Where does whales had/have their mammary gland?
Question Date: 2017-01-26
Answer 1:

Even though whales live underwater, they still manage to breastfeed. They’ve evolved things called “mammary slits”, which are special skin folds on the bottom of their abdomen, about 3/4 of the way to towards their tale. Scientists still aren’t sure exactly how the whales deliver the milk to the baby. The blue whale has the largest mammory glands on Earth- each one is about 1.5 meters long!!


Answer 2:

Whales and dolphins have mammary slits, which are special folds of the skin that surround the mammary glands to protect them. The mammary slits are on the belly-side of the whale near the tail.


Answer 3:

Whales have mammary glands in the same place as any other mammal, on the chest and stomach. I don't know how many nipples whales have, as the number is different in one kind of mammal from another (humans have two, bears have six, dogs I think have eight, and so on).


Answer 4:

Whales have mammary glands on their bellies (like other mammals) but they're towards the back of the animal near to the tail. However you can't really see them because they're hidden in mammary slits, and scientists still aren't sure exactly how baby whales feed from them.
