Research overview: skull morphometrics and prey-size relationships across felids

Cat skulls vary in robustness and proportion, and this overview surveys how that variation tracks the size of prey a species typically takes. Cats that tackle relatively large prey tend to have more robust skulls, stouter canines, and features that resist the stresses of subduing struggling animals, while small-prey specialists have more gracile crania. Researchers quantify these patterns with geometric morphometrics and biomechanical modelling, relating shape to estimated performance and diet. Why it matters: linking skull shape to prey size lets researchers read ecology from anatomy in living and fossil cats, clarifies why big cats and small cats differ beyond mere scaling, and underpins broader questions about how predator morphology and prey availability shape one another over evolutionary time.
