A crayfish's mouth is located on the bottom side of its head, just behind its antennae. The crayfish has numerous mouth appendages including 2 sets of maxilla, 3 sets of maxillipeds, and mandibles.
I think from disecting a crayfish in my Biology class, that crayfish have 5 sets of different appendages. All in all, the crayfish we disected had 36 actual appendages. Appendages are areas on an animal that "stick out". Kind of like our arms and legs except crustaceans and other animals have more, and can grow them back if they are cut off. Like I said, total, our crayfish had 36 appendages from anterior to posterior. There are a total of 38 appendages, 19 on each side.
No. They breathe with gills. But they can walk around in the air for a short time because they can hold onto a little water in their gill area.

One Gill is 1/4 pint.

Crayfish can sense changes in water pressure. They can also see to a limited extent. Additionally, they have two sets (pairs) of antennae that are sense organs. A link can be found below.
Many people think there is no predators of crayfish in England. Well they are morons who don't see many river animals. My mum LOVES crayfish and me and my family are from England and in fact, we caught 4 crayfish today and we got them in a pot. There is actually natural predators. Herons, otters, wild, feral or stray cats, mink and other crayfish eats crayfish.
