Tethyidae

Tethyidae is a family of marine sponges belonging to the class Demospongiae. These sponges are characterized by their tough, leathery texture and often irregular or massive shapes. They are commonly found in tropical and subtropical waters worldwide, inhabiting a variety of substrates including coral reefs, rocky shores, and the seabed. Tethyidae sponges are filter feeders, drawing water through numerous small pores called ostia and expelling it through larger oscula. Their skeletons are composed of spicules made of silica, which provide structural support. Some species within this family are known for their vibrant colors, while others are more subdued in appearance. Reproduction in Tethyidae can be both sexual and asexual, with larval stages often dispersing to new locations. The ecological role of Tethyidae sponges includes contributing to reef structure, providing habitat for small organisms, and playing a part in nutrient cycling within their marine environments. They are not typically considered commercially valuable for human consumption or use, though some scientific research may be conducted on their biology and chemical compounds.
