Crab Your Attention: Dive into the Unique Characteristics of Hermit Crabs

Hermit crabs, which belong to the subphylum Crustacea, possess several unique characteristics. As with most crustaceans, hermit crabs have a fused head and thorax, forming a structure called the cephalothorax, which is covered by a protective shell called the carapace. This contributes to their body plan comprising two sections: cephalophorax and abdomen.

Additionally, hermit crabs have a chitinous exoskeleton that is shed by molting and ecdysis anytime the animal needs to grow or progress to a new stage of development. The exoskeletons of many aquatic species, including hermit crabs, are also infused with calcium carbonate, providing additional strength. This unique feature sets them apart from other crustaceans.
