Is the cray fish a fish?

No, crayfish are not fish. They are crustaceans, which are a group of arthropods that also includes crabs, lobsters, and shrimp.

Here's why:

* Different Anatomy: Crayfish have a hard exoskeleton, segmented bodies, and ten legs, unlike fish which have scales, fins, and gills.

* Different Breathing: Crayfish breathe using gills, but these are located under their exoskeleton, not in their mouths like fish.

* Different Reproduction: Crayfish lay eggs, while fish typically lay eggs or give birth to live young.

* Different Habitat: Crayfish live primarily in freshwater environments, while fish can live in both freshwater and saltwater.

So, even though they are called "crayfish", they are not actually fish.
