This question makes no sense.If you are asking why YOUR hermit crab is all beat up, the chances are that another crab got to him while he was molting and still soft, and caused him some serious damage.
http://www.hermitcrabparadise.com is a great place to go and ask this question and give more detail about what you think might have happened.
Yes your crab is molting she took the water down with her so she can keep hydrated while underground for awhile.
the hermit crab ecosystem is really interesying!you see,all they do is molt! the hermit crab ecosystem is really interesying!you see,all they do is molt! the hermit crab ecosystem is really interesying!you see,all they do is molt!
not all hermit crabs bury themselves so nothing is wrong with your hermit crab
a hermit crab can go all the way out of its shell to switch shells
It all depends on the size of the hermit crab.
the crab will sooner or later die off DO NOT REMOVE THE HERMIT CRAB SHELL if a crab dies out of it dries out and its a slow death so for the sake of the crab DO NOT REMOVE THE CRAB SHELL
possibly, but most likely no. the outside should crumble/break/crack, allowing it to come out. Another view: Your pet hermit crab should molt under the substrate (sand, or Eco Earth, NOT calci sand, which hardens like a rock when it gets wet and dries, never use as a substrate. put in their food dish instead). There are occasions when the hermit crab will surface molt, but this is not normal. Most often there is not appropriate substrate available (as in having only gravel, which is NOT hermit crab friendly, they need sand) or the crab is unduly stressed. There are some videos of hermit crabs surface molting on YouTube, if you are curious, do a search and watch those. A hermit crab should never be disturbed when it is molting, never ever dig up a burrowed hermit crab. Molting can take a couple of weeks up to several months. Just keep the tank temperature and humidity in proper hermit crab ranges, change out the food and water dishes regularly, and leave them alone. They need darkness to trigger the molting hormone. Molting is their most fragile time, and they can easily die if stressed or disturbed too much during molting.

Yes, it will grow back.The body you see is actually a shell that the hermit crab sheds to grow. you can get all your hermit crab info on HERMIT-CRABS.com
Yes they do, my hermit crab Junior sleeps all day!
It depends on the size of your hermit crab. They can take as little as one week, up to several months. The average time for a smaller crab is 3-4 weeks, but can take much longer, so don't be tempted to dig them up if they are under for a very long time. While molting under the surface, your crab is shedding his old exoskeleton. His new exoskeleton needs some time to harden, and then he will eat his old exoskeleton. He needs this as it helps him replenish the calcium and protein to help his new exoskeleton harden and to give him energy. He may surface before his new exo is fully hardened. He may appear pale, and lethargic. Do not disturb him at this time. Wait until he is acting normal, with normal energy and color, before you pick him up and play with him. He needs time to recover without being disturbed. Make sure you provide him with plenty of protein and calcium and chitin sources after he surfaces, such as shrimp with the tail still on, dried mealworms, freeze dried shrimp (without preservatives, ethoxyquin and copper sulfate are toxic to hermit crabs). Give him a little honey or coconut (unsweetened) in his dish for some added energy.
Not necessarily. Hermit crab do spend some time sitting to destress or simply take a nap. If a hermit crab is completely unresponsive it may be a number of problems but first check your humidity and temperature as they can be early culprits of inactivity.
Yes, hermit crabs don't usually fight. You could give the new hermit crab a bath so that it smells the same as the other hermit crab in you tank.
