C. clypeatus uses the majority of it is time in the woods it is proven to go higher sand hills nearby the coast (Sterrer 1986). Since C. clypeatus has actually gills it ought to live in regions of higher humidity. But their gills don’t let them to be totally submerged under water as hermit crabs often block. C. clypeatus is known to search across a number of habitats and you can provides mounted slopes as much as 887 m (Walker 1994). From inside the Bermuda this type of crabs just after roamed throughout the isle however, today they are merely know so you’re able to live in Hungry Bay a little bay towards the south coastline of island (Hass 1950; Walker 1994).

There are four stages regarding molting, pre-molt (proecdysis), molt (ecdysis), post-molt (metecdysis), and you can intermolt (anecdysis) (Wood 2007).
Ecdysis is the shedding of your exoskeleton, to date the latest crab is quite vunerable without the defense off a painful exoskeleton. Metecdysis is the process of hardening this new exoskeleton; the crab commonly eat the old exoskeleton to add calcium supplements into brand new exoskeleton. Anecdysis is the periods inside the-between molts where the crab progress times to prepare on next molt (Wood 2007).
