Pycnodontiform lower jaws and body shape separate from ecologically similar fish clades in a morphospace analysis suggesting minimal competition between these groups. Pycnodontiform diversity appears to be little affected by abiotic factors such as sea level and climate but reef loss may be a more significant factor playing into the success of this ...
