The Neverending Bamboo Coral Story

09.10.2025

Cruise diary:  At 6:20 on Tuesday 30 September, the remotely operated vehicle (ROV) Ægir6000 landed on the crest of an underwater ridge on the Arctic Mid-Ocean Ridge (AMOR) in the middle of the Norwegian deep-sea in search of a bamboo coral garden.

The image shows a bright red fish with connected fins swimming over a seabed in light and dark shades. A close-up of a small crustacean in a cave has been inserted, these animals are what create the light areas. The crustacean may resemble a lobster.
