Leviticus 11:9-12 - Clean And Unclean Aquatic Animals
9 These shall ye eat, of all that are in the waters: whatever hath fins and scales in the waters, in the seas, and in the rivers, them shall ye eat. 10 And all that have not fins nor scales in the seas, and in the rivers, of all that move in the waters, and of any living animal which is in the waters, they shall be an abomination to you: 11 They shall be even an abomination to you; ye shall not eat of their flesh, but ye shall have their carcasses in abomination. 12 Whatever hath no fins nor scales in the waters, that shall be an abomination to you.
