Hermit Crab In The Sea Royalty-Free Stock Photo

Hermit crab is the common name for all crabs of the families Paguridae and Coenobitidae order Decapoda of the class Crustacea. These crabs use empty snail shells e.g., whelk or periwinkle or other hollow objects as a shelter for partial containment and protection of the body. Their bodies lack a hard protected carapace; without a shell they are extremely vulnerable to predators.
