How are the antennae chelipeds other walking legs and swimmerets related?
Antennae are sensory appendages that detect chemicals and vibrations, chelipeds are specialized for grasping and defense, walking legs are for mobility on land, and swimmerets are used for swimming and reproduction. Together, they all play important roles in the overall functioning and survival of the crustacean.
How are antennae chelipeds other walking legs and swimmerets related?
The chelipeds aren't really related to the movement of the crayfish itself, unconciously these appendages might move the crayfish, but really the chelipeds are a form of defense and used for food handling, much like the one big claw of the "Fiddler" Crab.

How many appendage does a crayfish have?
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.

Where on a crayfish's body are eggs stored?
The eggs are attached to the underside of the abdomen (on the outside of the body). Then the eggs hatch there. After the eggs hatch, the baby crayfish stay on the same part of the mother's body, for about 2 weeks. The babies are very small when the hatch.
