a Crayfish or crawfish. They overran the so-called Beast Barracks ( Bunkhouse 2-B) at Camp St. Joseph"s Villa in l968 along with other pests- which inspired the nickname, not wholly derived from the letters B.B. ( 2-B).

Most crustaceans start their life as an egg. They then become larvae and go through several stages before they become adults.

Sometimes fiddler crabs or other crab species are sold for aquariums. Most require brackish or even saltwater. Few thrive in freshwater. Most require live insects, worms, and/or small fish to eat. They can harass or kill other small animals in the tank with them. Many have nasty pinchers. For this reason, they are best suited to a set-up solely for them. Almost all of the crabs sold for "freshwater" tanks require a haul-out spot. The water level must be low enough to allow them to get in and out of the water with ease. If denied the ability to get out of the water, they will eventually die. They most likely also require full spectrum lighting over the basking site but studies probably have not been done on this. Fiddler crabs and similar species stay relatively small, at a few inches in size.

Because its hot in there and the dark retrc=acts heat so thats y im so awesome

Yes, it is in the Phylum Mollusca, which also include...octopuses, squids, clams, and mussels

Ctenophora do not have specific organs for breathing. They use their entire body's surface for gas exchange through simple diffusion

Sharks eat each other quite often. Sharks can also be eaten by any larger fish - if the shark is young or quite small, a barracuda or grouper could eat it.

The females hold the eggs with the swimmerets. They can also be used to swim.

A ghost crab isn't a single type of crab, but is a group or related crabs of the species Ocypode. They have a bit of range in their sizes, as you might guess, but the largest ones run just a few ounces, tops. A link is provided below.

the cray fish send to the factory alive because when they send it they put it into ice and when we want to eat it will be so fresh!

to hold their eggs

pooing in ur shooz, lyk reli big 1s, den u put ur fut in nd its like er i gt poo on mi new white socks. OH NO IM GUNNA HAVE A WOODLOUSE BBY!

female birds eat them for calcium to make their eggs healthier

they live in the trench layer. [deepest part of the ocean.] they live next to hydrothermal vents in the ocean. they eat bacteria and mussels that grow on them.

Crustaceans have exoskeletons, two pairs of antennae, two pairs of maxillae, biramous legs, and mandibles, which are like jaws.

Because they are underwater. They have to get oxygen that is dissolved in the water instead of that available in the air. Fish have an air bladder which controls their buoyancy. Some fish can use it as a lung. When they swim in the water they use their gills. When they are on land, they use their lung.

yes,it consumes some of the roots of the plant rendering them useless, they also eat small leaves well flowers uuum im not sure about that.

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.

The common crayfish (crawfish) lives about 2 or 3 years, but individuals may live to be as old as 8 years. Some rare species can live as long as 20 years.

After reaching 2 years of age, they have usually grown fairly large and have difficulty creating larger shells beyond a certain size. Each new molting makes them more vulnerable to predators.

Yes. I know because they wear rainboots.

To feed, crustaceans take water over their "filters," and then use appendages that "filter" food out of the water.
