🌊 New research out now in ICES Journal of Marine Science!
Using #OneBenthic, we reveal large-scale spatial patterns in marine epifaunal communities. One of four #Cefas papers under OWEC POSEIDON.

Fantastic visit to Cefas this week, chatting with herring experts and channeling our inner ‘Raiders of the Lost Archives’ 📖🐟

📢New paper!

🐟📚Using fish stomach contents spanning over a century, we reveal long-term diet shifts (from larger bivalves to smaller opportunistic prey) in demersal fish species in the western North Sea.

In 2025, an explosion of common octopus appeared across the southwest coast of England

Dr. Keith Hiscock, MBA, explains what led to this “octopus bloom”, how it connects to long-term changes in our seas, and what it could mean for the future of UK marine life.

Did someone say it's take an octopus to work day?

Brilliant photos from @akwildlifefalmouth showing the extent of the octopus surge in the southwest. This Risso's dolphin seemed to be having fun 🐙
I get that the news cycle is packed right now, but I just heard from a colleague at the Smithsonian that this is fully a GIANT SQUID BEING EATEN BY A SPERM WHALE and it’s possibly the first ever confirmed video according to a friend at NOAA
