A so-fish-ticated catshark, of the freckled variety!
Scyliorhinus haeckelii are common fr Bahia Brazil to northern Argentina. Freckled catshark live along the continental shelf as deep as 400 m. Filmed at 202 m, offshore of Uruguay and the Rio del Plata during the #AsgardArchaea expedition.
Some of our earliest microbial ancestors, the Asgard archaea, were able to use oxygen, says new study in @nature.com. It may solve a mystery about how complex life first arose.

Sliding into the weekend like this slender fish!
Seen during the #AsgardArchaea expedition, ROV pilots captured this footage at 2,180 m. The international team of scientists collected sediment & water samples in their search for the origins of eukaryotic and complex cells.
The #AsgardArchaea team observed breathtaking wildlife in Uruguayan waters via the cameras on the Schmidt Ocean Institute's deep-sea robot — ROV SuBastian.

I wish everyone could go!
Thanks again to all who made it both possible and such a pleasure, including the Moore foundation, SOI, the Baker lab, and the fabulous crew of Falkor (too).

Yes! I follow @tuexplorer1.bsky.social who posts videos/images from different remote ocean exploration vehicles, literally going where no-one has gone before. the last trip, #asgardarchaea are pix from an expedition to look for new Hodarchaeales off Uruguay

Wow! Radler et al. doi.org/10.1101/2025... These are #asgardarchaea with what? Pseudopodia? Should we call them archaepodia analogously to archaellum? Mindblowing anyway!
That’s a wrap for #AsgardArchaea expedition, w/ @archaeal.bsky.social fr @texasscience.bsky.social! In the coming months and years, this research will likely open the door to new medical breakthroughs and unlock answers to questions about the origins of complex life.

Want to know why UT’s Brett Baker and other scientists are seeking our microbial ancestors in the depths of the ocean? This video from Schmidt Ocean Institute does a fantastic job of explaining!

@schmidtocean.bsky.social just concluded their dives for the #asgardarchaea expedition. Here's what I have for the next one. When they put out the 2026 expedition info I'll share it. Be safe out there, see ya on the next one!
@schmidtocean.bsky.social dive 877 is live. Short last dive for expedition. #asgardarchaea #MarineLife
