Fun Facts about Blue Whale
Blue whales are the largest animals and among the loudest creatures on the planet. Their sounds can be heard from miles away.
A blue whale's tongue alone can weigh as much as an elephant, and its heart can be as large as a car.
Blue whales feed by opening their mouths wide and swimming through large groups of krill, filtering out the tiny crustaceans using baleen plates in their mouths.
Blue whales have enormous hearts, and their heartbeat's low-frequency sound can be detected from a distance of more than 2 miles.
