Blue Whales are the largest known animal in the world; growing up to 98 feet (30 meters) and weighing up to 173 tons (157,000 kgs). They can be found living in the North Atlantic, North Pacific and parts of the Southern Hemisphere. Just like their name, Blue Whales have a long-tapered body and have a bluish-grey dorsal. Blue whales don’t have teeth, but instead have large baleen which help separate sea water from krill after they swallow. After separation, the water is shot out their blowhole when they come up from water.
The typical Blue Whale has an overall height of 13’-16’ (3.96-4.88 m) and body length of 82’-105’ (25-32 m). An average Blue Whale weighs between 55-165 tons (50-150 metric tons) and has a typical lifespan of 80-90 years.
