genus within the family Crellidae, distinguished by its typically gray or muted coloration, though colors can vary among species. These sponges have a compact, often encrusting form, and they are found in a variety of marine settings, including rocky substrates and coral reefs. The surface of Crellastrina sponges is smooth to the touch, and their internal structure is supported by a combination of spongin fibers and mineral spicules. These sponges are filter feeders, playing a role in the marine ecosystem by filtering water to capture food particles.
