All forms of crustaceans (crabs) have pincers to catch their prey/food. They clamp their pincers around the victim to stop them from getting away before they begin eating them. Sounds gruesome doesn't it? LOL. But seriously, that's what they use their pincers for, no kidding.

They are different because crayfish have pincers but birds do not.

Crayfish have developed eyes on short stems that help them see their environment. They have adapted to blend in with their surroundings and have pincers to help them defend themselves.
A crayfish doesn't really have to use too much conniving to capture its prey, as it will just eat anything that doesn't get out of the way fast enough. The crayfish will grab food with its pincers and eat the food.
The chelipeds, mandibles, mazillae, and mazillipeds
A crayfish has a pair of mandibles and several pairs of maxillipeds in its mouth that help it to crush food. The mandibles are like small pincers, while the maxillipeds are used to handle and manipulate food before it is eaten.
the crayfisherman brings the crayfish alive in the factory and puts them in ice or cold water that's what keeps them alive
