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. 👉

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. https://t.co/YUqCjSBWYq

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:

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.

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. https://t.co/aubyF28RXj

The final version of our paper is out: Phylogenomic and anatomical evidence for the Late Cretaceous diversification of African characiform fishes, including a new family, under the influence of the Trans-Saharan Seaway: https://t.co/7nLSiCQcqh

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 https://t.co/WmqxRllzW4

Cetopsis candiru, is a smaller more specialized cousin to C. coecutians. This species has two sets of articulated spurs on its head used to burrow into its victims alive or dead. They can perforate flesh and propel themselves inwards to the softer innards of fish or unlucky

I’ve never been so jealous… I need this!

Hey folks, my PhD advisor, Dean Adams, EEB Dept at Iowa State, is recruiting a PhD student in morphometrics and macroevolution. Lab link: https://t.co/x6TiI9Q99v Email dcadams@iastate.edu for inquiries. I'm also happy to answer questions about the lab, department, and school!

🚨Incredibly excited to share my new pub in collab w/ @cmart_fishmorph, @damalichthys, + @PeterWainwrig15 in @EvolLetters! Opposite of long-held predictions, we find that a pharyngeal jaw novelty restricts diversification of feeding motions + morphology! https://t.co/24OVUaXa8D
