Common name: Acarnid Sponges
Scientific name: Acarnidae
Acarnidae is a family of sponges found in marine environments. These sponges are characterized by their lack of a true skeleton, instead possessing a mesh of spongin fibers. They are often encrusting or massive in form and can be found in a variety of colors. Acarnid sponges host a range of microorganisms, making them important in nutrient cycling in reef ecosystems. They are not commonly kept in home aquariums due to their specific care requirements and slow growth rates.
