Description
The body is usually a cup-like structure. In stalked forms the body can be mushroom-like. Spicules protruding beyond the sponge surface, when present, are diactines (spicules with two pointed arms) or specialised outwardly protruding hypodermal pentactines (five pointed spicules).[5]
The choanosomal skeleton consists of diactines, sometimes together with less frequent hexactines (spicules with six prongs). A large variety of microscleres occur in this family, including a variety of holactinoidal and asterous spicules.[5]
