Geosesarma is genus of small freshwater or terrestrial crabs, typically less than 10 millimetres (0.4 in) across the carapace. They live and reproduce on land with the larval stages inside the egg. They are found from India, through Southeast Asia, to the Solomon Islands and Hawaii.
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.
Geosesarma contains the following species:
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."
Geosesarma dennerle and Geosesarma hagen, both originally from Java, are threatened by potential illegal over-collecting for the aquarium trade.
