Just look into his vertically elliptical pupil, and you will know it was meant to be!


Look... He toadally DIGS herpetology!!!!!

On 3-24-11 our class traveled to Francis Marion National Forest to visit the Ion Swamp. This swamp is a series of overgrown rice fields separated by a network of dikes. Here a student found an adult marbled salamander (Ambystoma opacum). This salamander is very easily identified by its black and silvery/white marbled coloration. It is thick bodied and has costal grooves. No nasolabial groove is present like those in the family Plethodontidae. This particular salamander was about five or six inches long and was found in the woods bordering the swamp. Marbled salamander larvae are born in the water and metamorphose into terrestrial adults.
We also found a bunch of green anoles (Anolis carolinensis) all those that were found were adults and appeared to be females due to the lack of a dewlap. The anoles were about four in
ches long and all changed colors from brown to bright green over a few minutes after being caught. Some were caught in the forest bordering the swamp, but I caught a large one in the swamp. They are highly territorial so we made sure to release them very close to where they were found. (Logan Bryan, SC)
Our class took a field trip to Dungannon Heritage Preserve in the ACE Basin on 4-21-11. The habitat we investigated was made up of mostly old rice fields turned to swamp. Here we found a vast amount of southern cricket frogs (Acris gryllus) which varied in morphology greatly. We also found four banded water snakes (Nerodia fasciata) all but one were caught in minnow traps. The fourth was found slightly under a log on the outskirts of a swampy area. We knew they were Nerodia due to their keeled scales and dark, thick bodies. They have rounded pupils and fairly slender heads, so we knew they were not cottonmouths (Agkistrodon piscivorus). Furthermore, their bellies were brightly colored with red and yellow alternating marks and faint yellowish bands were on their sides. Two of the water snakes we found appeared to be adults because they were a few feet long. Both of these had tapering tails posterior to their anus, so we deduced that these were females. One of the smaller ones was very aggressive biting one student in the hand and arm many times. The snake that was found under the log flattened its head to make itself appear like a venomous species.
In the same area we caught two of the water snakes (on a dike next to where an old rice trunk appears to have been) I saw a black snake. I yelled, “snake snake”, in hopes Keith, our snake enthused lab TA would come assist. Eventually, with the help of another student we cornered the snake and Keith caught it. The snake turned out to be a black racer (Coluber constrictor). This snake, like one of the water snakes, was very aggressive biting him on the hand and fingers many times. We determined due to the thickness of the tail that this snake was most likely a male. It was several feet long with a very thin body, and probably an adult. It was all black with a dark grey belly and smooth scales. (Logan Bryan, SC)
We saw one small alligator (~4 ft) while paddling to our camp site but we could not get close enough for a photo. Arriving at the campsite we took some time to set up camp and then went exploring. We found several large sliders, a southern toad, and an eastern spade foot toad, none of which I photographed. After flipping over several logs we came across my favorite salamander species, the marbled salamadner (Ambystoma opacum). This Salamander was identifiable as a member of ambystomatidae because of its robust size, lack of nasolabial grooves, and conspicuous costal grooves. It was identifiable as a marbled salamander by its unique silvery/grey dorsal pattern. The photos aren't the best because of the camera I was using but the salamander is still easily identifable based on the dorsal pattern. These salamdnres are typical of low swampy areas such as eschaw creek but are also found on drier sites. They are sit and wait predators with small home ranges. This one probably spends a lot of time under the log where I found it.
Finally on the way back to civilization we came across a reddish snake crossing a forest road. Stopping to examine the snake more closely it became clear it was a corn snake based on the dark spear mark on the dorsal surface of the head and the checkered pattern on the ventral surface. This scientifc name is Elaphe guttata and it is a member of the family Colubridae. These snakes are common in all types of woodlands. This particular specimen was found in a pine flatwood. These snakes are primarily nocturnal but I've personally encountered them frequently crossing roads during the day, especially during the summer. Perhpas they are searching for mates more actively during this time of the year.
