Habitats
Native to Ecuador and Chile, these hermit crabs live on the Pacific seashore around tidal pools and high-tide zone. Their bodies have adapted to this seashore existence and in captivity, they require access to seawater as they must metabolize the salt in it and bathe in it to maintain gill moisture. Failure to provide access to seawater (real or artificial) will result in death.
Like most hermit crabs they are scavengers and will consume seaweed, dead fish and other detritus that washes up on the shore.
