Ecology Summary - Scartichthys viridis

Language:

Main Ref.	Stepien, C.A., 1990
Remarks	Found in tide pools and rocky shore areas. Is primarily herbivorous (Ref. 9032). Feeds mainly on macroalgae, tiny invertebrates usually live in association with turf macroalgae contributed little to the diet (Ref. 50629). The sheet-like green macroalgae Ulva and Enteromorpha were the main items consumed by individuals <13 cm TL while the tough branching red macroalga Gelidium made the bulk of the gut contents of fish >22 cm (Ref. 36299). Large individuals possessed longer guts relative to their body length in comparison with small individuals (Ref. 36299).
