 The reticulate whipray is closely related to H. undulata and H. leoparda , which share much of its range . All three species are very similar in size , shape , and color pattern , resulting in a long history of taxonomic confusion that only recently is starting to be untangled . In 2004 , Mabel Manjaji described the ' uarnak ' species complex , containing H. fai , H. gerrardi , H. jenkinsii , H. leoparda , H. toshi , H. uarnak , and H. undulata , plus three more undescribed species . The reticulate whipray itself varies in appearance throughout its range , and further taxonomic comparisons are required to determine whether its spotted and reticulated color morphs in fact represent different species . Alternate common names for this ray include coachwhip ray , leopard stingray , longtail stingray , and marbled stingray ; some of these names are shared by other , similar species .
