Thunnus is a genus of ocean-dwelling fish in the family Scombridae, all of which are tuna, although other tuna species are found in other genera. The name of the genus is the Latinized form of the Greek θύννος, thýnnos, tuna, the word being first mentioned in Homer[citation needed]. Due to overfishing the genus range has been significantly reduced, being effectively removed from the Caspian Sea, for example.
Their coloring, metallic blue on top and shimmering silver-white on the bottom, helps camouflage them from above and below.
They can grow to 15 feet long and weigh over 1,000 pounds. They can swim up to 50 miles per hour when pursuing prey.
