Bluefin tuna is an adoptable animal in Zoo Tycoon: Marine Mania. Atlantic bluefin tuna reach maturity relatively quickly. In a survey that included specimens up to 2.55 m (8.4 ft) in length and 247 kg (545 lb) in weight, none was believed to be older than 15 years. However, very large specimens may be up to 50 years old.
The bluefin possesses enormous muscular strength, which it channels through a pair of tendons to its lunate shaped caudal fin for propulsion. In contrast to many other fish, the body stays rigid while the tail flicks back and forth, increasing stroke efficiency.
