The Fin Whale is the second largest whale on Earth. They are baleen whales and belong to a group of whales known as the rorquals (also includes Humpback Whales and Blue Whales) Fin Whales have long throat grooves that expand while they are feeding. Dark-gray in color, a distinguishing feature of the Fin Whale is the asymmetrical coloring of the lower jaw, which is white-pale yellow on the right side and mottled black on the left side.Fin Whale feed mainly on small shrimp-like creatures called krill or small schooling fish that get trapped in their baleen plates. They have earned the nickname β€œgreyhound of the sea” for being the fastest of the baleen whales and are capable of burst speeds up to 29 mph.Fin whales were a popular target for commercial whalers. Although the practice is currently banned, populations are still a small fraction of what they once were.
