Description: Yucatan casque-headed tree frog (Tiprion petasatus) Uxmal, Yucatan, Mexico I foun this frog at around 6:00 pm. It was already dark. It was located in the wall, outside of its little hiding spot, right next to a banana tree. It's the first time I've ever seen one of this in real life, but I did know they usually hang around banana trees :). Date: 29 November 2009, 07:17. Source: Triprion petasatus.
