In June 2015, an individual of Diretmichthys parini (Post and Quero, 1981) was trawled at 530m depth, in the North Sea off Norway and donated to research. This capture, the first for this species in the North Sea was the northernmost recorded so far, and provided an opportunity to document some aspects of the biology and ecology of this data-poor species. This individual was a female, 331mm total length of 33years old, with low mercury content in muscle and liver (~0.

- Deep marine ecosystems, despite being far from pollution sources, can still be affected by contaminants like PCBs, as seen in species of fish and sharks from the Gulf of Lions.
- Significant variations in PCB levels were found among different species, with some like Scyliorhinus canicula showing higher levels, likely due to their unique capabilities in managing these contaminants.
- There's a lack of understanding regarding how individual traits, such as length, age, or diet, relate to PCB accumulation, highlighting the need for more research on bioaccumulation in deep marine fish.
