📖 Overview

Facultative air-breathing in the genus ; Adults are abundant on rocky reefs from 10 to 25m, recorded from 2 to 33m . They occur in low tide pools and subtidal areas and prefer overhangs and holes containing sponges and bryozoans . Juveniles are found in shallow waters, while adults are more abundant in deeper waters. They feed mainly on crustaceans and small gastropods . Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites . Larvae are planktonic which occur primarily in shallow, nearshore waters .
