The brevity of the words belie the explosion of the sea's diversity and remarkable potential for adaptation: "Then God said, 'Let the waters abound with an abundance of living creatures'…So God created great sea creatures and every living thing that moves, with which the waters abounded, according to their kind…And God saw that it was good. And God blessed them, saying, 'Be fruitful and multiply, and fill the waters in the seas…' So the evening and the morning were the fifth day" (Gen 1:20-23). God saw it all and pronounced it good, but we humans are just beginning to catch up.
