Résumé / Abstract

The Taiwan colubrid snake Oligodon formosanus feeds almost exclusively upon the eggs of other reptiles. Snakes that specialize on the eggs of birds usually swallow eggs whole then crush them. Oligodon instead uses enlarged, blade-like rear maxillary teeth to make repeated slashes in the leathery egg shell, inserts its head, and swallows the yolk. The mechanics of cutting involve cycles of extreme displacement of the maxillary bone, whose blade-like teeth are swung in arcs to make ever deeper slashes in the shell until a slit is formed. The cycles during cutting involve protraction, engagement, and retraction of the palatomaxillary arch of one side while the contralateral jaws maintain a continuous hold on the egg surface
