Pacific Mutton Hamlet

Alphestes immaculatus

The Pacific Mutton Hamlet is a marine ray-finned fish within the grouper family, easily identified by its compressed, deep body, large eyes, and short snout. Its body exhibits a marbled reddish-brown color with faint bars and numerous dark and light spots, offering effective camouflage. The pectoral fins display 7 or 8 irregular horizontal rows of small dark spots. Typically, these fish grow to about 18 cm, although they can reach a maximum length of 30 cm. This species is found in the Eastern Pacific Ocean, from southern Baja California to Peru, including the Galápagos Islands. It inhabits shallow waters, favoring seagrass beds and rocky reefs at depths ranging from 1 to 50 meters. The Pacific Mutton Hamlet is a solitary and secretive fish, often seen hiding among rocks or seaweed during daylight hours. At night, it becomes active, hunting for benthic invertebrates and small fish. Divers might spot this elusive fish resting among rocks or partially buried in sand during the day. Although not targeted by commercial fisheries, it is sometimes caught by artisanal fishers. The Pacific Mutton Hamlet is currently classified as Least Concern in terms of conservation status.
