Fin whale

The fin whale, also known as the common rorqual, is the second-largest animal on Earth, after the blue whale. It can reach lengths of up to 85 feet and weigh as much as 80 tons. Found in oceans worldwide, fin whales are filter feeders that primarily eat small fish and krill by taking in huge volumes of water and then filtering out their food. They are sleek, fast swimmers, reaching speeds of around 20 miles per hour, and are known for their distinctive, rapid breathing breaches at the surface. Fin whales play a vital role in marine ecosystems by helping regulate plankton populations.
