Blackspot tuskfish

The blackspot tuskfish (Choerodon schoenleinii) is a wrasse native to the Indian Ocean and the western Pacific Ocean from Mauritius to Indonesia and Australia north to the Ryukyu Islands.

It can reach 100 cm (39 in) in TL, and the greatest published weight for this species is 15.5 kg (34 lb).

It is popular as a game fish, in particular with spearfishers, and can be found in the aquarium trade.

In Hong Kong, its Cantonese name, tsing yi (Cantonese:青衣), has been given to an island (see Tsing Yi).The fish is named in honor of Johann Lucas Schönlein (1793-1864), the German naturalist and professor of medicine.

[3] In July 2011, a professional diver photographed a blackspot tuskfish bashing a clam on a rock to break the shell, apparently a use of the rock as a tool, the first documented example of tool use in wild fish.

Blackspot tuskfish being sold as food while still alive in a market on Tsing Yi, the island mentioned in the text above. However, the fish are unlikely to be caught near the island, as the current marine environment around the island is too poor for them to live in because of urban development.
