Geosesarma is genus of small freshwater or terrestrial crabs, typically less than 10 mm (0.4 in) across the carapace. [2] They live and reproduce on land with the larval stages inside the egg. They are found from India, [3] through Southeast Asia, to the Solomon Islands and Hawaii. [2]
In the pet trade, they are sometimes called vampire crabs. This has nothing to do with their feeding habits, but rather with the bright, contrastingly yellow eyes of some Geosesarma species. [4]
Geosesarma contains these species: [5]
As of March 2015, professor Peter Ng of National University of Singapore has named 20 Geosesarma species, and he "has another half a dozen or so newly collected Geosesarma species from Southeast Asia in his lab, and these species still need to be named and described." [4] [7]
Geosesarma dennerle and Geosesarma hagen, both originally from Java, are threatened by illegal overcollection for the aquarium trade. [8]
