no they will drown
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%).
In oxygenated water hermit crabs can survive for a short time. Straws can stay under the longest as their modified gills most closely resemble marine hermit crab gills. However, the time varies between the species. Generally a hermit crab will only be under for a minute or two. As long as your pool has an easy way for crabs to get out they are good at regulating when they have been under too long. A hermit crab will not drown if he has a way to climb out.
Land Hermit Crabs consume fresh water. It is suggested by some pet stores to have two watering dishes. One for bottled fresh water and the other for bottled salt water. The hermit crab can choose between the two depending upon the nutrients it feels it needs. If you do not have salt water- that is fine, it is not necessary.
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.
yes hermit crabs can eat water flowers.
hermit crabs bathe in warm water
Land hermit crabs don't, they put them on damp sand at low tide, when the tide rises it carries the eggs away.
Marine hermit crabs live underwater and can sometimes be found in tidepools. Land hermit crabs do not live in the water but need fresh and salt water to survive.
No, nor the other way around. One breaths air, one breaths under water for their entire life.
