Land hermit crabs are meticulous when picking their shells. Their desire to possess a nice shell can often lead to a hermit crab fight. They may tug on another hermit crab's shell and begin to rap, probe and rock the shell to determine if it's to their liking. They spend most of their life eating, socializing and looking for the perfect shell. Once they find one to their liking, they simply carry and enjoy it until they outgrow it or find another shell that fits their needs. Hermits crabs with shells too small for their bodies often cannot grow as fast and may be more likely to be eaten by their natural predators, which include sharks, fish, octopuses and squid.
