If you haven't see this incredible footage of a bigfin squid (Magnapinna) from @nautiluslive.org, stop what you're doing & watch! This was from last month's expedition exploring deep waters of the Cook Islands, spotted at 5,100 meters deep. 🌍🦑🌊🧪

Very cool new paper alert! On a 2024 expedition off Chile, scientists saw tons of cusk eels hanging out among tubeworms! An interesting observation of how this species uses methane seeps as important habitat. 🐟🦑🧪🌊 Read the paper: esajournals.onlinelibrary.wiley.com/doi/10.1002/...

It all started with a grand challenge: How can we unlock the potential for ocean life to inspire future technologies? @mbarinews.bsky.social's Bioinspiration Lab has spent years trying to tackle this problem, and we recently developed 4000 m-rated EyeRIS, an in situ lightfield imaging system. 2/n

What EyeRIS revealed was incredible, fine-scale detail of the 3D movements of octopus arms as they crawled over the seafloor completely unconstrained. We learned that octopus crawl by creating a modified foot that persists throughout the behavior, a simplification that could aid roboticists. 8/n

Deep-sea livestreams can inspire wonder and drive action. @schmidtocean.bsky.social's current expedition in Mar del Plata canyon, off the Argentine coast, has become an internet sensation -- just as Argentina’s president threatens to cut and privatize science. 🦑🌊🧪
