Asian Sheepshead Wrasse

Semicossyphus reticulatus

The Asian sheepshead wrasse (Semicossyphus reticulatus) is a large, unmistakable wrasse reaching up to 100 cm and 14 kg. Mature males develop a massively enlarged, bulbous forehead and prominent chin that give them a grotesque yet fascinating appearance. Found in the northwestern Pacific from Japan to Korea and China, it inhabits rocky reefs, kelp forests, and temperate coastal waters at depths of 5 to 30 meters. This protogynous hermaphrodite begins life as female and the dominant individual transforms into a large male. It feeds on shellfish, sea urchins, and crabs, crushing hard-shelled prey with powerful jaws. The species has gained worldwide attention through viral photographs of its extraordinary facial features. Divers in Japan particularly seek encounters with known individuals that have become local celebrities at dive sites.
