In this video I discuss the challenges of converting the ray-finned fish phylogeny into a taxonomy. I am quite critical of recent Linnaean rank efforts that create confusion and instability

Here are just a few of the many fish I painted this year (not to scale). It's fun to stick a bunch of them together into a collage and see some of the incredible diversity of body shape and color patterns. Merry Fishmas!

New paper out now! We show that innovations can have varied effects on a phenotypic evolution, determined by the interaction between external ecological context and internal changes to organismal structure. Read here: royalsocietypublishing.org/rspb/article...
Multifaceted impacts of an innovation on dental diversity in an adaptive radiation of cichlid fishes
Abstract. Evolutionary innovations bring species into new ecological zones by opening ecological opportunity. However, innovations can have varied effects

New paper! Here we look at shape evolution of the mandible in Pelagiaria, a group of open-ocean fishes that includes tuna and mackerel. We find that shape disparity accumulated rapidly at the origin of the clade at around the K/Pg boundary... academic.oup.com/evlett/advan...
Adaptive radiation of pelagiarian fishes at the K/Pg boundary led to rapid diversification of mandible morphology
Abstract. Mandibles represent a key evolutionary innovation that has enabled jawed vertebrates to adapt and diversify in response to a range of food source
