A toddler can fit into a blue whale’s blowhole. The spray can reach up to 30 feet high. The blue whale’s scientific name is Balaenoptera musculus. Blue whales live in all oceans of the world. A blue whale’s tongue weighs more than an elephant. Blue whales are the loudest animal on Earth reaching up to […]
