Ou, em Inglês:
«According to Leviticus 11:9–10, anything that comes from the water ("in the seas, and in the rivers") that has both fins and scales may be eaten. By those requirements, kosher water creatures can only possibly be fish, but even then, permitted are only those fish that have both fins and scales.
All other non-fish water creatures are, by default, also not kosher, including amphibians, crustaceans, molluscs, water-bound mammals, water-bound reptiles, etc.»

«9 These shall ye eat of all that are in the waters: whatsoever 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 and scales in the seas, and in the rivers, of all that move in the waters, and of any living thing which is in the waters, they shall be an abomination unto you:
11 They shall be even an abomination unto you; ye shall not eat of their flesh, but ye shall have their carcases in abomination.
12 Whatsoever hath no fins nor scales in the waters, that shall be an abomination unto you.»
