Among the many people who have given me constructive feedback on my website (they are not to blame for any misinformation presented on, I would especially like to thank:

  • Bernhard Picton, Erling Svensen and Frank Emil Moen for their effort helping me identifying many species.
  • Jussi Evertsen at the University in Trondheim for a lot of constructive feedback on my sea slug pages.
  • Marianne Giæver, my wife (who happens to have a PhD in marine biology), for allowing me to spend months and months under water and at the computer, and for having the patience to share some of her knowledge with me.
