The Humpback whale best

Out in the big blue ocean, whales spend their lives swimming around under water. However as mammals, they have to come up to the surface to breathe. To help with this, their nostrils have moved onto the top of their blowhole can be as high as a house. Baleen whales, such as Humpback whales, don't have teeth. Instead they have long bristles called baleen, which filters small fish and shrimp from the water like a kitchen strainer. Their huge babies drink milk, though. A new born calf drinks enough milk every day to fill a best bath tub!
