Bermuda Post has collaborated with WWF issue the stamps featured Bluefin Tuna (Thunnus thynnus) on August 19, 2004. The cover has simple post mark and depict the school of fishes.
Thunnus thynnus or Northern bluefin tuna is native to both the western and eastern Atlantic Ocean, as well as the Mediterranean Sea. Northern bluefin tuna is a species of tuna in the Scombridae family and have become extinct in the Black Sea and Caspian Sea. The Northern bluefin tuna is a close relative of the other two bluefin tuna species—the Pacific bluefin tuna and the Southern bluefin tuna.
Throughout recorded history, the Northern bluefin tuna has been highly prized as a food fish. Bluefin have been a valuable commercial catch from the time of the ancient Greeks and Phoenicians to the modern era.This commercial importance has led to severe overfishing.
The body of the Northern bluefin tuna is rhomboidal in profile and robust. The head is conical and the mouth rather large. The colour is dark blue above and grey below with a gold coruscation covering the body and bright yellow caudal finlets. The Northern bluefin tuna can be distinguished by the relatively short length of their pectoral fins.
The Northern bluefin tuna can live for 30 years, but due to heavy fishing mortality, few known specimens grow to a mature age.The species can reach a maximum length of about 4.3 metres .The Northern bluefin tuna typically hunts small fish and invertebrates such as sardines, herring, mackerel, squid and crustaceans.
