The reptiles of the South American jungle...
Plica sp. 'Racerunner Lizard'. Colours described as 'mint chocolate chip' to blend in with lichens and mosses on tree trunks that they run up and down. They are reported to even sleep clinging vertically onto the tree trunk.
Imantodes cenchoa, 'Blunthead Tree Snake'. With such large eyes and their vertical pupil slits, these snakes reportedly have great vision. Apparently, their eyes make up some 25% of their head! This snake was hanging out of tree when I was canoeing in the backwaters of the Amazon at night. They are found in lower trees in rainforest throughout South & Central America.
