National Geographic has released a trailer for "Hammerhead Sharks Up Close," featuring marine biologist Bertie Gregory exploring Mexico’s Pacific waters.
The program focuses on the critical decline of hammerhead shark populations. By documenting these rare encounters, the series aims to demonstrate how the establishment of protected waters can facilitate the recovery of the species.
Gregory’s work in the Pacific serves as a focal point for the broader SharkFest programming. This seasonal event, which was announced on June 9, 2025 [2], provides an extensive look at apex predators and the environmental pressures they face. The total programming time for the SharkFest season exceeds 25 hours [1].
The trailer depicts the challenges of filming these elusive creatures in their natural habitat. It emphasizes the drivers behind the population drop, while presenting a hopeful narrative regarding conservation efforts. The footage captures the scale of the hammerhead presence in specific Mexican corridors, a rare sight for most researchers.
National Geographic uses the series to bridge the gap between academic research and public awareness. The production highlights the intersection of biodiversity and policy, arguing that targeted protection of migratory routes is essential for the survival of the hammerhead shark.
“The series aims to demonstrate how the establishment of protected waters can facilitate the recovery of the species.”
The focus on protected waters in Mexico suggests a shift toward spatial conservation strategies, where specific geographic corridors are prioritized over general ocean protections to save migratory species like the hammerhead shark.
