New Study Sheds Light on Why Some Animals Dive to The Dark, Deep Sea
Woods Hole Oceanographic Institution
Published: 7 November 2023
A new study reveals large marine predators like sharks and tuna frequently dive into the ocean's twilight zone (200–1,000m), showing its critical role in marine ecosystems and carbon cycling. Scientists call for protection before exploitation begins.
