Genesis 1:21

And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind. And God saw that it was good. Not only the fishes were made by God to inhabit the seas, but He also created long and huge whales, crocodiles, and other monsters of the oceans and rivers, and every form of marine animal, no matter of what form and nature, with which the waters swarm, and every kind of winged animal, chiefly birds, all of them perfect and exactly adapted to the element in which they found themselves.
