Great answer dear brother!
Can a rat be TAYYAB? No way!
Wherever in the Qur'an we find instructions about eatables we find two conditions: Halal & Tayyab.
Tayyab = Decent = Aesthetically sound = Neat and clean.
I think, the brightest Azizam Jawaid got confused between two separate injunctions of the Qur'an.
1 - BAHEEMA-TU-AN'AM = Herbivorous live stock = Cattle = Camel = Sheep = Goat = ?Herbivorous animals of land etc.
I had said that the dog could not be Halal since it is a carnivore. But he raised the question about Shark fish which is a carnivore.
But there is a second rule.
Let the Captain & Azizam say a few words about birds.
2 - Water-game: I see no contradiction in all water game being Halal with Number - 1.
