MICROANATOMY

Detailed explanation-1: -To be more hydrodynamic, the mother’s nipples are inverted at the mammary gland until the baby starts to nudge where they then start to point out. The mom then starts to shoot out milk. Whales don’t have lips, so they can’t really suckle the milk. Instead it’s almost injected into the baby’s mouth.

Detailed explanation-2: -Whales are mammals and nurse their young just like cats and dogs. Instead of sucking the milk in, like other mammals, the mama whale pushes the milk out to the baby whale. Whales nurse their young from 1-3 years.

Detailed explanation-3: -The need for milk is an essential part of the development of any young mammal, and being aquatic makes breastfeeding considerably harder. Nursing their young with milk is one of the things that defines mammals, so whales definitely do have mammary glands and they do produce milk.

Detailed explanation-4: -Whales and dolphins, being marine mammals, exhibit the typical characteristics of mammals: they’re warm-blooded, breathe air, have fur (although only a few hairs or for a limited time period), give birth to live young, and produce milk to feed their offspring.
