About Pacific Bluefin Tuna
- Pacific Bluefin Tuna (Thunnus orientalis) is a predatory species of tuna found widely in the northern Pacific Ocean.
- They are predatory and mainly eat squids and fish, such as sardines and anchovies, saury, herring, pompano, mackerel, hake, other tunas, and occasionally red crabs and krill.
- They have black or dark blue dorsal sides, with a greyish-green iridescence.
- Their bellies are dotted with silver or grey spots or bands.
- They have a series of small yellow fins, edged in black, running from the second dorsal fin to the tail.
- They have relatively small eyes compared to other species of tuna.
- Most of the U.S. catch of Pacific bluefin tuna is within about 100 nautical miles of the California coast.
