Bumping to the Fishes! and Science feeds🐟🧪
Finally out! We studied the retinas of the longest-living vertebrate, the Greenland shark, and found that the retinas remain remarkably healthy in animals around 150 years old. What is the mechanism? It may be a highly efficient DNA repair system. Enjoy!

To add: @andrewjohnston.bsky.social wrote a great blog post about his photo stacking system, which you can read here: www.insectid.org/post/focus-s.... It's more expensive, but you get better results! I'll be adding this link to my post, since I forgot earlier.

Great news article about the Tulane University Biodiversity Research Institute's Royal D. Suttkus Fish Collection and our recent accessions of specimens from the DEEPEND Consortium and the University of Louisiana at Monroe.
There are 8 million fish in a World War II bunker outside New Orleans. More arrive soon.

The past few years I've given my students assignments to create Wikipedia pages on various topics. This semester's Fisheries Management students were assigned to write about an ichthyologist/fisheries manager that didn't have a page, with emphasis on women or POC encouraged. I'm sharing them here:

Excited to see this out. Started with RMC students in 2019 and mostly finished in the spring of 2020..... Worked & added over the years, but other projects pulled me away. Submitted it this summer! RMC funds allow for open access so take a look! Photo by M.C.W. Keijman.

2 Fast, 2 Furiosus: The Carolina madtom’s species name “furiosus” is a reference to the sharp sting they can deliver to would-be predators + clumsy fish biologists. These bee-like stings come from the large spines on their pectoral fins that deliver a mild (but painful) venom #25DaysofFishmas
