The Atlantic bluefin tuna is a torpedo-shaped predatory saltwater fish species. It is native to both the Western and Eastern Atlantic ocean, as well as the Mediterranean Sea. Fully grown specimens can reach a length of more than 10ft and a weight of more than 1000lb.
Both the Atlantic and Southern bluefin tuna are listed as endangered species with a currently decreasing population. Pacific bluefin tuna, on the other hand, are classified as vulnerable and have a slightly increasing population.
There is a population of them that has returned to the waters off the coasts of Sweden, Denmark and Norway. And the best thing is that their numbers are growing each and every year!
