Dorado Octopus (IMAGE) Bigelow Laboratory for Ocean Sciences Caption Deep-sea octopuses brood their eggs on rocks at the Dorado Seamount offshore of Costa Rica, almost two miles below the ocean surface. Deep-sea ecosystems like these are threatened by emergent human activities like deep-sea mining. A $2 million project led by Bigelow Laboratory will help an international group of scientists find out. Credit Photo courtesy of Woods Hole Oceanographic Institution. Usage Restrictions Fair use.
