Which animal's young is called a calf?

The previous answer stated "Cow." But, there are much more, such as: Antelope, Bison/Buffalo, Camel, Elk, Moose, Elephant, Giraffe, Hippopotamus, Porpoise, Reindeer, Rhinoceros, Whale and Yak.

All of the ones listed above are called "Calfs" (or spelled "Calves") as babies.
