Biologie     Verklarende woordenlijst (bv. epibenthic)

Adults inhabit rocky boulders from depths of 2 to 5 m, common at depths less than 10 m (Ref. 6211). They live in small groups, each comprising a male and several females (Ref. 48636) on rock surfaces and under ledges and tidepools (Ref. 75031). 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).
