生物学特性     字汇 (例如 epibenthic)

Adults are found among rocky boulders and in surge channels to a depth of about 6 m (Ref. 9849). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).

发现于岩石的大圆石中了与在汹涌的峡道到深度大约 6 公尺中。
