Male Copulatory Structures in Reproductively Functional Female Live‐Bearing Fish Pseudopoecilia fria We recently discovered a population of the live-bearing fish Pseudopoecilia fria (Cyprinodontiformes: Poeciliidae), in which females were found to possess gonopodia, reproductive organs normally excl...

One of the coolest ichthyology discoveries I’ve heard about in a while. Large pregnant female livebearers with male reproductive organs found in the wild. Goes to show how fluid sex and sexual traits can be.

Wearing a wig and biodegradable beads with okra seeds inside

Happy #MardiGras from New Orleans! I’m wearing my biodegradable beads from the Kato lab 🥼 🧪 @lsu.bsky.social @lsuscience.bsky.social

These beads have okra seeds inside and you can plant the entire chain which is made of microalgae (made in a 3D printer)

The image features a gradient background transitioning from pink to blue. Text reads "Introducing the Trans Bill of Rights" with an icon of a paper and pen.

A colorful infographic titled "What is the Trans Bill of Rights?" outlines four points with icons: protections from employment and housing discrimination, equal access to medical treatment without discrimination, legal recognition of gender identity, and the right to use restrooms aligning with a person's gender identity.

ICYMI: I introduced my Trans Bill of Rights with @markey.senate.gov — legislation to defend trans people across this country as Republicans continue to push anti-trans rhetoric and bills.

To our beloved trans community: We see you, we love you, and we will always stand with you.

Four incomplete fossil fish specimens on a black background. The specimens preserve scales, vertebrae, spines, and so on, and are dark gray on lighter gray to mustard-colored slabs.

Remarkable. Report of a Brazilian spiny-rayed fish dating to the Barremian stage of the Early Cretaceous, preceding the oldest known acanthomorphs by ~20 million years. Gondwanacanthus extends the roots of one of today's most prominent vertebrate radiations: onlinelibrary.wiley.com/doi/10.1002/...

He it’s moi - had a great visit.

Ocean Empire - Science Politics Introducing a new column breaking down seismic shifts in ocean policy and explaining why they matter.

🌊I have a new gig. 🌊

Introducing: OCEAN EMPIRE, my new column about U.S ocean policy and foreign affairs for @sciencepolitics.bsky.social.

We are a brand new online magazine housed at Georgetown University. I'm thrilled to bring in-depth news analysis about what's happening to 70% of our planet.

I’m giving two talks today for the College of Wooster (such a pretty town and campus) one about my research to the department and one to the public about #evolution and why both natural history and the science of evolutionary biology still matter.

Thanks to Phi Betta Kappa for arranging this visit

Awesome and well deserved!

Well the islands moved from the Pacific to the Atlantic with opportunities to connect with Yucatán and now sunken Cayman Ridge.

BREAKING: I just introduced a discharge petition to force a vote on extending TPS for Haiti.

Our Haitian neighbors deserve to continue their essential work & contributions to our communities.

And if Donald Trump won’t act to protect Haitian lives, then Congress must.

Healthy and sustainable fisheries have lower carbon emissions and fuel use, because fish are more abundant and easier to catch with less effort. Rebuilding fisheries and ensuring that fleet sizes are appropriate for catch level, are keys for CO2 reduction

Barbara Theirs discuss herbaria

Anna Monfils discussing training pipelines in collections

At a #ZooMu - Zoo Museum Network: Human Capacity
Workshop - lots of great conversations about the overlap and conflict between zoos (including aquariums) and museums (including herbaria). The differences
go well beyond caring for living versus preserved animals. #naturalhistory

Why This Fish Actually Needs a Hole in the Head

More press for the 'fish with the hole in its head'

Awesome work by @danielgeldof.bsky.social covered in the @nytimes.com

There are a few courses that shaped the trajectory of my career. This is one of them. Take it if you can!

Welcome back, Tigers! Campus wasn’t the same without you. Here’s to a fresh start and a strong spring semester. 🐯✨

Please come join us for @corriemoreau.bsky.social's LSU seminar today at 1pm in Life Sciences Annex A101 on the LSU campus. This includes folks who are still in Baton Rouge following the awesome #SSB2026 #SSB26 meeting!

It's gonna be epic 🐜🧬🌧️🔬🧫🌳!!!

Panelists for the Future of Natural History Collections at the SSB breakout meeting: Brian Smith, Prosanta Chakrabarty, Kory Evans, Corrie Moreau, Ixchel Gonzalez Ramirez, Alison Davis-Rabosky, Jessica Light, Laura Lagomarsino, and Vicens Vila-Coury

Had such a great time hosting the Future of Natural History Collections panel at the #ssb2026 meeting this weekend. Big thanks to @jembrown.bsky.social sky.social for organizing the meeting for @systbiol.bsky.social and for all the amazing panelists who shared so much knowledge and great ideas!

The great @jembrown.bsky.social closing out #ssb2026

It was a wonderful meeting thanks to the hardwork of Jeremy and funding from @lsu.bsky.social and other sources.

Systematic biology is alive and well. Especially proud of all the Global South who attended.

Strong @lsu.bsky.social contingent at #ssb2026 - LSU alumni and current folks

The #ssb2026 at the LSU Museum of Natural Science is going strong!

The wonderful Emily Graslie talking to the #SSB2026 crowd about the importance of natural history museums. She has an art background and became enamored with the University of Montana natural history collections and created the #brainscoop series.

say it again:

4 million people work in higher ed, the largest employer in 10 states, second largest employer in 10 more, and in 60 of the 100 biggest cities

demolishing higher education is economic sabotage
