HOW DO WHALES BREATH?


A whale's "nostrils" are called blowholes and are on the top of its head. Some whales have one blowhole and others, like this blue whale, have two. Unlike humans, whales breathe voluntarily. That means they choose when to take a breath. This is important because whales can't breathe underwater. They surface every few minutes to blow out a mixture of water and air and take in a breath of fresh air.
