TL;DR: Two new species of the nudibranch genus Dendronotus are described from the Arctic and North Pacific oceans respectively, based on morphological and molecular data, and the North Pacific Dendronsotus albus is revealed to be a species complex.

TL;DR: These findings are consistent with the hypothesis of geographically restricted spawning in G. fabricii and found evidence for one new breeding area in south-eastern Greenland, and spermatophore size showed a uniform increase in relation to increasing male size.

TL;DR: A pleuroproctic anal opening is an important basal character of the group Nudibranchia and the family Aeolidiidae is discussed in the light of the present discovery.

TL;DR: Stauroteuthis syrtensis and C. muelleri were studied based on representative material collected in Greenland, Iceland, and the Barents Sea and adjacent deep-sea areas as mentioned in this paper .

TL;DR: In this paper, the authors collected data from 12.569 fish assessment trawls and associated bottom water temperature data to identify areas with high proportions of sessile and upright taxa, taxa with calcareous skeletons that may be susceptible to ocean acidification, and 'cold-water' taxa that are most vulnerable to ocean warming.
