Swarm of Pacific eels is largest group of fish seen in the abyss

Deep-sea explorers have found the largest collection of fish ever seen in the abyssal zone of the ocean, which stretches from 3000 to 6000 metres deep. Footage of more than 100 cutthroat eels on top of an underwater mountain in the Pacific suggests that these areas may be less empty than previously believed.

“This was totally unprecedented for the deep ocean,” says Astrid Leitner from the Monterey Bay Aquarium Research Institute in California.
