The distribution of five Rhino rays viz., Rhynchobatus australiae, Rhynchobatus laevis, Rhinobatos punctifer, Glaucostegus granulatus, Rhinobatos lionotus and twelve sting rays such as Himantura leoparda, Himantura undulata, Himantura tutul, Maculabatis arabica, Neotrygon indica, Pastinachus ater, Pastinachus gracilicaudus, Pteroplatytrygon violacea, Pateobatis fai, Pateobatis bleekeri, Taeniurops meyeni and Urogymnus asperrimus is reported. Further, based on spotting patterns recorded on dorsal surface and contour of ocellae, five morphotypes of Himantura leoparda, and two of Himantura tutul are illustrated. Observations on six species (Rhinobatos punctifer, Rhinobatos lionotus, Himantura undulata, Himantura tutul, Neotrygon indica and Pastinachus gracilicaudus) is given.
