Coenobitidae
Land Hermit Crabs, Terrestrial Hermit Crabs
Coenobitidae is the family of terrestrial hermit crabs, comprising approximately 17-18 species in two genera. Adults are fully terrestrial but depend on marine environments for reproduction. Females return to the ocean to release eggs; larvae develop through planktonic zoeal stages before settling. Juveniles acquire empty gastropod shells and migrate to land, where they continue development. The family is distributed throughout coastal tropical regions worldwide.
Gecarcinidae
land crabs
Gecarcinidae is a family of true crabs (Brachyura) adapted for terrestrial existence, commonly known as land crabs. Members possess modified gill chambers called branchiostegal lungs that allow aerial respiration. Adults are primarily terrestrial but require marine environments for reproduction; larvae develop in seawater. The family includes approximately eight genera distributed across tropical regions worldwide.
