There are four species of bluefin tuna, namely: Thunnus maccoyii, Thunnus orientalis, Thunnus thynnus, and Thunnus tonggol. Bluefin tuna are the biggest type of tuna. They can grow to over 3 meters in length and around 1,000 pounds in weight. Bluefin tuna are warm-blooded and can swim extremely fast. They can accelerate faster than the average sports car. The bluefin tuna live in colder climates. Characteristic of the bluefin is its blue streak just below the upper portion of its body, dark blue tail, and short pectoral fins.
Bluefin tuna are usually caught in the deep sea. This is the type of tuna which has the most amount of fat in its meat. Most species of the bluefin tuna are already classified as endangered due to the effects of overfishing. This is largely due to the growing demand of sushi all over the world. The meat of the bluefin tuna is considered the most expensive in the market. A type of sushi called Otoro is a highly desired part of the tuna belly. It is the part of the bluefin tuna with the most fat and comes at an incredibly high price.
Yellowfin tuna or Thunnus albacares is a species of tuna commonly found in the warm ocean waters. They are a widespread type of tuna. Yellowfin tuna are warm-blooded and really fast swimmers. They can grow to over 2 meters in length and 400 pounds in weight. The yellowfin tuna has a yellow color streak in the mid part of its body. This tuna has a long pectoral fin and yellow second dorsal fin. Its tail is a mix of yellow and gray.
Yellowfin tuna are caught in the open sea and usually at drop-offs. They have very lean meat and are considered relatively cheaper when sold in the market compared to the bluefin.
