Notas | Found in rocky areas, from intertidal to 18 m depth, mostly on exposed coast (Ref. 2850). May remain out of water under rocks or seaweed (Ref. 31184). Feeds mainly on algae (Ref. 6885). Juveniles were zooplanktivores and adults are primarily herbivorous (Ref. 41810). Predation by early juvenile fishes on water-column planktors was greatest following initial intertidal settlement and habitat establishment (Ref. 41810). Greater dependence on substrate-oriented and/or benthic prey was exhibited as the fish grew in size (Ref. 41810). Breathes air (Ref. 31184) and can stay out of water for 17-23 hours if kept moist (Ref. 51276). |
