The nudibranch species Tenellia adspersa (Nordmann, 1845) is recorded from the Finnish archipelago for the first time in more than 100 years, as previous records of this species from the Baltic proper are few and date back prior to 1900. The present record was made by means of SCUBA diving at near-shore brackish water locations. Despite only a few early records from the literature, the new data presented here suggest that this species is abundant in the northern part of the Baltic proper. A short account of ecological observations of T. adspersa from the Northeast Atlantic is given, indicating that together with the present abundance, this highly adaptable species is fully capable of thriving in true brackish water conditions. 4 pp., 2 figs, gr. 8.
