Distribution and remarks: Eubranchus scintillans is a newly described species which was until recently considered a colour form of E. exiguus ( Grishina et al. 2022) . Recent records of the species are therefore few although Grishina and co-workers noted that both species occur together in the Barents and the North Seas ( Grishina et al. 2022). In Tromsø, E. scintillans was found to be a commonly occurring species. Animals were found at all seasons of the year and were mainly found associated with Obelia hydroids growing on Saccharina latissima . The present records are the first records of E. scintillans in the Tromsø region.
