The system acts as a counter-current heat exchanger and the heat from the blood in the veins is given up to the colder arterial blood rather than being lost at the gills. [1] It typically occurs from the surface to 200 m (660 ft),[5] but has been recorded as deep as 550 m (1,800 ft). In 2002, they succeeded in breeding them, and in 2007, the process was repeated for a third generation. Regarding their habitat, tuna fishs tend to live in warm waters, where the temperature ranges between 17° C to 33° C. Moreover, these fish are known for inhabiting in open sea. (2011).
