Crustaceans

This is way to vague and confusing. Please rephrase and resubmit. Be more specific.

it is the antenna, antennule, rostrum, and the maxillipeds (feeding appendages).

Yes, crayfish are freshwater crustaceans. They resemble small lobsters, which they are closely related to. They are mostly found in brooks or streams with running water and with shelter from predators.

one way to determine the gender of a crayfish is to look at the first 2 pairs of swimmerets. The males are longer and prong shaped

about 5in.

Generally the first two swimmerets of the male crayfish are significantly larger than the rest. The swimmerets of the females are usually all the same size.

Crabs are not arachnids, they are decapods. Decapod means '10 legs', it is just that crabs and some other species have specialised pincers on the front pair, meaning they only walk on 8. However the pincers are technically legs.

Sea gulls and Pelicans prey upon saltwater crabs.

There are several species of crayfish in Australia, including the red claw crayfish, Cherax quadricarinatus and the yabbie, C. destructor. The world's largest crayfish, which can grow to almost 7 pounds, is Astacopsis gouldi, found in Tasmania.

they both have hard shells and are highly equipped with protiens.

Xanthid crabs eat mostly on algae, but also eat other marine vegetation. Xanthid crabs are poisonous and cannot be eaten by humans..

the end of the crayfish by the telson the tail is the flipper.

If its in a pond probably, but if its in a small enclosed area, then the crayfish can eat the tadpoles.

im not sure about bread but when me and my dad go crabbing we use chicken legs and pretzels crabs really like the salt and if u go crabbing you go where fresh water and salt water meet it is usually rocky and marshy

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.
