That’s right, humpback whales, like all whales, are mammals, not fish. The whale is actually the closest living relative of the hippo, believe it or not! Wouldn’t that be an interesting family reunion! About 50 to 60 million years ago, some land mammals wandered off into the ocean, decided they liked it there, and eventually evolved into marine mammals, including the humpback whale! Like all mammals, whales breathe air through a pair of lungs, are warm blooded, and give birth to live young who drink milk.
How does nursing work underwater, you might ask? Well, whale milk is super high in fat, with a toothpaste like consistency. This allows it to travel through the water without breaking up too much. When baby is hungry, mom pretty much shoots the milk straight into its mouth! A baby humpback may drink up to 150 gallons of milk a day! And by way, the waters around Cabo San Lucas serve as a humpback nursery, so come join us on a whale watching tour for a chance to check out these hungry baby guzzlers yourself!
