Blue whales can grow up to 100 feet in length and 200 tons in weight, making them the largest animals on Earth, and the largest animals to ever exist. At birth, a blue whale calf is as large as an adult hippopotamus and can gain up to 200 pounds a day. When fully grown, blue whales are long and thin, with a small dorsal fin, two flippers at their side, and a horizontal tail, also known as a “fluke.” Blue whales are named for their bluish-gray coloring.
Blue whales are migratory and can be found in every ocean. They generally feed in colder polar regions and then head to warmer tropical waters to give birth. Blue whales usually travel alone or in pairs and communicate through a series of complex vocalizations. As a member of the rorqual (balaenopteridae) family, blue whales feed by straining their prey through bony plates in their mouths known as baleen. Their diet consists almost entirely of krill, a small crustacean similar to shrimp. They require 1.5 million kilocalories of energy every day and can eat up to 7,900 pounds of krill daily. Because of their speed and size, blue whales have practically no natural predators.
Blue whales were once widespread, with a population estimated in the hundreds of thousands. While they were initially too large and fast for whalers to capture, the invention of the harpoon gun in the late 1800s enabled whalers to successfully hunt blue whales. Decades of whaling followed, causing a significant population decline. An international ban on the hunting of blue whales was enacted in 1966, allowing their numbers to recover, although they remain endangered.
