The giant damselfish (Microspathodon dorsalis) is a species of fish that inhabits rocky reefs below the surf zone at depths of 1–25 m. It mainly feeds on low-profile, attached algae. Giant damselfish defend both feeding and reproductive territories by driving off other fishes and divers who come too close.
