Agassiz's Anole (Anolis agassizi)
It is endemic to Malpelo Island, located off the Pacific coast of Colombia.
Large males of this species are characterized by a prominent, permanently erect nuchal crest, as seen in the image.
The species inhabits rocky terrain with minimal vegetation and feeds primarily on insects.
Steppe mar and boreal mare can and do hybridise, and remarkably there offspring are often fertile despite having split off from one another 18 million years ago. More remarkable is that offspring prefer neither the steppe or taiga, but the tundra.
