Comment:

The ROV used was a Sperre SubFighter 7500 DC of the Sven Lovén Centre for Marine Sciences at the University of Gothenburg. It was equipped with one forward-looking High Definition (HD) video camera (Sony FCBH11, 1920x1080 px, interlaced, 50 fps, 50 Mbps), two standard video cameras for navigation and umbilical surveillance, and one still camera (Canon Powershot G9). Lighting was provided by two 200W HMI lights (Sperre) and two 250W halogen lights. Two parallel red lasers (Deep Sea Systems) provided a reference scale of 5 cm in the videos and photos.

The ROV was piloted by Tomas Lundälv and photos were taken by either Tomas Lundälv or Claudio Richter.

Species were identified by Luisa Federwisch based on their macroscopic characteristics. The image file names include the abbreviated species names; in case of a hyphen it might be either of the two given species (see image descriptions).
