The largest animal to have ever lived on our planet is none other than the Blue Whale.
These Baleen whales grow up to 30 meters in length, and weigh up to 200 tons!! Its tongue alone can weigh 3 tons, and a newborn calf is as heavy as an adult Hippopotamus!
Scientists estimate Blue Whales can live for up to 80 years, although they are still vulnerable to climate change, vessel strikes, and their only known predator, the Orca.
Surviving a near extinction during the 19th century, Blue Whales have since been recovering, with populations estimated at more than 12,000.
