The occurrence and seasonality of the Critically Endangered great hammerhead shark, Sphyrna mokarran , is data deficient in the Central Pacific region. Using photo-identification and laser-photogrammetry, we describe the seasonal population of great hammerhead

Information on how the trophic ecology of predators shapes their movement patterns and space-use is fundamental to understanding ecological processes across organisational levels. Despite this, studies combining spatial and trophic ecology to determine

Sharks of the genus Sphyrna are under intense exploitation globally. In Brazil’s northern coast, this genus represents a high proportion of fisheries landings and comprises four species. However, due to difficulty of specific identification when specimens
