79% will leave behind no science staff.
Screen cap from the beginning of a paywalled Detroit News article titled “Federal Layoffs would gut Great Lakes fisheries research center.” Posted in Oct 20, 2025 at 9:25pm and written by Melissa Nann Burke. It reads “Washington - the U. S. Geological Survey is planning to lay off 79% of the workforce of the Great Lakes Science Center that’s headquartered in Ann Arbor as part of a reduction in force across the U.S Department of the Interior, officials say.”

Colleagues in ocean science academia: 🧪🦑🌎

I am working on the section of my marine biology career advice book about applying to graduate school. I have lots to say here from both my own experience and years of teaching this stuff, but I’d welcome your input on any or all of this if you’re willing.

NSF GRFP is out 2.5 months late w/key changes

1. 2nd year graduate students not eligible.

2. "alignment with Administration priorities"

3. Unlike prior years, they DO NOT specify the expected number of awards... that is a BIG problem.

New paper is officially out!
Ratfish have a second jaw on their foreheads - CT + histology show they’re real teeth, built from the same tissues and signals as oral teeth.

www.washington.edu/news/2025/09...
This common fish has an uncommon feature: forehead teeth, used for mating
New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads,...

Babe, wake up - Xanthochromic nurse shark just dropped..

Caught by some sport fishermen out near Costa Rica (and released after some photos were snapped)

Look at this beaut, how ORANGE!!
A photo of a man in a cap holding the line on which is a very bright orange Nurse Shark ( a very flat, bottom feeding shark that is no threat to humans) in this photo you can clearly see the silver/white eye of the animal.
