Happy to share our new preprint led by @annaschreck.bsky.social with @micrott.bsky.social and Ivan Cepicka which capitalized on the rare opportunity to compare the genomes of closely related symbionts associated with animals vs. protists.

I’ve been live-drawing the science being presented at Squid Vibrio 2026 as comics during the talks.
Today’s keynote from @symbiosisrox.bsky.social was super cool, all about bacterial symbionts in cold seep and hydrothermal vent animals.
Here’s the comic!

Excited to share that @michelle-hauer.bsky.social's paper with @katiekliermicrobe.bsky.social @maggielangwig.bsky.social @karthik-a.bsky.social on phage interactions with chemosynthetic symbionts was published today. #NSF and @schmidtocean.bsky.social supported. academic.oup.com/ismecommun/a...
Widespread symbiosis of ciliate epibionts colonizing gills of shrimps inhabiting vents and seeps across the Pacific Ocean biorxiv.org/content/10.64898/2026.02.27.708428v1.full #symbiosis #protists
Led by #URIGSO @symbiosisrox.bsky.social lab, the expedition used #ROVJason & #AUVSentry to understand how hydrothermal vent ecosystems have fared following ash impacts from the 2022 Hunga eruption and how these communities recover after major disturbances.

New preprint about closely-related #methanogens living inside ciliates and animal guts!!
We found that ciliate symbionts are functionally indistinct from free-living spp, while gut symbionts have streamlined genomes encoded for scavenging. read on if you're curious why 🤔 #ProtistsOnSky #SymbioSky
Abstract. Deep-sea hydrothermal vent ecosystems are sustained by chemoautotrophic bacteria that symbiotically provide organic matter to their animal hosts
