"Delving into the Abyss: Unraveling the Secrets of Marine Predators' Deep Sea Dives"

New research using electronic tags and sonar data reveals that large marine predators, such as sharks and tunas, frequently dive into the deep mesopelagic zone, also known as the twilight zone, to interact with its dense layer of organisms for feeding and potentially other purposes. This study highlights the ecological importance of the mesopelagic zone and emphasizes the need for its conservation to prevent irreversible damage. The findings also raise questions about the motivations behind deep diving behaviors and the potential ecosystem services provided by this critical habitat.
