''Gecarcinus ruricola'' is a species of terrestrial crab. It is the most terrestrial of the Caribbean land crabs, and is found from western Cuba across the Antilles as far east as Barbados. Common names for ''G. ruricola'' include the purple land crab,〔 black land crab,〔 red land crab, and zombie crab. ==Description==
Four colour morphs exist within the species: black, red, yellow and green.〔 The carapace of ''G. ruricola'' grows in width at a rate of about per year, with the crabs reaching maturity after 5 years, and living for up to 10 years in total. ''G. ruricola'' have a number of adaptations to terrestrial life, mostly regarding water conservation. They are nocturnal, to prevent the hot sun from drying them out. They also have a "nephritic pad", onto which urine is released, in order to be cleaned by microbes before the water is then reabsorbed.〔
