Many characteristics define the hermit crab. With the large shell it carries on its back being regularly replaced by larger shells as it grows, the hermit crab molts as it sheds its skin regularly. Therefore, it burrows away and hides for about one month at any time while it grows its replacement exoskeleton so it becomes reclusive hence the name ‘hermit’ crab. With six legs, hermit crabs climb easily.
What characterises the hermit crab best is the large communities and colonies they live in. Whether climbing, burrowing, scavenging or playing your hermit crab is never solitary as there are always members of the family group in close proximity. Most hermit crab enthusiasts keep them together as groups.
