Climate-driven shifts aren't just happening at the surface. Using 26 years of data, we show that deep-water sharks and chimaeras are moving northward into Arctic waters🦈 Their prey are moving too, suggesting that the entire deep-sea community is on the move. Read it here👉 doi.org/10.1371/jour...

@lottesdahlmo.bsky.social at #SI2026 : Climate change impacts how much oxygen is in seawater, which impacts spiny dogfish sharks in Norwegian Fjords. They can’t enter their preferred deeper habitats because of low oxygen levels.
