Sturgeon and Paddlefish are sadly under threat. These beautiful animals, which survived the KT extinction, are a part of our shared natural heritage as a species. A very old and irreplaceable part of the history of life that is at threat.

Summer courses at Friday Harbor Labs have launched many scientific careers. Including mine. I was more reluctant to leave at the end of the course than other students.

I promise you will have fun and learn more than you can imagine.

Coelacanths illuminate deep-time evolution of cranial musculature in jawed vertebrates Revised coelacanth cranial muscle anatomy reveals previously unknown evolutionary innovations and redefines gnathostome muscle evolution.

A #ScienceAdvances study has found that the coelacanth—an evolutionarily ancient fish often nicknamed a living fossil—lacks 11 jaw muscles that researchers previously thought it had. https://scim.ag/4shX82H

All of the fish species featured during the 2025 #25DaysofFishmas

That's a wrap on 2025's #25DaysofFishmas - the 10th year of #Fishmas silliness! Thanks to everyone who has followed along as we explored some of the amazing fish that call the US home.

From Atlantic to Pacific, there's a lot worth protecting - wishing everyone peace and renewal of hope for 2026.

NEW pub in @science.org 🥳

Is it sponges (panels A & B) or comb jellies (C & D) that root the animal tree of life?

For over 15 years, #phylogenomic studies have been divided.

We provide new evidence suggesting that...

Eastern winds powered an upwelling lake event -this is when eastern winds push the warmer surface water layer exposing deeper, cooler waters. The water temperarure in Lake Michigan went from 25.22 °C (77.4F) on 07/24, to 18.63 (65.5F) on 07/31, and then as cool as 13.72°C (56.7F) on 08/03!!!
