Modified Shells

Hermit crabs are constantly working. They always have something to do whether it is to eat, climb, dig, drink, molt, find new shell, sleep, explore or modify their shell. When your hermit crab is withdrawn in its shell it might be modifying the shell. Hermit crabs like to perfect the insides of the shells they wear, which is why the modify them. A hermit crab can modify its shell in a few different ways, one way in to remove the insides. Removing the insides of shells makes the shell more comfortable for hermit crabs which is why they work on removing them over a long period of time. I tried to get a picture of a modified shell to show what one looks like but it is very hard to get a look into to the shell. In the picture below you can kind of see how the structures inside of the shell are gone which is liked by hermit crabs. Another way a hermit crab can modify its shell is by trimming the outer edge of the shell to make moving in and out of the shell easier, or make movement easier.
