Fin whale

The finner, or fin whale, is a sleek giant of the ocean, second only to the blue whale in length. Its long, streamlined body is dressed in shades of gray with a lighter belly, helping it blend into the water when seen from below.

• Can grow up to 27 meters long—about the length of two school buses.
• Weighs as much as 120 tonnes, heavier than 20 elephants combined.
• Uses countershading to hide from predators and prey.
