Crustaceans

They can stay up anytime but they are rare to find at night.

The fiddler crab has stalked eyes because it helps to see around it more. The eyes are above the crab instead of being just in front of it, so if a predator comes around, it might have more of a chance of getting away

The primary excretory product of crayfish is that of a small amount of ink. Due to evolution present day crayfish no longer possess a large ink bladder. This is due to the shallow water they reside in and the extra weight the bladder would have put on the animal.

prawn live in both salt and fresh water whereas lobster live in salt water. lobster has claws and hard shell and prawn don't have claws and hard shell. prawn are small in size compare to lobster.

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.

I am not sure, but from what I can conclude from diagrams and from a recent dissection no, the crayfish does not have a liver. Although you should consider asking your biology teacher just to be sure.

Not at all. Shrimp and prawns are a good source of lean protein. They would fit into almost any diet that you are on. They could made to be unhealthy if they are covered in a sauce that is loaded with fat or sugar. Eat them plain or with cocktail sauce or tomato sauce... If you want sauté them use a small amount of olive oil.

When they grow, they have to molt their exoskeletons. That is also less accurately described as "shedding their skin".

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.

They don't eat chicken, they're crayfish.

No they don't

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"

Yes or no can not answer this question because the size depends on the type of crab.

it is a monkey sex position...related to 69...it is preformed when the monkey is on vacation with his shrimp friend, dick and his girlfriend, mrs.crabs....it happens on the beach

Crayfish and Lobsters belong to Class Malacostraca.

The function of a goldfish's tail is to move it around.

The rostrum on a crayfish is a hard beak extending from the head that is used for protection.

The lifespan in captivity is about 13 years. In the wild it is an average of 11 years.

The outer covering of a crayfish is it's protection. You may notice that the shell is very hard. This protects it from preditors, that is the reason it hides, to keep itself hidden from pretitores who might attack.

Crayfish are not poisonous, though some may get you with their big claws. But it only feels like a pinch.

These filter out waste materials in the crayfish. They perform basically the same function as our kidneys.

Crayfish are crustacean which has a hard shell so htey are invertibrates. (No Back Bone or Spine.)

Crayfish have one pair (i.e., two) compound eyes, located on eyestalks at the front of their head on either side of the rostrum - the "nose" spike. Each compound eye is made up of thousands of tiny lenses arranged in a convex grid.

actually crawfish are crestations. they are kind of like amphibians they live partly on water and partly on land. craw fish enjoy damp areas but they also need a dry area.

so just subduing a crawfish in just water will kill it. therefore the above answer is incorrect and you are not stupid. =) (=

anywhere in the water sometimes a creek i live near a creek and checked under rocks and saw a crawfish... so i got and made a trap put it set it and checked the next day

The crayfish could be a primary consumer but it matters where it stands in that particular food web.
