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.
crayfish live in water but not to much or they will noy survive

Creatures do not make their habitat though often modify it.
not very well because they need a flowing river to eat stuff from... that's my theory
They need to have food (they prefer fish and crayfish, but eat what is available), water, and a good large habitat. river otters often die from pollution and/or loss of habitat.
I think trout, fresh water shrimp, fresh water crayfish, caddisfly lava live in fresh water.
That would be the Tasmanian Giant Crayfish, Astacopsis gouldi, which gets to be about 15 pounds, making it also the world's largest freshwater invertebrate. Found only in northern Tasmania, it is now highly threatened by habitat loss.
Crayfish
Raccoons obtain their drinking water and much of their food from ponds, including fish, frogs, crayfish, snails, snakes. etc.
In the wild, you will find crayfish eating dead fish or shrimp as well as plant material. So if you are going to have them in captivity, it is best to feed them plants such as lettuce and of course you can use crayfish food. This consists of things like pellets of shrimp or even algae. They need places to hide, luek warm water, sand, rocks, shells, water, and food.
My older crayfish died and my littler crayfish has not yet how do/can they die?
Crayfish are known as both crayfish and yabbies in Australia. "Yabbies" are freshwater crayfish, often found in rivers, creeks and dams in rural areas.
