Gazami crab, Asian blue crab, Horse crab
Portunus trituberculatus, also known as the gazami crab, Asian blue crab or horse crab, is the most widely fished species of crab in the world. It is found off the coasts of East Asia and is closely related to Portunus armatus.
The carapace may reach 15 centimetres (5.9 in) wide, and 7 cm (2.8 in) from front to back. P. trituberculatus may be distinguished from the closely related (and also widely fished) P. armatus by the number of broad teeth on the front of the carapace (three in P. trituberculatus, four in P. armatus) and on the inner margin of the merus (four in P. trituberculatus, three in P. armatus).
Portunus trituberculatus is found off the coasts of Korea, Japan, China, and Taiwan.
