Residency and diel movement patterns of the endangered scalloped hammerhead Sphyrna lewini in the Revillagigedo National Park

Scalloped hammerhead sharks (Sphyrna lewini), an endangered species, exhibit strong daytime residency at two sites within San Benedicto Island of the Revillagigedo National Park, Mexico, with movements into pelagic environments at night. This is the first detailed description of their diel and residency patterns, based on acoustic telemetry data from 11 adult sharks monitored over three years using 58,055 detections by autonomous receivers. The study provides a crucial baseline for monitoring and enhancing conservation efforts in this marine reserve, offering insights into the species' behavior that can inform management strategies.
