That’s weird! I would have kept the whole raccoon, or chopped off its head for a teaching specimen. But I am curious what RFK learned later…

I’m holding the Senate floor tonight in protest of legislation that would allow a copper-nickel sulfide mine on the doorstep of the Boundary Waters. Not this mine. Not this place.

Ok then, just submitted our taxes pretty much at the last possible minute, as straight-up nauseatingly honest as always. And as always, I demand and expect that our funds will be spent wisely on behalf of the interests of the people of this country and to help others around the world. 😎

My latest for @sciam.bsky.social is all about the real biology, ecology, and climate science that is used to create the world of Pokémon, and how scientists use it to teach science in the real world. This is just about the most fun I’ve ever had interviewing anyone, and I hope you enjoy! 🧪🌎

Almost finished pruning this Bradford Pear tree. How’s it look so far?

It’s all fun and games until the fish go away www.noaa.gov/news-release...

Understood the assignment!

Tierney Thys was truly an amazing advocate for the oceans and for the wonderful ocean sunfish, Mola mola, and its relatives. A grad school friend in the Wainwright lab at Duke, truly saddened to hear that she is gone. Great tribute by her sister. 🐟🧪🌿🦑 thys-danielle.medium.com/the-ocean-le...

New barracudina just dropped 🎉 We see a LOT of these long, toothy deep sea fishes in our swordfish stomachs - exciting to be able to ID them more accurately in the future! www.fisheries.noaa.gov/feature-stor...

Coralheads that have tuned into the CCC the past couple of mornings have been treated to a rainbow parrotfish party 🥳🌈🌈🦜🐟🪸🎊 #rainbowparrotfish #parrotfishjungle #parrotfishcapitaloftheworld #parrotfish #coralcitycamera

My department at CSU Northridge is hiring a vertebrate functional morphologist! We've got a great EEB group, and we're looking for someone to carry forward a tradition of enriching organismal courses and community-engaged research. App review starts March 15 csucareers.calstate.edu/mob/cw/en-us...

The new computational model for jaw mechanics in piranhas is called PiranhaLever, available for download on my GitHub github.com/mwestneat/Pi.... Along with various other models for biomechanics and morphometrics. All Mac apps, install the dmg and skirt your security demon 😎

Piranha bite force and tooth stress are fantastically high for their size! Check out our new paper on computational modeling of the cranial muscles and bite mechanics of the amazing piranhas. #biomechsky 🐟🧪🌿 link.springer.com/epdf/10.1007...

Neil H. Shubin has been elected as the next NAS President! A leading evolutionary biologist and science communicator, Shubin will succeed Marcia McNutt on July 1. The Academy also named Cherry Murray as International Secretary and elected new councilors. Read more: www.nasonline.org/news/2026_pr...

Proud graduate of this awesome course in 2000- Highly recommend!

New @jexpbiol.bsky.social paper alert! The grips of hawks and owls on their often struggling prey are strong! Check out our new paper led by Alex Clark and with @linnealungstrom.bsky.social. Alex with the cover photo 🧪🌿🦉 #Biomechanics #AerialFishes journals.biologists.com/jeb/article/...

We are doing a food drive across multiple Departments and programs at UChicago. Our box in Culver Hall for Organismal Biology and Anatomy is now greatly overflowing 🤙 To the food pantries soon!

NSF is open again! A few comments: *Please be patient. During a shutdown NSF employees cannot open computers or respond to emails. *Merit review will continue. However panels won’t resume until after Dec 8th. *POs remain excited and committed to advancing science and the scientific workforce.

Happy Halloween! We are THE haunted Harper Ave block in Hyde Park, and will serve candy to thousands of South Side Chicago kids tonight! I have a bunch of cool skulls out in the yard but the baseball graveyard is the most popular. 😆

Seems like the L flag was bad luck. Brewers are now 0-3 after using it to celebrate their opponents loss. Oops.

ICB From the Evan's lab! Developmental and Functional Interactions Structure Patterns of Variational #Modularity in the Lunar #Wrasse Skull by Hugi,& @sternarchella.bsky.social et al doi.org/10.1093/icb/... Evans lab koryevans.weebly.com/people.html

Our killer team of @mfarjo.bsky.social, Ryan Isdonas, Andrew George, and @mwestneat.bsky.social found: 🐠head/body shapes are related to diet 🐠fishes have pairs of high/low aspect ratio propulsive fins (caudal/pectoral) 🐠caudal fins have the highest evolutionary rates & covary with body/pectoral fins

So excited to see our paper on #phylogenetics and #morphometrics integrated with feeding #ecology in the surgeonfishes by @linnealungstrom.bsky.social get posted, her first in a series on their incredibly cool biology. 🐟🦑🧪🌎🌿

No better reason to join Bluesky then to say the first chapter of my PhD is out as a preprint! New surgeonfish phylogeny, ecomorphological relationships, evolutionary shape correlations-with NEW method to accurately account for phylogenetic covariation among shapes! www.biorxiv.org/content/10.1...

Seems worth noting this award in light of the present circumstances. Get the troops out of our fair city please, perhaps after they enjoy a great Malnati’s pizza!

Aren't they lovely? Congratulations to my great colleague Bud Freeman, this is the culmination of over a decade of work! www.mapress.com/zt/article/v...

It’s a start, congrats to our Harvard colleagues! www.cnn.com/2025/09/03/p...

I'm aware that the President likes to go on television and beg me to call him to ask for troops. I find it strange, as Chicago doesn't want troops. I also have experience asking him for assistance – just to have the rug pulled up from underneath me when execution meets reality.

Excited to share the first paper from my PhD! We looked at what traits help Aneides salamanders excel at climbing using museum specimens, CT scans, SEM, and more! No claws or toe pads, so how do they do it? In short, with long limbs, big feet and grippy toes! 🦎🧪 DM for PDF doi.org/10.1098/rspb...

Ever wonder how the axial locomotor system is arranged into segmented myomeres of red and white muscle in a large pelagic surgeonfish? Well, now you know! 🐟🧪🦑

I’m proud to announce my first first-author paper of my Ph.D! We described and modeled the muscle architecture of a pangolin’s tongue using DiceCT and 3D modeling approaches. Each model is available on the Holliday lab Sketchfab. academic.oup.com/icb/advance-... sketchfab.com/holliday/col...

Naso! Great genus of surgeonfishes, sporting the vicious cutting scalpel blades at the base of their tail. Here is a better color photo of that bignose where you can see the tail blades. 🐟🦑🧪🌎

Bignose Unicornfish! Yep, Naso vlamingii, a very nice specimen for our research, collected with permit. They have 2 wicked sharp scalpel blades on each side of their tail base, but are they venomous? We will know soon! 🐟🦑🌿🧪🌎

Acanthuriform fishes! Research goals on Moorea are focused on morphology and evolution of defensive spines and backbones of surgeonfishes, angelfishes, and butterflyfishes. We have a scientific permit to collect specimens, and here are 2 beauties, Acanthurus lineatus and Pygoplites diacanthus. 🐟🦑🧪

Local Moorea fish markets are interesting, with stringers hung (and often taxonomically sorted!) on the side of the road. Gotta get there early- these were mostly gone by about 5:30 am. Some good specimens for Linnea and Olivia’s research! 🐟🧪🦑🌎

The Red-Vented Bulbul stopped by my cottage on Moorea. You can just see his red ass! 🧪🌿🐦‍⬛

Shark’s Tooth Peak, the dramatic volcanic backdrop to our research on marine fishes here at the CRIOBE marine lab. 🧪🐟🦑

Doing some work at the CRIOBE marine lab on Moorea with some students. This place is fantastic, the staff are so great, efficient and helpful, and the access to the water is easy and fun. A few posts from Opunohu Bay to come!

Our new REU student Darla found something interesting in one of her CT scans! Looks like this fish was halfway through eating a big snail and some coral rubble when @mwestneat.bsky.social caught it last summer in Okinawa!

Pretty pleased with this mahi (Coryphaena hippurus) in the Keys today. What a great fish! This little one was released but we did get a couple that were keepers for dinner. #CatchAndRelease 🐟

New species of sucker just dropped👍 mapress.com/zt/article/v...
