New paper out in Genome Biology and Evolution!
Genome Skimming Illuminates Hidden Species Diversity and Symbiodiniaceae Associations in East Pacific Pocillopora Corals

Genome skimming yields thousands of loci, recovering mitochondrial genomes and nuclear markers.

Other benefits are higher phylogenetic resolution, success with degraded samples, and compatibility with future bait sets (i.e., future-proof).

A global coral phylogeny reveals resilience and vulnerability through deep time - Nature The most recent common ancestor of the stony coral Scleractinia dates to about 460 million years ago and was probably a solitary, heterotrophic and free-living organism.

New Nature paper!

Vaga et al. (2025) reconstruct a time-calibrated phylogeny of stony (scleractinian) corals, which suggests that some could be resilient to climate change.

Congrats @claudiavaga.bsky.social

This is really cool. I’ve seen some of the similar mesopelagic fish carbon work - great to see equivalent estimates now for cephalopods!

Meme of Japanese spider crab. It's a red crab with cartoonishly long claws on a black background. Text: "This Tuesday has been exceptionally long. Please send thoughts, prayers, and treats to a very tired Reginald "

#CrabAZ never ignores memes. M is for Macrocheira.

This is both the largest arthropod alive (3.8 m or 12 ft leg span, only males are this extreme) and the only living species in its family. Mainly found in Japanese waters up to 600 m depth.

(Yes we know it's Thursday, sorry)

"Funding for taxonomy makes sure that existing collections of undescribed specimens are properly studied, cataloged, and made accessible to researchers world wide" - Dr Jini Jacob

Meet Dr Jacob, currently documenting over 60 new nematode species 👇

It’s not #WormWednesday but check out those beautiful drawings of echiurians and sipunculans drawn by Ikeda, from 1904!! Also just saying « I don’t know » was done so elegantly. Reading old taxonomy papers is so so cool!!

💙 Finding "the one" is difficult, but in the dark, deep ocean, it’s even harder.

From the fascinating relationships of anglerfish to the use of bioluminescence to attract mates, the deep ocean holds some unique love stories. 💙

Happy #InternationalDayOfWomenAndGirlsInScience! 🌊 At the MBA, we’re proud of our diverse team of female scientists whose groundbreaking research is shaping the future of our ocean.

Dive into our latest update to explore the journeys & career advice of our female Research Fellows ➡️ buff.ly/3WYFjYK

Today, on #InternationalDayofWomenandGirlsinScience, we proudly celebrate the incredible women pushing the boundaries of ocean science and deep-sea exploration. ODL is a female-founded and led organization with a team of 80% women, and we work to make ocean exploration more accessible to all.

Deep sea mystery: does anyone know what this weblike structure is that we say on the deep sea corals today during the ROV dive? What forms it? 🌊🪸🐟🦀🦑

Do you love the deep sea? I do! So happy to partner up with @dsbsoc.bsky.social, check out their page filled with fascinating info! #STEM #deepsea #writingcommunity #kidlit #amwriting #amreading #edusky

Life brings cool surprises, like this curious skate who DECIDED to turn around and explore ROV SuBastian 😊. Have a new year full of good surprises🍾 🌊!
This happened while we explored hydrothermal vents in the Pacific on my second expedition aboard R/V Falkor (too).

Right: Close-up of skeletal spines that have little bumps or tubercles, small surface features on the spines used to identify black coral species.

We use scanning electron microscopes to image skeletal features, which are used to identify or describe new species.
