Ecology Summary - Cebidichthys violaceus

Language:

Main Ref.	Martin, K.L.M. and C.R. Bridges, 1999
Remarks	Common inshore, in tide pools or shallow rocky areas, from the intertidal zone to 24 m depth. May remain out of water under rocks or seaweed (Ref. 31184). Feeds mainly on crustaceans and algae. Breathes air (Ref. 31184) and can remain out of water for 15-35 hours if kept moist (Ref. 51276). At somewhere between 5 and 8 cm TL, they shift their diets and feed absolutely on algae, preferring reds and greens (Ref. 43439). 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).
