生物學特性     字彙 (例如 epibenthic)

Facultative air-breathing (Ref. 126274); Adults occur in tide pools and close to edge of rocky shores at low tide. 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).
