Bryozoans were collected in Kongsfjorden (79°N and 12°E) in the summer seasons of 1997, 1998, and 1999. In the total of 44 grab, dredge, and SCUBA diving samples 143 taxa were determined: 123 species, 17 to the generic and 3 to the family level. In the investigated material were 24% Arctic species and 66% boreal-Arctic species. This suggests a rather Arctic nature of the fjord. A few boreal species indicate the influence of warm water masses (West Spitsbergen Current). The majority of species (76%) have an encrusting life form. There were 5 species with a frequency of occurrence higher than 20%. These are Electra crustulenta var. arctica (31.82%); Cylindroporella tubulosa (27.27%); Tegella arctica (22.73%); Tegella armifera (20.45%); and Hippothoa divaricata var. arctica (20.45%). Among all identified species 23 were recorded for the first time in the area of Svalbard archipelago. Most (79%) of newly noted species have Arctic distributions. The lower sampling effort of previous researchers most likely accounts for the present enrichment of the list of Bryozoa of Kongsfjorden.

W Arktyce wszystkie organizmy żywe mają trudne warunki, jednak chyba najtrudniejsze mają te, które próbują przetrwać w strefie przyboju, uczepione smaganych przez wodę, wiatr i lód kamieni.

All living organisms face difficult conditions in the Arctic, but those which attempt to survive clutched to seafront stones, where they are lashed by water, wind, and ice, may face the toughest conditions of all.

Thirty-two species of echinoderms from epibenthic sledges, dredges, scuba diving, and other samples (in total: 467 samples and c. 20 000 specimens) from fjords and coastal waters off Spitsbergen were analysed between 1996 and 2014. The most numerous group of echinoderms in the coastal waters off Spitsbergen is brittle stars (78% of the total individuals). The echinoderms do not form any clear assemblages according to depth or distance from glacial sedimentation and substrate. Some species prefer hard bottom (Strongylocentrotus droebachiensis) or water free from glacial suspensions (Ophiopholis aculeata). In contrast to the species listed above, we also found opportunistic species such as the starfish Urasterias lincki and the brittle star Ophiocten sericeum. These two species are distributed quite uniformly, regardless of the environmental factors. The majority of the species prefer a soft bottom below 200 m.
