Possible range extension in the endangered and understudied winghead shark (Eusphyra blochii).

Here we report on a possible range extension in the rare and understudied winghead shark (Eusphyra blochii). A specimen was captured by recreational fishermen in Moreton Bay, Queensland, Australia, ca. 800 kilometres south of its current distribution. As winghead sharks show a clumped distribution in Australia associated with river outflow, Moreton Bay, with its large catchment area may represent a suitable habitat for the species and previous occurrence may have gone undetected. Alternatively, climate change may have caused a recent southward shift in winghead sharks, as observed in other elasmobranch species along Australia's East Coast.
