Then God said, "Let the waters swarm with fish & other life. Let the skies be filled with birds of every kind." So God created great sea creatures & every living thing that scurries & swarms in the water, & every sort of bird - each producing offspring of the same kind. And God saw that it was good. Then God blessed them, saying, "Be fruitful & multiply. Let the fish fill the seas, & let the birds multiply on the earth." Genesis 1:20-22
