Abstract
Abstract The rare in the German North and Baltic Sea waters and strictly protected sea star Crossaster papposus was found in 2019 and 2021 during monitoring activities in a marine protected area. This unique observation was achieved by using towed camera platform imagery along a transect in the Fehmarn Belt, which allows monitoring of a much larger area of the seafloor compared to traditional invasive grab and dredge sampling. The last time C. papposus was documented in this area was in 1871, indicating the rarity of this species in the Baltic Sea. Possible explanations for such rare records of the occurrence of this presumably native species in the study region are briefly discussed, including uncommon survival due to salinity conditions caused by prior inflows of saline water from the North Sea.

Oceanological and Hydrobiological Studies is an international journal published by the Institute of Oceanography, University of Gdańsk in Poland. The journal has 4 issues per year and contains papers on all aspects of the marine environment and hydrobiology. All manuscripts are reviewed by editors and independent experts. Based on the referees'' recommendations, the Editor will make a decision on whether to accept a contribution. All articles are published in English. The journal is open to all matters concerning the water environment, thus providing the readers with a wide spectrum of topics in every issue.
