Another successful #oceanx #YoungExplorersProgram in the books! This was a really fun group of students to teach about #eDNA as we sailed from #GranCanaria to the #Netherlands 🧬🌊

Former NOAA officials warn that job cuts could risk lives and livelihoods NOAA is best known for operating the National Weather Service, but its work stretches from the ocean bed to outer space and supports billion-dollar industries.

Red-finger aeolis #nudibranchs spotted sharing a romantic hydroid dinner off Portsmouth NH for #molluscmonday and belated #valentinesday 🦑

Most of the money that researchers spend is on paying other researchers. In other words, canceling research funds is taking money out of local economies by removing people and their spending power from them. 🧪

An Atlantic Ancula (𝘈𝘯𝘤𝘶𝘭𝘢 𝘨𝘪𝘣𝘣𝘰𝘴𝘢) near the mouth of the Piscataqua River off Peirce Island (Portsmouth, NH) for #molluscmonday

This was one of those shots you can’t believe actually turned out because the algae was swaying back and forth so much! #marinelife #macrophotography

A little spot of sunshine on an otherwise sad day for the planet #molluscmonday #planetoverprofit

Rim-backed nudibranch (𝑃𝑎𝑙𝑖𝑜 𝑑𝑢𝑏𝑖𝑎) in New Castle, NH yesterday #marinelife

Happy #MolluscMonday 🐌

The Jonah crab, Cancer borealis, is integral to marine ecosystems, supports a valuable commercial fishery in the northwest Atlantic Ocean, & is an established model for neuroscience research.🦀

Important piece by Gittleman - “It’s impossible to separate human health from health of the natural world. Ecology is the unifying science that integrates knowledge..[the] One Health approach is unlimited, exciting, & necessary for the health of life on our planet” www.pnas.org/doi/10.1073/... 🧪🌎🌐🌾

It’s almost nudibranch season here in New England! These beauties are the reason I started drysuit diving #nudivember Photo of a Flabellina nudibranch taken in March at Peirce Island, Portsmouth NH #marinelife #coldwaterdiving #underwaterphotography

That would be awesome! I’d love to be a contributor to the Marine Life Feed

Very adorable but very lost 😍
Spotted this juvenile Short Bigeye giving #FindingNemovibes on my last dive in #GloucesterMA. This tropical/subtropical species is typically found between Brazil and North Carolina, so it was a rare sighting this far north!

Genomic signatures of exceptional longevity and negligible aging in the long-lived red sea urchin Lifespan varies enormously across the animal kingdom, with some animals attaining exceptional longevity.

This study is officially old news since it was published back in April, but I’ve decided it’s worth resharing for my first Bluesky post!

They said that sea urchins couldn't have a bluesky account because we "don't have thumbs." We have hundreds of tube feet, we can push a few buttons 😤
