Arrowhead Soapfish

Belonoperca chabanaudi

The Arrowhead Soapfish, known scientifically as Belonoperca chabanaudi, is a member of the Serranidae family, closely related to groupers. This species is found in the Indo-Pacific region, ranging from East Africa to Samoa, and extending north to the Ryukyu Islands and south to New Caledonia. It inhabits coral-rich areas, often on steep slopes, and is typically found at depths between 4 and 50 meters, though most are observed shallower than 40 meters. This fish is characterized by its elongated body, which is brown in color but can also appear dusky bluish-grey to almost black. It is easily identified by the large ocellated black spot on its spinous dorsal fin and a distinctive yellow spot on its caudal peduncle. The Arrowhead Soapfish is a secretive and solitary nocturnal predator, feeding primarily on small fishes and crustaceans. Divers may spot it hovering mid-water in caves, where it often goes unnoticed until its yellow spot catches the eye. The species produces a skin toxin known as grammistin, which is a characteristic of the soapfishes. Despite this, it is harmless to humans. The Arrowhead Soapfish is listed as Least Concern by the IUCN.
