Diagnosis

Hadromerida with limestone-excavating capability, having tylostyles as principal megascleres, in some genera accompanied by oxeas or styloid modifications. Microscleres may be absent entirely or in some specimens or populations. If present, they include spirasters, amphiasters, microxeas, microrhabds, or raphides; some spirasters display secondary branching of spines, microrhabds may be smooth or microspined, straight, bent, or spiral.

ID Keys

KEY TO GENERA
(1) Sponges excavating chambers in limestone substrates, with ostial and oscular papillae remaining at the surface (alpha stage), or forming continuous encrustations (beta stage), or masses (gamma stage) that grow beyond the original substrate piece; without specialized aquiferous structures except, in some species, the original papillae --- 2
Sponges massive, without endolithic chambering in the adults, with specialized aquiferous morphology -------------- 7

(2) Spicules include oxeas --------------------------------------------------------------------------------------------------------- 3
Spicules do not include oxeas ----------------------------------------------------------------------------------------------------- 5

(3) Oxeas are spiny microxeas, located in the chambers (criss-cross fashion), and are accompanied by straight or sinuous spiny microrhabds -------------------------------------------------------------------------------------------------- Pione
Oxeas are smooth and form a palisade in the papillae ------------------------------------------------------------------------ 4

(4) Spiculation is restricted to tylostyles and oxeas, no microscleres ----------------------------------------------- Volzia
Spiculation includes spirasters in addition to tylostyles and oxeas ------------------------------------------- Clionaopsis

(5) Microscleres are raphides or spirasters, or missing altogether; spirasters may include diplastrose modifications or have lost spines entirely (sinuous microstrongyles) ------------------------------------------------------------------- Cliona
Microscleres are amphiasters or euasters ------------------------------------------------------------------------------------- 6

(6) Microscleres are two types of amphiasters: stout, smooth, nodulose, and thin-rayed with terminal branching ---------------------------------------------------------------------------------------------------------------------------- Cliothosa
Microscleres are microspined amphiasters and smooth, thin-rayed oxyasters ----------------------------------- Thoosa

(7) Sponges irregularly massive, with cribiporal chones and simple but often multiple oscula ------ Spheciospongia
Sponges form large, branched, antler-like inhalant fistules and amorphous endopsammic masses with
exhalant stolons ----------------------------------------------------------------------------------------------------- Cervicornia
