Enophrys taurina CT scan.

Enophrys taurina CT scan

Just wrapped up a week of SlicerMorph/MorphoDepot/MorphoCloud work with @jaimiagray.bsky.social, @cmdonatelli.bsky.social and a great team of folks.

This is Enophrys taurina with a damaged preopercular spine. Fighting or defense?

New from #JRSocInterface: Something to sink your teeth into: the mechanics of tooth indentation in frugivorous fishes: royalsocietypublishing.org/doi/10.1098/... #biomechanics @karlycohen.bsky.social @cmdonatelli.bsky.social @sbcrofts.bsky.social

Four panel figure. A lateral CT scan of a frugivorous fish CT scan with an inset showing the jaws in frontal view. A 3D printed model of the upper and lower teeth opposing each other. The 3D printed models mounted in a materials testing system to allow food to be bitten. The load displacement curve that results from biting fruit in with the model jows.

Jack Rosen's paper on biting fruits and seeds is out in @royalsocietypublishing.org Interface. 3D models of pacu and piranha jaws cutting different prey. Pacus are 'better' at fruit. Maybe eating seeds drove the evolution of frugivory from piscivory.

A photo of a Spotted Gar (fish) underwater with inset photo of gar eggs, which are toxic to mammals, birds, reptiles, amphibians, and most arthropods. There are also hearts in the upper left to make this photo romantic.

Roses are red,
Violets are blue,

These eggs are toxic,
No cavigar for you!

Only 5 days left to submit an application to this summer's #REU - BLINKS program! We're excited to have so many awesome projects lined up 🎉
🦊🦀🪸🐠🌕🌱♻️🌏🌊🤖🐚☁️

Please pass this along and check out our website for project descriptions and application info: fhl.uw.edu/research/sum... @fishguy.bsky.social

We are excited about this summer's #REU - BLINKS program! Applications will close in mid-February. Please share with any students who you think might be interested. fhl.uw.edu/research/sum...

Our REU summer program just went live. Here is the application form...

There is a short time line on this. Please pass it to any interested undergrads.

Myself and 2 collaborators in front of our poster on frog jumping at the SICB meeting

Lorenzo in front of his poster on why tiny fish have so much armor at the SICB meeting

More #sicb2025 posters today!! 6 down 2 to go! Fishes and frogs!

A walrus penis bone sitting on a messy desk.

Here is an odd bit of #DeskDetritus. An unpaired bone from a walrus. The Os Baculum, or penis bone is called an oosik.

Happening now! Form, function, and mechanics of composites! @schulzscience.bsky.social

#SICB2025 #SICBbioinspired @sicbjournals.bsky.social

Now Astrid Layton gets students working on bioinspired design in engineering spaces.

#SICB2025 #SICBbioinspired @sicbjournals.bsky.social

Talk number 2 is up at 2:00pm in Marquis C. If you love knitting or elephants you should stop by! #SICB2025

Many thanks to @cmdonatelli.bsky.social and @karlycohen.bsky.social for organizing such a great symposium on bioinspiration and having complimentary sessions that welcome my weird little urchin camera

Thanks to everyone who participated in our #SICBioinspired symposium today! @karlycohen.bsky.social and I had so much fun hearing from all of you. Thanks also to @biologists.bsky.social and @anatomyorg.bsky.social and @sicbjournals.bsky.social for supporting everyone here today! #SICB2025

If you are looking for armor diversity this is the talk to be at! @karlycohen.bsky.social is now showing is armor shape and material diversity in armadillos. #SICBioinspired #SICB2025

Poacher fishes are able to repair damaged armor! @karlycohen.bsky.social is figuring how and why some repair better and faster than others. #SICBioinspired #SICB2025

Bringing in the whole team to figure out what armor is. @fishguy.bsky.social @schulzscience.bsky.social @karlycohen.bsky.social and Misty Paig-Tran who isn't here in BlueSky?

@karlycohen.bsky.social is concluding our #SICBioinspired symposium with a talk about all things armor! #SICB2025

Next we have @schulzscience.bsky.social starting at 2 PM in Marquis C!

If you are looking at the paper program this is a schedule change you don't want to miss!

#SICB2025 #SICBioinspired @sicbjournals.bsky.social

We are starting back up again strong with Brian Woronowicz talking about tail movement and function in rats

We are back for our afternoon session! Come join us this afternoon in Marquis C for some more awesome #SICBioinspired talks! #SICB2025

Up now is Jessica Tingle using conceptual frameworks for jump between biology and engineering! #SICB #SICBinspired @sicbjournals.bsky.social

Jessica presents us a framework to help find the colleagues to answer your questions! Aiding conversations across the fields of biology and engineering

How we ask think about our questions has major impacts on the kinds of data we collect and share

Armadillo taper affects are not stiffness, making the whole thing bendy but not too bendy

Sebastian Kruppert talks to us about the importance of soft robotics and how do we make soft materials move #SICB2025 #SICBinspired @sicbjournals.bsky.social
