I found these two skinks perched on trees directly opposite each other on the trail. Seeing so many skinks clambering around on trees took me some getting used to, as most U.S. skinks are found on the ground, generally under leaf litter or larger objects.

This smaller individual was from little Satonda island. Satonda features a lake composed of brackish water left behind when a huge volcano on nearby Sumbawa caused tidal waves to drench Satonda.

My references are weak at distinguishing the various species of Sphenomorphus from location and photos alone, so it's quite possible that I'm misidentifying one or more of these skinks. If you can confirm or deny these identifications, please send me mail.
