A crayfish can have as many eggs as it wants it just has to be healthy but I think it can lay 50-200.
Crayfish can hear, but they do not have ears, so they do not hear in the usual sense. Our ears pick up vibrations via the eardrum and tiny bones in our ears, but crayfish have thousands of sensory bristles. Some of these sensory bristles respond to chemicals, others to touch, but either way, they enable te crayfish to not only hear, but also to smell and feel.
No, they do not have ears. But they can detect sound; the hollow hairs on the outside of their bodies pick up vibratons caused by sounds and vibrations in the water. These hairs are also used for feeling, tasting and smelling.
