It looks as if this little one is practicing their dance moves — slow-slow-quick-quick — but we’re pretty sure fish can’t dance. It's more likely this bellowfish, or Notopogon sp., is taking advantage of snacks in the sediments, stirred up by the ROV's robotic arm. #uruguaysub200

1/8 Excited to share our new paper in Science Advances! We investigated the evolution of endothermy in ray-finned fishes by integrating phylogenomics, ecomorphology, fossil occurrence, and comparative genomics across 205 marine vertebrates. 👉 science.org/doi/10.1126/sc…

New fish paper! We found that Clinocottus globicpes eats anemones (weird!) using a novel wrestling behavior + strong jaws that likely started as adaptations for tearing algae. It also has thick skin that protects it from stinging cells. doi.org/10.1111/jzo.70…

Out today in @PLOSBiology! We show that two major advances in fish feeding - highly protrusible jaws and large teeth - are functionally and evolutionarily incompatible with each other. @MikeMihalitsis and Peter Wainwright. Free to read: journals.plos.org/plosbiology/ar…

@JamesAl0410008 This picture sent me down a 1 hour rabbit hole on this genus 😂

Parodon species, commonly known as Scrapetooths, are characiform fishes adapted to torrential rivers of the high Andes, where they graze algae from rocky substrates with muticuspid triangular teeth.

3/10 Complex teeth (e.g. molars) are a key innovation for mammals and squamates. In fishes, they evolve many (>86) times but remain rare (~11% of species), evolving slowly across most of the tree. But in a few groups, the rate is significantly increased – evolutionary lability.

Check out this Hemipsilichthys papillatus (MCP 39539), a member of the 'primitive' loricariid subfamily Delturinae from the Paraíba do Sul drainage in southeastern Brazil. It has large cheek odontodes like the more diverse Hypostominae subfamily, but it can't evert them.

@DiverDarien Congrats, Darien! This looks awesome!

Super proud of my 2nd PhD paper exploring shifts in evo. integration among reef fish fins with expansions in locomotor modes, out now in Evolution. Within modes there is much diversity in fin shape and weak connections between form and function. doi.org/10.1093/evolut…
