Broadhead skink

Skidaway Island State Park with Amos and Eva - 05.12.2013 - 10.25.19A broadhead skink Plestiodon laticeps that was a bit too fast for me. This specimen was fairly large, probably approaching the maximum in the normal size range for this species at about 30 cm in total length. I found this specimen at Skidaway.

Diamondback Terrapin

I found a Diamondback terrapin, Malaclemys terrapin, outside of my apartment in May. Well… Amos really found her, but I made the catch and provided the identification.

She was likely gravid and was setting out to lay her eggs outside of the salt marsh adjacent to my apartment. While I prepared my camera, I placed her on the patio with Rocky, my Eastern Box Turtle, who promptly mounted the terrapin…

Eastern Glass Lizard

On my way into Armstrong Atlantic this morning, I found this legless, Eastern Glass Lizard: Ophisaurus ventralis.  It was positioned in the posture in the photographs when I encountered in on the side of the road, so, when I dismounted my bike and approached it, I hesitated to grab it to avoid being bitten… Then, when I did grab it, I realized it was stiff and dead.

Glass lizards resemble snakes, in that they don’t have legs, but have external ear openings (the hole on the head, behind the eye) and movable eyelids.  Relative to snakes, they’ve evolved from a distinct lineage of lizards and belong to the family Anguidae. Anguids look a bit like skinks, especially those  Anguids with legs, and I’ve encountered one in Costa Rica – a beast of a lizard called a galliwasp.  Glass lizards are reportedly pretty common around here, and I’ve seen one other on Skidaway Island, but it was too fast to catch.  A friend also captured some on video mating… (edit: before seeing the video, I thought the subjects were anguids – looks more like broad-headed skink though)

Green anole – Norops biporcatus

This anole suns near the lab at the Las Cruces lab most days, and I was recently able to catch and key it.  This is likely a female; she lacks a prominent dewlap.  Norops biporcatus is a large anole that is most often bright green and resembles Dactyloa spp. and Polychrus spp., because of its size.  However, presence of elongated, unkeeled lamalle on its toes, and dorsal + nuchal ridges help to place it in Norops.  I was really hoping for a Polychrus: the Neotropical chameleon… but it was still fun to catch.

Stream anole

A second species of stream anole, Norops aquaticus, found at Quebrada Cusigno at Las Cruces during a bat-catching trip.  The other, which I’ve seen in RBAMB and Hitoy Cerere, is N. oxylophus.  One cool distinguishing feature: N. aquaticus has greenish eyes, whereas N. oxylophus has coppery eyes.

Dewlap coloration – N. aquaticus has yellow stripes throughout the dewlap.
Greenish eyes!
