Greasy grouper (Epinephelus tauvina) is a saltwater species recorded in Hong Kong, Taiwan, Malaysia. It is mainly found over reef, at depths of 1–300 m.
Scientific name: Epinephelus tauvina · Water: Saltwater
Size: up to 100 cm
Adult greasy grouper prefer clear-water coral reefs, while juveniles turn up on reef flats and in tide pools. It is usually solitary and remains common where fishing pressure is light. Fishes make up almost its entire diet, with crustaceans taken occasionally. Commonly about 90 cm and up to 100 cm, maturing at around 61 cm. A high-priced fish sold in Hong Kong live fish markets; IUCN lists it as Data Deficient. Note that most reports above 80 cm are probably misidentifications of larger relatives.
Caution: large individuals carry a ciguatera risk. Heat, cold and marinating do not remove the toxin, which concentrates in the liver, roe and head, so avoid eating those parts. Seek medical help if numbness, tingling or a reversed sense of hot and cold follows a meal.
