The Largest Animal on Earth

The Blue Whale

The blue whale (Balaenoptera musculus) is the largest animal on Earth, both in terms of length and weight. It is also the largest animal that has ever lived. Blue whales can grow up to 100 feet long and weigh over 200 tons. They are about the size of three school buses!

Blue whales are found in all the world's oceans, but they prefer the cold waters of the Arctic and Antarctic. They are filter feeders, meaning they eat small animals called krill. Blue whales can eat up to 4 tons of krill per day!

Blue whales are endangered, and their population is estimated to be around 20,000. The main threats to blue whales are hunting, ship strikes, and habitat loss. However, there are many conservation efforts underway to protect these amazing animals.
