Are Shrimp, Lobster, Crayfish and Crab Halal?
Yes, those are halaal:
Hence all kinds of food from the sea are permissible, whether they are plants or animals, alive or dead. Allaah says (interpretation of the meaning): “Lawful to you is (the pursuit of) water-game and its use for food – for the benefit of yourselves and those who travel…” [al-Maa’idah 5:96]. Ibn ‘Abbaas said: “ Sayduhu (lit. hunting, pursuit) refers to whatever is taken from it alive, and ta’aamuhu (lit. its food) means whatever is taken dead.”
Full fatwa here which explains in more detail, which also explains if animals such as Crocodiles, Frogs, Otters and turtles are halaal or not, but to summaries the fatwa:
Crocodiles = Haraam Frogs = Haraam Sea Snakes = Halaal Otters and turtles = Halaal but only after slaughtering them in the islamic manner Any food which can cause you harm, even if it is from the sea is Haraam.
