No better reason to join Bluesky then to say the first chapter of my PhD is out as a preprint! New surgeonfish phylogeny, ecomorphological relationships, evolutionary shape correlations-with NEW method to accurately account for phylogenetic covariation among shapes!

Happy to share our new paper in Nat. Comm. on the evolution of planktivory in surgeonfishes and relatives 🐠🧬
Combining fossils and genomics, we find multiple independent origins of planktivory, plus convergent positive selection in key genes linked to planktivory.

Newly discovered feeding kinematics may be a key innovation that allows surgeonfishes to efficiently feed on algae across the world's coral reefs. Great new paper by Mike Mihalitsis in Communications Biology 🧪🦑

Never realized why they are called surgeonfishes. Very cool!
Naso! Great genus of surgeonfishes, sporting the vicious cutting scalpel blades at the base of their tail. Here is a better color photo of that bignose where you can see the tail blades.

Hey Bluesky! Did you know that Caribbean parrotfishes and surgeonfishes eat fish feces, especially that of planktivores? Our research suggests that these feces may be a rich nutrient supplement–a fish "vitamin sea"! 💩

Other surgeonfishes have pelagic larvae, but none are quite as remarkable as juvenile louvars. This unique and beautiful larval stage is called an astrodermus, meaning starry skin, and was originally described as a different species to the adult.

We find that these feeding repertoires are underpinned by 3 main feeding regimes, namely, lateral biting, ventral biting, and brushing. These regimes are functionally linked to the upper jaw tooth morphology of surgeonfishes.

"Monotypic fishes"—species that are the only member of its taxonomic group—is the latest #SundayFishSketch prompt. Here's a louvar, the lone species of Luvaridae. Basically if surgeonfishes and tangs evolved to become giant tuna-molas that cruise the open sea!

And surgeonfishes are also the only known host of the bacteria Epulopscium, which helps them to digest the algae that makes up their diet. As algae grazers, surgeonfishes are extremely important in maintaining the health of coral reefs.
