Abstract
The Yucatan neotropical rattlesnake (Crotalus tzabcan) is a crotalid endemic to the Yucatan Peninsula. Although it is widely distributed in this region, it is considered a highly elusive species, thus knowledge about its natural history is scarce, including observations on feeding ecology. Here, we report the first documented observation of a predation event of a wild C. tzabcan on a rat in a rural area in southern Quintana Roo, Mexico.
