A amazingly well camouphlaged lizard. Coulouring and ridges allow it to disappear in the leaf litter... browns, greys and disruptive lines make it almost impossible to spot unless it is moving. Including tail this specimen was a little over a foot long (11" ... 27cm).
Rainforest/terra firme leaf litter in Peruvian Amazon. This one was in the Allpahuayo-Mishana National Reserver, about 23 miles southwest of Iquitos, Loreto, Peru. Also found in Brazil.
