Yes they can as they are like many other crustaceans have tendency to live on both land and in water
no they'll drown
It should be at a boiling point when cooking Crabs; as Crabs and Lobsters don't like very - hot bioling water.
There are crabs which breathe water and crabs which breathe air. It is rare to find a crab that does both but intertidal crabs do but they must remain wet to breath air (strange, right?).
Land hermit crabs can't breath out of water, they will drown, they have modified gills, which means they need humidity to survive. (70-85%).
Some crustaceans are adapted to be able to live on land and breath oxygen from air and water. The ones that live when they are taken out of the water are land crabs, which will usually only return to the water to breed. When crabbing, the containers hold water so that crabs who only live in water are able to survive and be sold as fresh crabs.
Yes
Yes, there are many types of crabs that live in fresh water.
Because even though crabs are water animals unlike most water animals they can breath on land.AMAZING!!!!
no. hermet crabs neeed water to live therefore it will not survive in a hamster cage.
No crabs cannot live in a tropical tank. If you go to a petstore they will try to sell you small fiddler crabs, however they do not live in freshwater, they live in brackish water like most small crabs. All brackish water crabs need to be able to be out of water for a certain period of time. If you do buy one of these crabs and put them in your tank they will only be able to survive around a month.
As most people know hermit crabs have gills most animals that breathe under water have gills for example a fish. The hermit crabs gill's can work on land but in order for the hermit crab to survive they hermit crabs gills have to be moist....
Hermit crabs can live for some time without water however it is not recommended and the more time that they are without water the more suceptible they are to disease and death. i have seen crabs live for over a month without water but most do not survive long after that, even when the are moved to ideal surroundings.
