Equipped with teeth, speed and a constant need for nourishment, Atlantic bluefin tuna are constantly looking for food. One reason their appetites are so insatiable is their unusual circulatory system. Tuna, unlike other fish, are warm blooded.

What tuna has big teeth?

The dogtooth tuna is aptly named for its 40, dog-like teeth, and is actually a member of the mackerel family. They have streamlined, torpedo-like bodies, with a large head and mouth at the end where their canine teeth are – 20 per jaw to be exact!

Can tuna eat humans?

What about humans? Extremely unlikely. First of all because they normally feed in shoals, groups of 20, 30, 40, 50 different fish that all vary in size. And they generally follow herring, anchovy or sardine shoals themselves, where they can maximize their feeding.
