Crustaceans

Crustaceans are the only arthropods with two pairs of antennae

Yes, the prawns are blended into a paste before being spread over the toast.

Yes, pill bugs are edible and taste much like prawns when cooked.

The anterior part of a crayfish is called the rostrum because it is a structure that protrudes from the head resembling a beak or snout, much like a rostrum on a ship. It helps the crayfish with sensory perception and sometimes functions in defense or capturing prey.

yes they can as long as you have enough space in there and it has enough water

The word means 'ten-legged.' There is an order called 'decapoda' which consists of the lobsters and crabs. The word is also used to describe a wheel arrangement in steam engines.

A blind shrimp is an arthropod often found in cave systems. They live in fresh water and get swept into the cave where there is no light. Over many generations, they lose their eyes because they don't need them. Hence, blind shrimp.

Crabs Breathing With gills as fish do, and they breathe on land by keeping their gills moist so oxygen in the air can still be absorbed.

Coconut crabs do not live in trees they live in borrows under trees. The reason they go up in the trees is to retrieve the coconuts up there. After the get the coconuts down they open them with their powerful claws and eat the coconut.

Yes

No. All species of crayfish which are not native to North America (European, Asian and Australian too) are susceptible to crayfish plague. The disease is caused by a water mould present in all America. Crustaceans die within few weeks of being infected.

What's more American crays are not only immune to the plague but also are carriers of the mould. This fact causes severe problems in Europe, where some American species were introduced (signal crayfish, swamp crayfish, belted crayfish) and now are increasing in number and range bringing European crays (bigger and of higher economical value) closer to the brink of extinction.

of course they defecate , and it smells gross some people EAT there defecate in places like Norfolk !!! When a person "de-veins" a prawn, they're actually removing the digestive tract, and essentially, the faeces.

They are scavengers, their planktonic larvae are a big food source.

Copepods are a subclass of crustaceans called Copepoda in the class Maxillopoda. There are several orders, each with several genera, each with several species. Just to provide one example out of many species, there is a freshwater copepod found only in the US called Aglaodiaptomus kingsburyae. See http://www.answers.com/topic/copepoda-2?cat=technology

It protects the crayfish from predators

The word's origin comes from middle English "lopster" which comes from old English "loppestre" which means, spidery creature.

A crab is a living thing in the sea .

yes a snail is a mollusk because a snial has a hard shell like all other mollkusks

Prawns go through three larval stages, the nauplius, zoea, and mysis. After this, they go through an intermediate phase called postlarvae, at which time they look pretty much like small adults and begin settling to the sea bottom.

The lobster-like alien character from Futurama is Dr John A Zoidberg, or simply "Zoidberg". Interestingly enough he comes from planet Decapod 10 - and lobsters are decapods (loosely, ten legged).

Humidity, temperature, substrate, shell conditions, etc.

There is no commercial krill fishing in the Southern Ocean that surrounds Antarctica.

Gravity

Prawns are invertebrates, as they don't have a spine.
