This digitally painted piece honors the survivor spirit of the coyote by tracing its lineage from the first cells of life to the animal trotting our landscapes today. Below the horizon, carefully chosen ancestors mark pivotal moments in adaptation, each contributing to the form and survivor we see today. Above the horizon, Coyote stands alert at the center, framed by both Denver’s skyline and a mountain backdrop, symbols of their ability to thrive in cities as well as wilderness. Embedded in the ground are the skulls and bones of carnivores whose lineages ended long ago, emphasizing Coyote’s persistence in contrast.

This digitally painted piece honors coyote by tracing its lineage from the first cells of life to the animal trotting our cities and the wilderness today.

The thread gives descriptions of all the extinct organisms shown in this piece (not to scale)

Whiteboard with anatomy sucks written. But covered with anatomy fucks

I made sure to correct some blasphemy on campus today

Moon jellyfish recover well from high pressure, their nerves and connective tissue are fine after experiencing 300atm pressure, although their muscles may be damaged. Mitchell Ford &co suggest the jellies could propel hybrid robots for deep sea exploration

Here's a weird question:
How do whales sleep without drowning?

These sperm whales are power-napping below the water's surface, hanging like cocoons in the ocean.

But whales evolved from land creatures: they breathe under *voluntary control*. What happens when the conscious mind shuts down?

For non-anatomists: some lizard bones perched on a finger. A big one in the middle looks like it has drips coming off it and is asymmetrical. For anatomists: The pectoral girdle of a lizard on a finger, like a macabre thimble. The interclavicle is broad and arched and looks like it has drips coming off it. It is not symmetrical. The sternum of calcified cartilage forms a band that is bigger on the right side than the left. The scapulocoracoids are reduced but seem to be symmetrical. The clavicles are askew but symmetrical.

My favorite bones are ones that look like they’re melting.

This was, as far as I know, a normal individual. Things just get weird in there when you evolve away your arms.

two? three? years ago i found a baby alligator snapping turtle on the sidewalk by my apartment, toody and i took it to the river nearby, on our way i found a GIANT acorn and i took it home. we named the turtle Acorn and the acorn Baby Alligator Snapping Turtle.

Very happy that our new paper on the odd, looped optic nerves of chameleons is now out! It turns out having highly mobile eyes require some pretty specialized connections! doi.org/10.1038/s415...

One of those Etsy pages that sells decals that say "Your Bones are wet" and a dancing skeleton.

Your BONES 🦴 are WET💧.

Sorry, I know that's a weird thing to tell someone, but it's:
A. True.
B. Important, for reasons.

Your bones are about 30% water by weight & an adult skeleton contains ~3.2 liters of water, a little less than a gallon.

Stolen from the Internet: a paved path goes up some shallow stairs that curve around to the left. Meanwhile, a foot-beaten trail goes to the top of a green hill, with cloudy skies above.

This picture tells a story about who we are as humans:
we're monkeys that want to see the view from the hill, because it might be pretty, surprising, or neat.

We're driven by discovery, novelty, curiosity.

But you'll also notice how uniform the patterning is.

Let's talk about Desire Paths.

salamander phylogeny with representative limb bones and their cross-sections

New PhD preprint! We studied the effects of habitat and multi-stage life cycles on salamander limb bones! Aquatic and terrestrial spp. have divergent morphs + semi-aquatic and multi-phasic spp. do their own thing + decoupled external and internal shape promote diversity. 🧪🦎

Biomechanical simulations of hindlimb function in Alligator provide insights into postural shifts and body size evolution Locomotor simulations in alligators reveal that transitions to erect limb postures facilitate the evolution of larger body sizes.

New paper on crocodylian locomotor evolution led by Masaya Iijima, w/Richard Blob & me!
More erect hindlimb postures help extant gators support their weight (esp. at ankle), & how these mechanics constrained giant Deinosuchus to a slow walk at best!

Taphonomy is the science of what happens between death and discovery.

I'm recruiting a PhD student to join the lab at @gtsciences.bsky.social in Fall 2026! Broad taxonomic and topical freedom under the umbrella of vertebrate joint form and function. Information here: www.manafzadeh.com – please share 🦴🩻

New paper out in Pediatric Research! We found that feeding in infant pigs raised on a ducted, biomimetic nipple more closely resembled the mechanics of breastfeeding, and that differences in nipple design impacted milk acquisition and overall feeding performance 🐷🍼

Our new paper led by recent lab alumni Hannah Shideler and postdoc Elska Kaczmarek is out in ICB @sicbjournals.bsky.social! For the first time ever, we reconstructed the volume of the oral cavity during suckling, and found that nipple design impacts tongue function.

I NEED to tell you the story of Tae Heung “William” Kim.

He's a graduate student at Texas A&M where he's working on a vaccine for Lyme disease.

He's a *legal permanent resident* of the United States.

And he's been in ICE detention for 12 days & counting, transferred Tuesday to South Texas.

Three‑row table linking scales: fish, penguin, ant. Each row shows an individual silhouette, a pair‑level interaction image, and the emergent collective - schooling fish, penguin huddle, and an ant raft.

New review in PRX Life, where we propose a tangibility scale for the physics of social interactions, and highlight a few tangible examples - from dead fish “swimming” to efficient schooling, warm penguin huddles, and dry ant rafts.
