    Abstract

    Three specimens of the porcupine ray Urogymnus asperrimus (Bloch & Schneider, 1801) are reported from Heron Island on the Great Barrier Reef, Qld. These are the first records from the southern Great Barrier Reef and represent the southernmost records for this species on the east coast of Australia. An immature male with a disc width (DW) of 650 mm and two females measuring 620 mm DW and 545 mm DW were caught on the eastern side of the island using hand or seine nets. The two females were released alive after examination. Some morphometric data from two of the individuals are provided. The distribution, biology and ecology of this species are poorly-known, with only five catalogued Australian specimens held in Australian museums. The majority of these are not whole specimens and are in poor condition. There is further scattered information from photographs and live sightings. All known Australian records of U. asperrimus are summarised here. There are records of the species across tropical northern Australia, from Ningaloo Reef, WA (22°43′S) to Heron Island, Qld (23°26′S).
