Meet the Blue Whale – the largest animal ever recorded in Earth’s history. These gigantic creatures reach lengths of 80 to 105 feet – about as long as three school buses – and weigh up to 200 tons. Their tongue alone can weigh as much as an elephant!
Shockingly, Blue Whales reach this enormous size through a diet made nearly exclusively of tiny krill. Blue Whales are not predatory. Instead, they filter feed for krill, consuming around 4 tons in a single day. Needless to say they play an important role in their ecosystems.
Blue whales are found in all the world’s oceans except the Arctic. They are usually seen alone or in pairs, and occasionally in small groups.
In addition to being Earth’s largest animals, they are also among the longest living, with lifespans of approximately 80 to 90 years. And… they are some of earth’s the loudest animals! They communicate through pulses and groans that can be heard by other Blue Whales up to 1,000 miles away.
Commercial whaling in the 1900s almost drove this impressive species to extinction. Luckily, they became protected in the 1960’s… but their population was a small fraction of what it once had been, and it still hasn’t recovered.
Although they are protected today, Blue Whales are still vulnerable to human threats including vessel strikes, entanglements in fishing gear, and pollution.
Take action to protect the Blue Whale from extinction. Support regulations and organizations that foster whale-safe shipping practices and a healthy ocean habitat.
