Diagnosis

Sponges primarily in alpha growth form (excavating chambers, communicating through papillae), some species developing beta stage by merging of papillae, very few regularly outgrowing their substratum and occurring in gamma stage. Some gammastage species attain large, irregular massive or cup shape but do not develop specialised incurrent or excurrent features other than, in some forms, the original pori- and oscula-bearing papillae. Spicules are tylostyles as megascleres, very thin oxeas (raphides) as accessory scleres but never of structural importance, and spiraster-like microscleres. Spirasters are straight, bent, kinked, spiraled, or undulate spiny rhabds, including amphiastrose forms clearly derived from true spirasters; extreme forms may be entirely smooth.
