First record of the smooth hammerhead shark (Sphyrna zygaena) in Saint Peter and Saint Paul Archipelago: range extension for the equatorial region

A smooth hammerhead shark ( Sphyrna zygaena ) was found in Saint Peter and Saint Paul Archipelago in May 2015. This is the first confirmed occurrence of a smooth hammerhead shark in an equatorial oceanic island and suggests a geographic range extension for the species.
