Giant Moray Eel

Giant morays occupy permanent territories in the caves and overhangs of the Wanlitung wall, where reduced fishing pressure has allowed individuals to reach exceptional size — some exceeding 2 meters in length. They are regularly observed emerging from their dens at dusk to hunt cooperatively alongside grouper, a rare interspecies foraging behavior documented here. The reserve's protected status means these animals are habituated to divers and remain in the open far longer than at unprotected sites.
