Although I do not recommend keeping hermit crabs from the ocean, yes you need saltwater. They are salt water creatures.
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....
You Can but there's a water shack in hermit crab the keep the moister-ed and by washing them can destroy it
Hermit crabs carry water in their shells to keep their abdomens moist. When they get picked up and tilted, the water can come out. It's harmless and they can easily replenish it if they have access to fresh and salt water in their enclosure.
No, it is not legal. You must have a permit to harvest hermit crabs from the beach even if it is only one. Additionally, the majority of the hermit crabs found on the beach especially in North America are marine hermit crabs and they will not be able to survive in the kind of habitat that is designed for Land Hermit Crabs. They need a full salt water reef setup and must live under water.
The kind of hermit crabs most people think of are Land Hermit Crabs. They live on land, and need at least enough water to submerge themselves. Land Hermit Crabs do need sea salt to keep their body chemistry balanced, and as such, need access to both salt and fresh water. Marine Hermit Crabs require a full saltwater aquarium to survive. Such tanks are elaborate, and should be researched thoroughly before purchase. Saltwater pets of all sorts are often regarded as difficult to care for.
The only reason why a person would hunt a hermit crab would be to keep it! There are some cultures that eat hermit crabs.
not pet hermit crabs... they are too weak and fragile to keep the hermit crab save although wild hermit crabs might use them the would be sea snails which have harder shells

well as long it isn't that deep or else they will drown so keep an eye on them
Yes. The best way to deliver them water is a soaked sponge in a small dish. Be sure to keep it moist.
A hermit crab needs food, water, a spray bottle to spray the ground, and a shelter their might be other things but that is all i know.
i your talking aboute water hermit crabs then they usually go arround looking for food or walking to find a spot to keep them underwater during low tide,if you meen land then they would go out and look for food too or walking to find a warm spot because hermit crabs are ususly found on places near the equater.
