Previously, giant water bugs (Belostoma sp., Belostomatidae) were thought to be the only predators of the cave-dwelling fish Poecilia mexicana (Poeciliidae) in a southern Mexican sulphur cave (Cueva del Azufre). Here, we report on three species of Araneae [Ctenidae gen. sp., Tinus sp. (Pisauridae), and Hemirrhagus pernix (Theraphosidae)] from that cave, which also prey on P. mexicana. To our knowledge, this is the first report of spider predation on a cave fish.
