Do crayfish have a nervous system?
Unlike humans who have a big brain and lots of nerves to send signals down the body, the hermit crab and other crustaceans have a much more primitive system. They have a primitive ventral nerve cord and ganglia system similar to an earthworm. Hermit Crabs have good vision thanks to their compound eyes on stalks (although can't look below them) and sensory organs are found on the body. Like true crabs, hermit crabs have bristles and hairs all over their body - but mostly on their walking legs - which act as touch receptors. The long antennae of hermit crabs - longer than other crabs - have smell sensors, used to find their food. Smell detectors are also found on the legs. When a hermit crab walks over food, its legs smell it, and the chelipeds quickly grasp it and move it into the mouth.

Quote from similar question "Crayfish are omnivorous and will eat a wide variety of foods, including plants, insects, frog eggs, small fish, dead plants and animals and worms. They commonly feed on submerged, decaying vegetation, deriving nutrients mainly from the bacteria and other decomposers associated with it"
Where do crayfish lay there eggs?
Crabs lay eggs in the shallow waters. It is difficult to see them when they do, because crabs need to molt their shells to breed and so tend to go into hiding until their new shells harden. Also crabs usually carry their eggs around for only a short period before casting them adrift into the currents where they hatch and the "baby crabs" live amongst the plankton for a while. During this time they look more like barely visible prawns. The tides eventually bring them back to shore, where they will molt their shells and change into "proper" baby crabs to spend the rest of their lives amongst the rocks and seaweed.

How many legs and claws does a crawfish?
walking legs on a crayfish are used for mobility and movement, while the claws remain free to forage for food. This allows the crayfish to eat on the move and travel fair distances in a short time.
How many pounds of crawfish will feed 10 people?
Depends how much of a porker each guest is. For the family at home, I usually figure a 4 to 5 oz. portion of meat per person. Fish portion would be a smaller size portion, due to cost, and chicken would be larger. It depends on your budget and personal weight. For guests, I would offer a 5 to 6 oz. portion. Don't forget that the meat is not the only thing being eaten, like salad, veg., rice or potato, and later dessert/fruit. So if I was making pulled pork for 10 people, I would most likely buy a 5-6 lb. roast (trimmed), figuring generous portions and that I might be lucky enough to have leftovers if I make a big batch of Caribbean Peas and Rice to go with it.
What are pincers on crayfish for?
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.
When is crawfish season in Arkansas?
Crawfish "season" typically runs from March through about June. This is when you will get your best crawfish. From August to February the shells on the crawfish are quite hard and not as easy to peel, and they are not as "fat".
And, there is actually a season. Crawfish harvesting begins in the Spring, thus this is why your best crawfish are in the early spring months.
Crawfish farms consist of ponds that are drained and replanted in the summer, reflooded in the fall and winter, and begin harvesting in the spring. Laura

A crawdad's gills are located on the underside of its body, attached to its legs. They are feathery in appearance, giving a large surface area for allowing its blood to release carbon dioxide and absorb oxygen from water.
The top side of a crawdad, above the gills and legs, is called the carapace, which is the shell on its back.
