Amblipigido dentro de la Estructura 42. Complejo arqueológico de Yaxchilán, Chiapas.
This is one of the most incredible beasts I've ever seen. Found it in our cabin on the saltillo tile floor. The coin in the photos is a Mexican 5 peso coin which is slightly larger than a quarter. This fellow escaped under some furniture. I'd rather not step on it at night while barefoot!
Mama with babies. Maybe Heterophrynus elaphus?
