Thunnus
Tuna are several species of ocean-dwelling fish in the family Scombridae.
Tunas are fast swimmers and like most other fish species are cold-blooded. However, some of the larger tuna species such as the bluefin tuna can raise their blood temperature above the water temperature with muscular activity. Though not really warm-blooded, this enables them to live in cooler waters and survive a wider range of circumstances.
It is difficult to keep tuna in a captive environment; Monterey Bay Aquarium is one of the few aquariums in the world that successfully keep tuna in display.
Types include:
- bluefin tuna, which can grow to 1,500 pounds.
- yellow fin tuna
Tuna is a popular seafood, and in danger from overfishing.
Musician's saying (and a joke): You can tune a piano, but you can't tuna fish.
In Polynesian mythology, Tuna is the god of eels who was sentenced to be executed (by the Upolo) after trying to rape Sina (who had grown him in a jar). He asked that his head be buried in the sand and from it, the first coconut grew. He was Hina's lover.
