Instead of drinking water, they can use the water and other liquids in the fish that they eat. The Fin whale, also known as Finback whale, is the second largest animal to live on earth. This whale is usually solitary, spending most of its time by itself, but is occasionally seen in the company of another fin whale or pod of dolphins. They have baleen instead of teeth, and like to eat krill and herring. Fin whales are the loudest animal on earth.
Fin whales make the loudest sounds of any animal on earth.
These sounds are five to ten times louder than the sound made by a jet taking off. The sounds are of a very low frequency that is below the human hearing range, but we could feel the vibration of the sound in the water. Fin whales can use these sounds to communicate over very large distances. Minke whales are baleen whales. Instead of teeth inside their mouth, Minkes have 300 plates of baleen.
