Yes. Mammals do use their mammary glands to nourish their young, which is located in the groin of the whale.
Sarks are fish, not mammals. They do not make milk or feed their young with milk.
yes
Yes...
Yes
Yes. Both platypuses and echidnas, which are the only egg-laying mammals (monotremes) nourish their young with mothers' milk. This is the defining characteristic of a mammal.
Yes whales do have belly-buttons. Whales are mammals and to be classified as such they need to fulfill certain criteria. They breathe air, have hair, give birth to live young and nourish their young with milk. When a whale is born it is still attached to the cow (mother) by the umbilical cord which then needs to be detached (exactly how this is done is not fully known). leaving behind a belly button or scientifically the 'umbilicus'.

They drink milk from their mother, i think.
Yes, as mammals whales nurse their young. It is no surprise that whale milk is much different than what we normally associate as being milk. Being that whales are in an aquatic environment, their milk is suited for where they live. It is much, much thicker than other milk. I have heard it described as being much more like sour cream in thickness and in fat content. This question goes to show how unique mother's milk is no matter what species the mother is and how precisely it is designed for the baby who drinks it.
