Habitat
Strictly coastal tropical environments including beaches, mangroves, and inland forests. require humid terrestrial conditions with access to freshwater sources. All life stages depend on proximity to ocean for and larval development.
Distribution
Coastal tropical regions worldwide, including Indo-Pacific, Atlantic, and Caribbean shorelines.
Life Cycle
hatch in seawater; larvae pass through multiple planktonic zoeal stages and a megalopa stage in marine environment. Megalopae settle, obtain gastropod shells, and migrate to land.

Behavior
are strictly terrestrial but require shell-carrying for protection; megalopae actively seek and co-opt empty gastropod shells before land .
Ecological Role
Scavengers in coastal terrestrial ; contribute to nutrient cycling and seed in some . Shell acquisition creates competition with other shell-using organisms.
Human Relevance
Popular in pet trade; some collected for food in certain regions. degradation and shell availability limits affect .
