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

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.

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.

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/plosbiolog…

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.

𝐿𝑎𝑚𝑝𝑟𝑜𝑙𝑜𝑔𝑢𝑠 𝑜𝑐𝑒𝑙𝑙𝑎𝑡𝑢𝑠, a shell-dwelling cichlid takes intense care of their offspring, which they raise in empty snail shells. A team at the Max Planck Institute used 3D-printed snail shells to find out what happens inside.

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/qpae1…

Brand new open access paper alert! We are thrilled to introduce our findings on how "Complexity and weak integration promote the diversity of reef fish oral jaws" out now in Communications Biology led by Dr. Mike Burns
