Mark your calendars!

🧪🐠 I am hiring a postdoc! Work will be on patterns of biodiversity across phylogenetic scales using teleost fishes as a model. Apply by end of Jan 2026 for full consideration apply.interfolio.com/179070 I encourage folks to reach out with any questions. Please Share!

Oooh, such cool teeth! Hurrah for heterodonty!

Data sciences postdoc fellowship in EEB @ U.Toronto app deadline Jan 23 2026. Opportunity for independent research, encourages collab across labs/disciplines. Lots of great folks to interact with, Come join us! datasciences.utoronto.ca/postdoctoral...

Disabled students belong in biological sciences spaces! Here is a thread of some tips and suggestions to make your spaces more inclusive.

My #comparativeanatomy students did a great job on their UnEssays this semester! We had a music video, children’s book, board games, and several art pieces! A small sampling in this thread - really they were all tremendous!

I'm recruiting a Ph.D. student for Fall 2026. Interested in comparative studies and trait evolution in fishes? Send me an email with a CV and research interests. Please take a look at my website (jcorush.github.io ) for more information about my research. #hybridization #minnows #mudskippers

Live-streaming various marine mammal sounds - this could be perfect for background as I grade!

Cooool!

Saw this beautiful nudibranch at Bird Rock, San Diego. No idea what species and iNaturalist tried to tell me it was an anemone. 🙄 Anyone on #Invertsky have an id for this beauty? 🧪

Doomscroll safety stop 🛑 Seeing this longhorn cowfish at the Birch Aquarium this week brought a smile to my face. Like other boxfishes, they are fins-only swimmers because their scales fuse together, preventing the body from bending. And they look like Zoolander doing blue steel. Ok carry on

One of my all time favorite authors! If you haven’t discovered her work yet, please drop everything and pick up either “The Fifth Season” or “The City We Became” from your local bookstore.

I also found it useful for regular human anatomy class!

Hey, if you’re thinking about comparative anatomy textbooks for the Spring semester, you should check out ours! Free, open access, and peer-reviewed!

Today while shopping, my 12yo casually dropped a 1.5 ft tall light-up plastic dinosaur wearing a Santa hat into our cart, assuming that I would buy it no questions asked. 🦖 They were not wrong. It will go well with the 4 ft octopus holding ornaments that was already in the cart. 🐙

Busted out my reliable brain slug for Halloween 🎃

This is yesterday’s postcard-perfect view from my office in our Center for Research and Teaching Excellence at Allegheny. I love the show that Mother Nature puts on in the autumn!

😮

Happy Mole Day!

I know I’m not the only comparative anatomy prof that has been shipped Mustelus instead of Squalus for lab. Is anyone working on a lab manual or online resource that has head muscles & digestive system images? I can’t - I don’t have the capacity right now.

Being part of the team that has brought our Center for Research and Teaching Excellence to fruition has been an absolute delight! We’ve created a vibrant and welcoming space for our faculty. Also, I got to use the giant scissors!

Things I said at work today: "Where did I put that bag of cats, I just had them earlier this week..." "Sorry about the smell, I've got a lamprey" "Can you please bring these chemicals up to the lab? I want to clear and stain Nemo." "I've got chickens, cow, pig, horse, a goat, and 3 dinosaurs"

Oh. Chocolate plant-based protein shake with a banana and spoon of peanut butter has been my go-to work day breakfast for several years, since dairy has become a no-no for me. Protein helps keep my blood sugar stable, but I still need a carb kickstart with it (banana). 😞

Vought posted on X that RIFs have begun. We have not heard of them impacting CDC, or if this is another bluff to induce more trauma and terror before a long weekend. Nevertheless, some tips to prepare if you get a RIF notice below 👇 www.cnbc.com/2025/10/10/t...

A gentle reminder for whoever needs it: you don't have to make yourself small for anyone. You are perfect, exactly the way you are.

It’s band-tober, which means that marching band is our entire life right now. Tonight was a small show (4 HS bands and 1 college band), but the closer had them all playing Sweet Caroline together. Music brings such joy in a timeline where it is tough to find.

My comparative anatomy students had a blast learning with these @3danatomystudios.com shark skull models this week!

One more cephalopod video for your enjoyment: clumsy Nautilus <donk>

Doomscroll safety stop! 🛑 Watch this wickedly awesome video of a sperm whale eating a giant squid! AND if you read the thread, you’ll see it’s been fact checked. 🤯 Ok, carry on

I need more papers like this in my life

OMG, amazing. Although, if they're having poultry for dinner, they're not wrong about it being dinosaur meat.

Wow, it’s been a while since an afternoon of lab work has made me this stinky. But I did manage to finally prep out a freeze dried snake and a barracuda head . Both have been sitting in my work freezer for 8 years, and before then were in Tom Frazetta’s freezer probably for decades.

JOBS JOBS JOBS! Stony Brook are advertising two assistant professorships in vertebrate palaeo/evolution, one focused on (in the words of the SVP programme) NOT DINOSAURS and the other on evolutionary neurology: apply.interfolio.com/172502 apply.interfolio.com/172517

Can’t wait to bring this to my comparative anatomy class on Friday! I keep telling them that new stuff is discovered about vertebrate bodies constantly - and here’s more proof of that.

Undergraduate and graduate students can get $1500 ($2000 for international students) to visit and study in our museum collections. Contact a curator to discuss plans first to make sure we have what you need (that would be @planet-of-fishes.bsky.social for the Ichthyology Department). Come to LA!

It’s nice to do something fun for a good cause among all of this <gestures at world> Guest bartending at my local bar to raise $ for a local foundation that benefits our school district’s kids while also representing my kids’ marching band. Our lights are 🎵 and our hats are music themed!

If you know anyone interested in starting a Master's project working on ammonoid phylogenetics (or the phylogenetics of a mollusc group spanning the OAE2 event in the Late Cretaceous), then ask them to get in touch with me. The situation is a little tricky, as it would be funded by the remainder…

Me, this morning, in a weird meta moment: updating slides and lecture notes for comparative anatomy, thinking to myself "ugh, I feel weird aligning my lecture stuff so closely to a particular textbook"... ..and then remembering that I wrote the textbook chapter I'm working with.
