New biogeographical information on Queensland chondrichthyans

Abstract

New information is presented on chondrichthyan fishes. Mobula japanica (Müller & Henle, 184) is reported for the first time from Australian waters from two specimens, one from Lake Macquarie, New South Wales and one from Fraser Island, Queensland. Squaliolus aliae Teng, 1959 and Asymbolus analis (Ogilby, 1885) are reported for the first time from waters off Queensland, and aspects of the biology of A. analis are discussed. Significant southern range extensions are reported for Aetomylaeus nichofii (Schneider, 1801) and Dasyatis leylandi Last, 1987. Southern range extensions are also reported for Carcharhinus amboinensis (Müller & Henle, 1839) and Carcharhinus cautus (Whitley, 1945) and these species are recorded for the first time from Moreton Bay. Northern range extensions are reported for Hypnos monopterygius (Shaw & Nodder, 1795) and Orectolobus maculatus (Bonnaterre, 1788). Comments are also made on the distribution of Dipturus australis (Macleay, 1884) and Myliobatis hamlyni Ogilby, 1911.
