A little-known species of whale has been discovered off the coast of California.
The greenland whales, or greenland sharks, are believed to be the largest oceanic predator, weighing up to 6,000 pounds, according to a new study by the California Department of Fish and Wildlife.
The research was published Wednesday in the journal Current Biology.
The scientists say the greenland shark, which lives off the northern coast of the United States, is one of the largest species of whalewheel sharks in the world, weighing between 6,100 and 6,200 pounds.
Greenland sharks typically live in the deep ocean and can grow to between 8 and 16 feet long.
They are often mistaken for dolphins, but their eyes are not as large as those of dolphins.
