Leviticus 11:11 BBE

⁹  These you may have for food of all things living in the water: anything living in the water, in the seas or rivers, which has special parts for swimming and skin formed of thin plates, may be used for food.

¹⁰  All other things living and moving in the water, in the sea or in the rivers, are a disgusting thing to you;

¹¹  They may not be used for food, and their dead bodies are disgusting to you.

¹²  Anything in the water which has no special parts for swimming and no thin plates on its skin is disgusting to you.

¹³  And among birds these are to be disgusting to you, and not to be used for food: the eagle and the gier-eagle and the ospray;
