Well yes they do, beceause the back part of them is very soft. Give it a shell it likes. They are very picky about shells. my hermit crab went through 3 shells befor it found the right one.
so when the eggs hatch the baby hermit crabs know where to get the water so they can have it in their shells to breathe.
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.
Sometimes it is because they outgrow the old one. They spend most of their lives looking for the perfect shell!
Hermit crabs don't require lots of care but do need some. Like, Water, Food, Water dish, food dish, extra shells, things to climb on, hermie hut (or place to hide,) correct substrate, and hermit crabs.
hermit crabs need a beach to lay their eggs on so they wont have babies in their cage.
Hermit crabs change shells once and a while so put about maybe 3 or 2 per hermit crab.I have my own hermit crab and i thought this question.But my hermit crabs havent been changing shells a lot.And make sure you use the right size because hermit crabs dont change shells if that shell is to small or to big or have holes in it.Have Fun With Your Hermit crab
hermit crabs need to live in 70-80 degree temprature
Yes! It is very important that a hermit crab has a shell, it is used to protect their bodies. It also saves them from getting eaten by other animals! Though sometimes, you find hermit crabs that haven't found a shell that isn't the right size or shape, and instead of a shell, they might carry things like bottle tops. Usually, hermit crabs try to avoid situations like this but, when they urgently need to change into another shell because their current shell is too small, it will be unavoidable.
I'm not so sure if they need a companion, but they certainly enjoy company. If you are getting pet hermit crabs it would be advisable to get three or four, and as hermit crabs aren't too expensive, you should think about it.
They have a shell because their abdomen is very vulnerable and they need a shell so that the abdomen is protected from predators
They change their shell if they see a better looking one, and if the outgrow their old one.
yes if there shell gets to small they will go to other shell! P's I'm 8
