Crustaceans

Crustaceans, like all arthropods, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.

They are invertibrates. Therefore they have an endoskeleton.

Yes, humans can eat krill. It is very rich in essential oils that the body needs, high in protein, low in fat (especially saturated fat), however does not have a very nice taste (although still considered a luxury in some countries). To overcome the bad taste companies have started to produce 'krill oil', which contains the oils from the krill that are good for the body, but have flavourings in to make it taste better.

Most crustaceans have four pairs of legs which means that they have 8 legs. They also have a pair of pincers which is at times counted with the legs making them 10.

It must be shed every so often to allow for growth.

It gets to be too heavy if the organism is very large; so it limits the size of the organism.

It regenerates. Because of the dangerous are's the crayfish lives in, God equipped the crayfish of the blessing of regenration. Whenever the crayfish loses a limb it can regenrate it. Of course it takes time to fully heal.

Giant isopods communicate by sending little water waves through the water.

Crayfish are not a single species nor do they belong to a single genus. They make up the superfamily Astacoidea, which contains three families and 29 extant genera.

The giant tiger prawn (Penaeus monodon) of southeast Asia is the biggest prawn, which can grow to a length of about 12 inches.

Scavengers prey on and consume those others creatures who have fallen and are unable to protect themselves. They help to break down and reduce the matter into smaller pieces. Scavengers can also be viewed as some of the Earth's cleansers, as they rid the land of the dead faster than decomposing does.

Crayfish shed their shells because they are growing. they do not shed their skin, but rather the inflexible shell on top. Because it is inflexible, it cannot grow with the crayfish and they have to make new ones. Replacing a shell is called "molting". crayfish and other crustaceans molt more when they are young and are growing faster. Hope this helps!

The body of a crustacean is composed of body segments, which are grouped into three regions: the cephalon or head, the thorax, and the pleon or abdomen. The head and thorax may be fused together to form a cephalothorax, which may be covered by a single large carapace.

they are found in the ocean where ever there are whales you can find krill

hell no! Tuna are at the top of the marine food chain... things that eat krill are like smaller fish or whales... tuna eat other types of fish.

The "shell" of the crayfish, or rather its exoskeleton, is composed of the polysaccharide chitin and some lipids. There are also some calcium salts in the exoskeleton of the crayfish, which gives it its firmness.

Exoskeleton: Crayfish have a hard shell, and no bones. That makes crayfish invertebrates (no spine).

Gills: Crayfish respire underwater through gills, where humans use lungs.

The circulatory system is the second one, the reason for this being that crayfish have no blood vessels (and humans obviously do).

You may be thinking of a crayfish, also known as a crawdad, crawdaddy, mud bug, etc. It looks like a little lobster.

Mainly through a small trumpet based on its left knee, other sources have claimed that they breathe through its antennae very much like a human using a snorkel. During large storms it is not uncommon to find large numbers of prawns that have choked to death on sea water.

Branchia, also known as Gills.

When they get too big for their present shell they go and find a bigger one, make sure you have some of various sizes available.

Don't throw them away they may be molting mine just molted. I thought he was dead but I kept him because he didn't fall out of his shell. He had white eyes. But I put him in the iso tank and he molted the next day, he was medium and it took three days. Be careful he is pink small and soft now and don't keep him with other crabs until he changes from his present shell they may eat him and don't throw his exo skeleton away he needs calcium.

Yes they do have bristles. They have three main places where they are at.In the Thorax the Abdomen And the Exopodite.
