It will grow back during the next molting period. (Pretty cool!)
More information: Actually, it is a sign that your hermit crab is very stressed. If he survives, the leg will grow back during the next molting period. If you've had him a while, you need to check yoru tank conditions and think about whether he's been dealing with a lot of extra stressors lately, such as being roughly handled, or if his living conditions are not as he needs them to be. Hermit crabs are wild caught animals, so the stress of being taken from their home environment and shipped to pet stores is stressful. Also, many pet stores do not keep their own crabs in proper environments with regulated temperature and humidity, and are often in enclosures where people can actually reach in and pick them up and touch them and they are often not careful with the poor things, causing more stress. You didnt say how long you've had your crab.
When you bring home a hermit crab, he needs a terrarium type cage with a regulated temperature between 70 degress minimum and 85 degrees max. More importantly, the humidity needs to be kept near 70%. Hermit crabs breathe through modified gills, which need moisture to work properly. Too dry for too long and their gills dry out and eventually they suffocate over time. Your hermit crab will be sluggish and slow moving because he's not getting enough air.
He also needs to be left alone for about 2 weeks when you bring him home, so he can de-stress. Picking him up a lot after bringing him home can add more stress after the ride home, and he can lose legs or die. As long as you have enough substrate for him to burrow into and mellow out, hopefully he will be okay.
yes
It depends on how healthy the hermit crab is in my opinion
There is not one person who has a hermit crab with a missing leg. I found a hermit crab with a missing leg and even though the store keeper told me that he had a missing leg I still felt I had a bond with him. If you do get a hermit crab with a missing leg you just have to wait until it molts. Once it molts the leg will grow back and it will be like it never had a missing leg in the first place.
you don't need to do anything a hermit crab will do it itself. if a hermit crab losses a leg it will grow back. it will grow back after molting.
I actually did get pinched by a hermit crab earlier today. I did not do anything . You probably felt a little sting but you do not have to do anything. (to prevent any pinches keep your hand flat as you can when you hold your hermit crab)
Yes, but it will die soon.
Yes, a hermit crab will grow its let back if it has lost one when it molts. It's easier to see if your hermit crab has signs of molting. If its lost a leg you will see that the leg will start to turn into a gelatin like substance. Which tells you its going inot the stage of molting.
You can if you want to, but you can actually keep it in there and let it serve as another food choice for the hermit crab.
The two most common growths on a hermit crab are a molt sack, which is a dark looking spot on the side of a crab where they store nutritious goo aimed at helping them survive their molt. the other one is a gel limb. When the hermit crab loses a leg or claw, they often grow a small translucent nub called a gel limb where the repacement will be.
they loose their legs like we loose teeth
Yes hermit crabs do have feet, it is the little segment at the bottom of their leg. But if it is missing don't worry it will grow back the next time it molts.
It is ok for your hermit crab to lose only one leg in a certain amount of time but if your crab is losing more than one leg a nite put them in an isolated tank because there is a chance your crab may be dying.
