The Komodo dragon (Varanus komodoensis) has been the subject of much scientific interest, not only because of its fearsome reputation as a predator (it is one of very few large reptiles to take prey as large as itself), but also because of its conservation status as an endangered species and recent discovery of parthenogenic reproduction. Here, in the first detailed functional analysis of the Komodo dragon's remarkable killing and butchering techniques, we demonstrate the presence of mechanical traits that appear to be unique among modern reptiles, but were probably common in extinct species such as carnivorous dinosaurs and sabre toothed cats. Analyses were based on anatomical dissection, in vivo bite force, pull-gauge and observational data, together with newly-developed 3-D computer-modelling techniques.

 

Results indicate that, despite a relatively gracile skull and minimal bite force from the jaw adductors, this process is accomplished through application of postcranially derived actions, and the capability of its internal and external bone structure for load redistribution. Computer modelling studies like this one are providing unprecedented information about form and function in animals.

 

The 'Computational Biomechanics Research Group' would be happy to support students or start-up collaborations on the many topics that are still understudied.
