Electric rays (Order Torpedoniformes) represented by 13 species belonging to 4 genera and 3 families are reported from Pakistan. Genus Narcine is reported by 6 species, Torpedo by 5 species and Benthobatis and Narke by 1 species each. Torpedo zugmayeri was described from Gwadar Pakistan by Englehardt (1912) which was generally included in the synonym of T. panthera, T. fuscomaculata or T. sinuspersici, however, during the present study a number of specimens collected from Pakistan were examined and it was concluded that it is valid species. Based on the available specimens, two species Torpedo adenensis and Narcine oculifera are reported for the first time from Pakistan coast. Although no specimen of Narcine atzi from Pakistan was examined but considering its wide distribution in the Arabian Sea and Bay of Bengal, its presence in Pakistan cannot be overruled. There seems to be little knowledge available about abundance and distribution of various species of electric ray occurring in the area. Evaluation of International Union for Conservation of Nature (IUCN) Red listing is available for 11 out of 13 species occurring in Pakistan. Two species Torpedo zugmayeri and Narcine brunnea were not evaluated mainly because, these were included in synonymy of other species whereas one species Benthobatis moresbyi was rated as least concern (LC). Torpedo adenensis was rated as Endangered (EN). Remaining species are considered as data deficient (DD). Considering limited available information, it was stressed to study biology, ecological role in the benthic ecosystem and stock abundance of electric rays from Pakistan.
