The bushmaster (Lachesis muta) is the largest pitviper in the New World tropics and confined to tropical lowland wet forest, ranging from southern Central America to northern South America. It is a pale fawn color with some fairly distinctive black triangular markings. Check out the webpages of Digimorph at UT Austin (under the all too aptly named "Deep Scaly Project") for some sobering craneal models and more information relating to this species.
