Are whales mammals? How to breastfeed?

Whales are mammals. Whales breastfeed by feeding.

Whales are mammals that live in water and have the same physiological characteristics as terrestrial mammals. Because there are no flexible limbs to grasp and no flexible lips, the calf can only wrap its mother's nipple with its tongue to feed. At the same time, the mother whale will keep her body relatively still, and sometimes she will turn her belly over to help the young whale feed.

Nevertheless, the young whales eat for a short time at a time, only a few seconds. In order to improve the feeding efficiency, the mother whale injects milk into the calf's mouth. In just a few seconds, the injected milk can reach 10 liter.
