2022 Alaska Groundfish Seminar Series -- Thaddaeus Buser
Stags of the sea? On the evolution and function of cranial weapons in sculpins
About
Many North Pacific fishes are armed with scutes, spines, and barbs. Presumably they defend against predation, but for most species this defensive function is entirely speculative. I used a variety of techniques, including CT scans and 3D motion capture to describe the morphology and use of preopercularspines in sculpins and compared the evolutionary drivers of the weaponizationof sculpin skulls with better-understood terrestrial models, such as the evolution of antlers in stag deer.
