Crustaceans

the group of a krill is called an effusion of krill

yes. because a symmetry is when you draw a reflection so radial reflection is just if you draw the reflection but in the colors it has drawn.

Many humans eat crab and stuff like that at restaurants.
Mostly birds that live near water however many types of fish such as the striped bass like crustaceans in their diet as well

10 total. There are 4 pairs of walking legs and 1 pair of chelipeds (these are used by the male to transmit sperm to the female and used by both genders to bring food closer to their chelicerae/mouthparts)

We recently studied arthopods in zoology.

Crustaceans move by at least five pairs of jointed legs with one pair of jointed legs per segment.

Triops can eat a range of fish food (pellets not flakes).

Triops can also eat:

grated carrot

rice

small pieces of fish

prawn(not much bigger than food pellets)

ranges of fruit

I got all this information and more at www.triops.bravehost.com

Nope, roly polies are herbivorous, feeding on rotting leaves and such. ^^

What are you compairiing them to? They can be homologous to one thing, but alanogous to another. Please find the definitions of your possiblities before asking people for answers to your homework.

Crayfish have the ability to regenerate practically any appendage that gets broken off. They can regrow legs, claws,antennae, even eyes if they happen to get snipped off in a fight.

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.
