The common name for “Thunnus thynnus,” is bluefin tuna. It includes three of the eight species: the southern bluefin tuna (Thunnus maccoyii), northern bluefin tuna (Thunnus thynnus), also known as the Atlantic bluefin tuna, and the Pacific bluefin tuna (Thunnus orientalis). The scientific classification of the Bluefin is: Animaila (Kingdom), Chordata (Phylum), Actinopterygii (Class), Perciformes (Order), Scombridae (Family), and Thunnus (Genus).
The size of the bluefin tuna is usually three meters in length, but sometimes can reach up to four meters in length. The average weight for a Bluefin tuna is around 130 kilograms to 680 kilograms, which is 286.6 pounds to 1499.14 pounds. The Bluefin tuna has

Bluefin tuna eat other fish such as mollusks, crustaceans, and macro algae. Sharks and giant marine animals prey on the bluefin tuna itself. Up to 72 parasites also host on the bluefin tuna. Farming the bluefin tuna with chemicals can also impact the environment. Removing bluefin before spawning affects the ratio of offspring. The bluefin tuna reproduces by spawning their eggs. The pacific bluefin tuna lay eggs in the Western Pacific ocean. The Atlantic bluefin reproduce in the Gulf of Mexico and the Mediterranean in the west. After the bluefin tuna lay their eggs, they do not look out for them. It takes four to eight years for bluefin tuna to become sexually matured. The bluefin tuna can live up to an estimated thirty to forty years, but many bluefin tuna are captured before they have the chance to mature. The bluefin tuna can produce large amounts of eggs per year. The chance of survival for each egg, however, is 1 in 40 million. The northern and southern Bluefin tuna are critically endangered. The bluefin tuna has been exploited since recorded history began. The population is decreasing from the demand for Bluefin tunas in high end sushi markets. It is a prized fish to eat. Many chefs, mainly in Japan, buy them for a large amount of money. Also, illegal capturing of the bluefin tuna is a huge issue and illegal fishing has not been controlled and constrained well. The market for canned tuna after 1960 removed a lot of bluefin tuna from the population. Although there is not an exact number of bluefin tuna left, there is a very small amount left in the world. According to research, overfishing caused the Pacific bluefin tuna numbers to drop 96 percent. Fishing fleets from the United States, Mexico, South Korea and Japan are the main countries exploiting the bluefin tuna
