Rebecca Bentley is an FSBI funded PhD student at the University of Bristol, working on the evolution of ecomorphology in armoured catfish (an adaptive radiation of over 1,070 species). In this video, she focuses on how jaw shape is linked to diet and other ecological factors, but constrained by phylogenetics. With some phenomenal micro-CT images of these charismatic little catfish, we get a glimpse into the anatomical features Rebecca is examining as part of her PhD.
