Spicules: Megascleres are tylostyles 280-(350)-430 µm densely and irregularly arranged. The heads have swellings just up from the tip in most spicules. Microscleres, are apparently normally absent; if present (this may indicate a related species), they are modified microrhabds (spiraster or amphiaster types derived from sanidasters).
