  • Title: First sighting of a tropical benthic reef shark species at Rapa Nui: chance dispersal or a sign of things to come?
    Author: Morales N, Coghlan AR, Hayden G, Guajardo P.
    Journal: J Fish Biol; 2019 Aug; 95(2):642-646. PubMed ID: 30963562.
    Abstract:
    On 20 December 2017, a mature Triaenodon obesus was observed at Hanga Roa Bay, Rapa Nui (Easter Island) at c.18 m depth. This observation increases both the range of T. obesus in the Pacific Ocean and the number of elasmobranch species at Rapa Nui. In combination with other recent sightings further extending the southern range of this species during the Austral summer, sea surface temperature is suggested as key to southern dispersal.
