Santa Fe Lava Lizard, Male This male Santa Fe Lava Lizard (Microlophus albemarlensis) has a far darker chest with more orange than the ones we have seen on other islands. Speciation is at work here: new species that cannot breed with each other were formed from a common ancestor as the result of geographic isolation.

What is that on his nose? Santa Fe Island.
