I make videos about Earth’s Vanishing Biodiversity. This week, I tell the detailed story about the discovery & swift demise of the Steller’s Sea Cow. Hope you’ll watch, enjoy, and will follow along!

Tune in tomorrow, May 23rd, at 7pm EST to hear the story of how the largest sea cows to ever exist were ruthlessly annihilated in a mere 27 years. We will post both on YouTube & right here on X!

Seahorses have an intricate lattice of interconnecting bony plates, arranged delicately and perfectly to give these animals their characteristic movement.

So it begins! Earlier than in past years and so far only the opaque variant. Ambystoma maculatum
Might as well emerge from my twitter hiatus for this. I'm so fortunate to have these fantastic people as co-authors, especially being my first publication 🙌
In a period with a lot of negatives, it feels good to end a week with a paper acceptance. It's been awesome to have had great co-authors: @jcroweriddell, @scaleyhan, @jaimiAgray, & Alison Davis Rabosky to work with on this. 🐍🐍🐍 #diceCT #herpetology

I had to get creative when setting up this #diceCT scan. The #snake will be chasing the #bat all night long in our scanner! #zoology #CtScanning @UMichEEB #oVertTCN #herpetology #mammalogy @NikonMetrology
