There is evidence that the facial pit and eye are protected by skin and scales during predatory strikes in Bushmasters (Lachesis spp.) and Jumping Vipers (Atropoides spp.). In this study I investigated a possible mechanism for this event based on the presence of a postorbital-maxillary ligament found in these taxa. The formal description of this mechanism and the examination of additional pitviper taxa will be forthcoming. My initial hypothesis is that the postorbital-maxillary ligament may have more than one function in these snakes.
