A Japanese restaurateur at Japan’s Tsukiji fish market has paid nearly three-quarters of a million dollars for a single tuna.

(This is the most ever paid for this endangered species; bluefin tuna. The beautiful animal weighed 269-kilogramme (592-pound), which means it cost a whopping 210,000 yen per kilogramme. It was caught off the coast of Japan’s northern Aomori prefecture. Japan consumes three-quarters of the global catch of bluefin, a highly prized sushi ingredient known in Japan as “kuro maguro” (black tuna) and dubbed by sushi connoisseurs the “black diamond” because of its scarcity. Of course tuna is often loaded with mercury and a mix of nasty industrial chemicals such as dioxins, pesticides and PCBs, which have been dumped in our seas and oceans, and with the risk of contamination from the nuclear waste swept away in the Tsunami, this fish may have the last laugh.)
