Crustaceans

i am not positive but i think it is calcium because i know they need liquid calcium drops if you have one as a pet.

I live in New Rochelle, New York and I have recently seen many crayfish migrating away from Glenwood Lake and being killed by the dozens on an adjacent road. Why is this and where are they trying to go?

insect

where their blood circulates through an open-circulatory system

nephridia

A statocyst at the base of each antennule enables the crayfish to keep its balance.

Yes

Lean meat is a good food for them as are earthworms. They also like cheese. You could possibly get some crayfish food at a pet shop too.

Yes

You can't, because they illegal to import. There is a native species- if you live in the south island, you might be able to collect some yourself.

I live in nz and i have 4 of them in a tank

Melted butter with lemon; anything else would be sacrilege.

I believe they all belong the order Sharkcus Taffius. Thank you.

The class Crustacea comprises the majority of the marine species of the arthropods, although there are many freshwater species and even a few terrestrial ones such as the common sowbug. The most familiar are shrimps, crabs, and lobsters, but the diversity of the crustaceans in form and biology ranges from the gigantic king crab of the Pacific Ocean to a myriad of planktonic forms comprising the dominant herbivores of the ocean.

Yes, Annelids have bilateral symmetry.

Because they have 2 eyes, they are usually listed as bilaterally symmetrical.

The word scudded means to move quickly.

Example: During the strom the clouds scudded in the sky

Red fish work best for crayfish. But anything will do really. Kahawai, Gounard etc.

a crustacean

Climb out of Tank -- I have a red claw crayfish ( cherax destructor ) and it climbs a lot, also likes to make holes and attack my fish. Do not keep slow moving or long fined fish in the same tank, as the crayfish will attack it and soon eat it.

They are primarily bottom dwellers and feeders. There are hundreds of species that live in all different marine environments - freshwater, salt, brackish, creeks, rivers, and ponds. Further north, the only additional requirement is that the water be deep enough that they can survive beneath the ice sheet. The hide from predators and are most commonly found near rocks, grasses, or mud in the water. Some species burrow or tunnel into the muddy banks and beds, even leaving the water to bury themselves at the edge to further protect themselves, particularly pregnant females.

Among crustaceans rather than humans): Horns.

There are many species of daphnia and they are found across the globe. Daphnia is most used in fish culture due to their cost and availability. The scientific name for the Daphnia is"Cladocera." They have many legs and are a brownish color. The reason why you can identify the colors is because of the fact that daphnia are actually transparent. The majority of Daphnia are filter feeders which means that they help clean up the ecosystem by feeding on algae or bacteria which is sometimes very dangerous to humans. This makes them extremely popular in large lakes. In fact, it is possible that about 100,000 of these "water fleas" occupy every cubic meter in the Great Lakes. Even though these crustaceans may seem out the ordinary, they are like many other animals in the ecosystem, with legs, antennae, eyes and even a nervous system, making them perfect for scientific studies, such as toxicity studies due to the fact that they feed from the same water they live in.
