Geosesarma is genus of small freshwater or terrestrial crabs, typically less than 10 millimetres (0.4 in) across the carapace.[2] They live and reproduce on land with the larval stages inside the egg.

Threats

Geosesarma dennerle and Geosesarma hagen, both originally from Java, are threatened by potential illegal over-collecting for the aquarium trade.[5]
