Geosesarma malayanum is a species of small red crab which is found in Malaysia.[1] It is famous for its relationship with pitcher plants: as such, it is classified as a nepenthephile.[2] G. malayanum is known to visit Nepenthes ampullaria plants and raid the pitchers of their contents.[1] 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.[1]
