Plakinidae [Plakinidae]

Description

Plakinidae is a family of sponges within the order Homosclerophorida. Members of this family are characterized by their encrusting habit and the presence of siliceous spicules, which are unique skeletal elements that provide support and protection. These sponges are found in a variety of marine environments, from shallow waters to the deep sea. Plakinidae sponges are notable for their contribution to the benthic ecosystem, participating in the cycling of nutrients and serving as a habitat for other marine organisms. Their morphological and genetic diversity makes them an important group for studies on sponge evolution and ecology.
