Yucatán Casqueheaded Treefrog

Triprion petasatus
(Cope, 1865)
Yucatán, Mexico. June 27, 2016.

I’ve wanted to see this species ever since reading Dick Bartlett’s account of finding these frogs (In Search of Reptiles and Amphibians). During dry times, this frog finds a crack, crevice, or hole to hide in, and uses its bony head as a door (use of the body as a barrier is termed phragmosis). Fortunately, they come out on the roads when it rains at night. I’ve also found them at night by following their quacking call to small aguadas, which are small pockets and pools of water in the limestone that underlays much of the Yucatán peninsula.
