Why would a hermit crab have a white bump on its shell?

Answer: The shell would have had to have it before the hermit crab moved in or something got stuck to it.


How do hermit crabs make a new shell?

The shell that the hermit crab adopts and wears and changes many times throughout his decades long lifetime helps him in several ways. The hermit crab has a very delicate abdomen that is protected by the shell. Without this shell, his abdomen could become punctured very easily and the crab would die. The hermit crab also carries water in his shell to keep the abdomen moist. If it were to dry out, again, the hermit crab would die. The crab balances the salinity of the water within his shell by accessing fresh or salt water as needed. The shell is also his shelter, and protects him from predators. The ideal fitting shell will allow the hermit crab to pull fully inside and to block off the opening with his large pincer.


Your hermit crab fell off the counter and broke some of his shell what do you do?

Try to get another shell that you have that is simmilar to the original one. Then I would pit the hermit crab in a small tank with the new shell ans see that he gets into it.


Can you pull a hermit crab out of the shell?

yes but why would you want to do such a cruel thing


Can hermit crabs live in the ocean?

Yes it can but it depends what kind of shell. The shell must be like a conch shell, but not the kind for snails. There would be not enough room for the crab to squeeze his body in. You need a shell with an opening a little bit bigger than the shell opening it already has on if you want it to change into the new shell. But most the time they do not change shells (I have had one for over a year and it still hasn't). I know you probably want it to change into the pretty new shell you bought or found but do not try to manually do it for the crab.

Can you put hamsters in a tank with hermit crabs?

Don't do that! Hermit crabs may get out of their shell to change into a new shell or even get out to eat some lettuce or drink water from a water absorbed sponge. During that process who knows what the hamsters would do to the hermit crab. They're not meant to be in the same cage!


Do hermit crabs have tongue?

Why do hermit crab change shell?

They change shells because the hermit crabs will grow like us humans. Just imagine that if you were a human and had a shell, you would want to change right?? They like alot of differetnt colors and styles. They outgrow their own shells and need new ones once and awhile. :) I own three myself. I hop my info helped alittle :D If you need anything else write it on here:))

Can you touch a hermit crab after it just changed its shell?

It depends how long it has been from when he changed its shell. if it has been less than a day I wouldn't just in case but after a day it would be safe to.


What would happen if the snail shell wasn't there for the hermit crab?

The hermit crab would be endangered, and use other things to protect its abdomen, such as bottles, washed up shells, and other things they could find. So they would be more open to predators.
