tamable

Remember that, unlike the zebra, they are tamable in captivity, you'll be soaring with me yet.

Some species of the rhinoceros, if not all, seem to be tamable.

Some of these baboons are as tamable and teachable as other monkeys, but they grow unruly and ferocious as they become old.

How is it, en passant, that some animals are naturally fearless and tamable, others not; and that even in the same family?
