Geosesarma malayanum is a species of small red crab which is found in Malaysia. It is famous for its relationship with pitcher plants: as such it is classified as a nepenthephile. G. malayanum is known to visit Nepenthes ampullaria plants and raid the pitchers of their contents. It uses its claws to crush and consume the drowned prey. However it has been reported that the crabs are occasionally trapped by pitchers in Brunei.
