  • 2010: Eubranchus rupium was recorded as a new species for Norway.
  • 2011: Goniodoris castanea and Onchidoris oblonga were recorded as new species for Norway. Tritonia lineata was recorded for the first time in 140 years.
  • 2012: Berghia norvegica was identified for the first time since 1939, and seen in situ by divers for the first time in history. Read more here
  • 2013: A record number of 54 species were identified. Three new species were recorded in Norway for the first time – Onchidoris pusilla, Onchidoris sparsa and Eubranchus doria.
  • 2014: It was determined that a new Flabellina species has to be described. Three new species for Gulen were found – Eubranchus tricolor, Aldisa zetlandica and Doto millbayana.
  • 2015: Two new Doto species never before recorded in Norwegian waters was identified – Doto maculata and Doto dunnei. Work on the Flabellina species is progressing and will likely result in the desciption of two new species.
  • 2016: A new Dendronotus species was confirmed, and inconclusive work to identify the extremely rare Cuthona suecica was done. The Flabellina project continued and will result in three new species being described.
  • 2017: New contributions to science are the discovery of the species Gulenia orjani, Gulenia monicae and Fjordia chriskaugei.


Our house reef at Gulen Dive Resort has probably the highest documented nudibranch species count anywhere in the Atlantic Ocean.
Among our scientific contributions is the discovery of the species Gulenia orjani, Gulenia monicae and Fjordia chriskaugei, all of which were published in November 2017, along with a major revision of the family Flabellinidae.

We have found a staggering 73 species at the Nudibranch Safari since the beginning. Eight of these are marked cf, which is only done when we are certain they are not the regular species (which is then not checked on the list). We try to keep them cf’s to a minimum, but over the years, we have inevitably accumulated a few.

Scientific fieldwork

There are several things to know about Nudibranchs and the experts who hold the lectures on the Nudibranch Safari are seasoned scientists. Often, the trip is part of their scientific fieldwork, and meticulous notes are taken down when they study the collected nudibranchs in close detail. They will all help you to build up a unique understanding of the subjects during the Nudibranch Safari.

Current position is Head of Department, which also allows time for research and teaching.
Main research fields are biosystematics and biogeography, particularly of polychaete worms (Polychaeta). I also have a great interest in nudibranch molluscs (Nudibranchia). My research is focused on phylogeny, taxonomy and biogeography in these groups, as well as faunistics and biodiversity of marine invertebrates along the Norwegian coast.
