Arrival of an Australian anguillid eel in New Zealand: an example of transoceanic dispersal

摘要: Anguilla reinhardtii, hitherto known from eastern Australia, New Caledonia, Norfolk Island, and Lord Howe has recently been discovered in rivers of northern Zealand. Identification, based on morphological genetic characteristics, is unequivocal; eight consecutive year classes have found. The only reasonable explanation this occurrence transoceanic dispersal to Zealand, probably subtropical oceanic spawning grounds north This corroborates past hypotheses that the strongly diadromous freshwater fish fauna Zealand derived by marine life intervals.
