I was supposed to present my research on deep-sea sharks in the western Caribbean Sea at #SI2026, but I was, er... let go from my job shortly before the conference and am not there. Since I gained a few followers from this, I thought I would share some of what I would have presented yesterday (1/9)

What’s driving the decline? The crisis isn’t just fishing — it’s invisible fishing. Much shark & ray catch is under-reported, aggregated, or mislabeled, masking real mortality & delaying management. What we don’t measure, we don’t manage. @cgmull.bsky.social @nathanpacoureau.bsky.social

🚨 NEW PUBLICATION 🚨 Today in @currentbiology.bsky.social, we found that 30 species of #sharks, #rays, and #chimaeras overlap with proposed #deepseamining in Areas Beyond National Jurisdiction #ABNJ - over 60% are already #threatened with #extinction 🦈 📸 Blue Planet Archive / Masa Ushioda

New paper led by @seaprinceaaron.bsky.social in @currentbiology.bsky.social looking at the threats deep sea mining poses for sharks, rays, and chimaeras. We found 30 species are threatened via various pathways including collector impact and plumes at depth and pelagic discharge plumes.

I don't think many people realize that Canadian companies own something like 75% of the mines in the world.

In this episode of our podcast, Brandi Morin, a Cree-Iroquois-French environmental journalist and freelancer for Mongabay, discusses how Canadian mining projects impact ecological health and the rights of Indigenous communities in places such as Ecuador and Bolivia.
