Shrimp tail is the tail of the crayfish, the head of the crayfish removed, the rest is the tail of the shrimp. Shrimp tail and crayfish are practically the same, shrimp tail is the crayfish to remove the head, so there is no difference between the two. However, when buying, generally speaking, shrimp tail is more expensive than crayfish.

Because most of the toxins of the crayfish are gathered in its head, so generally do not consume the head of the shrimp, eating is easy to jeopardize health. Crawfish is best to eat only the tail of the shrimp.

Frozen shrimp tails are not as tasty to eat as fresh crayfish, and the nutritional value is not as good as fresh shrimp. So when buying shrimp, it is best to be able to pick fresh crawfish.

Crayfish will be corrupted and decomposed after death, easy to breed bacteria such as Clostridium botulinum, so it is recommended that you do not buy shrimp tails, directly buy live crayfish safer.
