It may be happy with the shell is has on. NEVER force a hermit crab out of its shell. but over time it will molt and change to a diffrent shell.
They probably come out of their shells to do it, but no crab has reproduced in captivity.
As hermit crabs grow and increase in size they need to come out of their shell in order to find a larger shell to live in.
To change into a new shell or to mate. If not for these reasons, it is very sick
Well, they live in shells, and when no one is there, they don't come out very often, so they are hermits. And they are related to crabs...so....hermit crabs!
Hermit crabs are scavengers. Litterally. They scavange for food and they scavange for houses. When they outgrow their old shell they look for a larger abandoned shell. Their shell is not grown by them. It used to belong to a shellfish.
Yes, they are nocturnal but also are active during the day, some of them dont come out as much as others, my hermies have not come out of their hiding place for months but there alive and well i check on them
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.
Do they grow there shell? Are they attached to it? Hermit crabs do not grow there own shell. They find discarded shells from other creatures like mollusks and move in to them. They hold on to the shell with their uropod at the end of their tail.This information was courtesy of http://www.thecrabbagepatch.com/faq.html
They just climb out. NEVER try to force them out! they would rather die then come out all exposed. Also it puts so much stress that they could die. If they want to change shells they will, but they are picky about them
yes they do becuse if they dont the part that goes in the shell is very tender and soft and can get dameged very easy so its good to have difernt sized empty shells in the cage so the crab can change the shells when needed
Hermit crabs are nocturnal, so it sounds like your hermit must have gone to sleep. Mine has slept for a week, once! If you get home and you find your hermit crab out of it's shell and looking see-through, then it has molted. Hermits usually molt on their 'birthday' but stay in their shells a while prior to molting.
It could be because the shell is dirty, to small or searching for a new one. Hermit crabs are always in their shells. Hermit crabs will never leave their shells unless switching. IF your hermit crab is running around without it's shell there is something wrong with it.AnswerThis could be because it has outgrown its shell and is searching for a larger one. A tight-fitting shell stunts the crab's growth, making it easier for a predator to eat it. There is always lots of competition between hermit crabs for their shells. This could also be because the hermit crab is stressed out because of lack of humidity or temp not being right. The hermit crab is vulnerable without his shell so separating him from the others and providing him with tons of shells helps. You can even use the cup method and place the crab gently in a cup with a shell. This helps sometimes.
