description Vampire Crab Overview
Vampire crabs are small, colorful, semi-terrestrial crabs in the genus Geosesarma, several species of which originate on Java and nearby Indonesian islands. Aquarium specimens commonly have dark purple or violet coloration, pale spots, and conspicuous yellow or orange eyes, although appearance varies among species and commercial strains. They require access to both moist land and shallow freshwater, so they are kept in enclosed paludariums rather than conventional fully aquatic aquariums.
