Biologi     Ordlista (t.ex. epibenthic)

Found solitary in abandoned tubes (Ref. 90102). Inhabit clear lagoon and seaward reefs with mixed corals and algae-covered rocks. Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
