Longtail Salamander
Earlier today, our herp class went on a trip to the Quarry at Hueston Woods, which is about ten minutes outside Oxford, OH. What started out as a cold rainy day eventually warmed up, which led us to find a bunch of different species around a river. While searching among the stones and logs off the shore of the river I uncovered this longtail salamander (Eurycea longicauda). When I first lifted the rock he was resting under, I thought it was a southern two lined salamander, since they are about as common as mud around here. However, when I picked him up, I noticed the characteristic spotting pattern and realized it was the longtail. He was about 4 1/2 inches long with a brown/orange base color and black spotting pattern.
The longtail salamander is typically found along streams, where they tend to hide among rocks and logs. They are identified by their long tails and characteristic spotting pattern. They lay their eggs amongst rocks and around caves, and the larvae usually take about 1 year to fully metamorphose.

Queen Snake at Miami University
Just an hour ago, we were searching for herps at a Quarry in Hueston Woods which is about 10 minutes from Miami University. It turned out to be a good hunt as we found 9 different species of herps. About halfway into the trip and a few hundred yards of searching down a stream, a queen snake, Regina Septemvittata, was uncovered. It was hiding in its typical hiding space of bedrock. They are brown aquatic snakes with stripes along lower sides of their body and can be often confused with Garter snakes. They have keeled scales and a divided anal plate which can be used to distinguish them from Garter snakes. They hide at river's edge to catch their prey -crayfish. They preferably feed on crayfish which recently shed as their shells will be softer.

Plethodon dorsalis
on April 18th I traveled to Mammoth caves national parks as a residence hall event for the violet city cave tour but we got there a little early, so a group of us decided to follow some trails near the visitor center. After a couple of us curious students turned over some logs near the trail and came across these Plethodon dorsalis or the northern zigzag salamander. These guys are usually about 35 mm long once they are mature. The northern zigzag reproduces terrestrially and females can be observed staying with the eggs through the summer season. This species reaches reproductive maturity after about three years of age.Overall it was exciting to find a species that can not be found in Oxford Ohio.

Green Frog Tadpoles
Last Thursday, April 23, our herp class made a brief stop to Miami University's formal gardens to check our turtle traps. Although the traps proved unsuccessful, we were still able to catch a number of green frog (Rana clamitans) tadpoles such as this one. The weather was fairly warm, about 70 degrees, and slightly breezy. The tadpoles were hidden among the leaf litter in one of the small ponds, and were fairly easy to catch. This was not very surprising since green frogs tend to hang around shores of ponds, and since they breed in April, there were plenty of these tadpoles in a fairly small area. As tadpoles, they tend to feed on a variety of organic debris, including algae, and this particular pond was abundant in leaves/decaying organic matter. The tadpoles can take a fairly long time to mature, and some even overwinter and metamorphose the following year. Once they become mature their diet drastically changes and they primarily become carnivores, consuming almost anything they can fit into their mouth.

Common Snapping Turtle
On April 23, out class went to Bachelor Pond to check out our turtle traps. The weather was gorgeous. It was about 65-75 degrees F and there were lots of painted turtles basking on the various logs out in the middle of the pond. The pond was covered with a lot of algae and pretty muddy. In the first trap we found a Common Snapping Turtle(Chelydra serpentina). It was small one in comparison to how large they get. They are the largests freshwater turtle in the US and they can reach up to 70lbs. They have very powerful jaws with a strong hook like beak on the top part of their mouths. They are known for striking like snakes when in danger and don't usually hide inside their shell like other turtles.There skin is usually grey in color and they have a very distinct reduced plastron and the carpace is darker than the rest of the the turtle. The carpace is also keeled and rough but the keels go away as they mature. The tails of snapping turtles also have rough edges resembling saw tooths. Females can lay up two dozen eggs some distance from the water in sandy areas. They mate from April to November. Females are capable of storing sperm for many different breeding seasons and use it as necessary.

Eastern Racer
On a recent trip to the Meeman Biological Station, this Easter Racer (Coluber constrictor) was found entwined inside of an overturned metal boat, much to the excitement of the fellas who do a lot of research out there. (Apparantly the boat had been overturned many a time before, fruitlessly.) Although they are pretty common, I had never seen one of these before. He was simple yet very elegant. His tongue seemed to slither from his mouth in slow, decided motion. These snakes are known to be very fast and very active. Adults typically feed on frogs, rodents, and lizards. Unfortunately, one student was "musked" while handling this fella (or she-lla?) They have been known to bite, however, they are not poisenous. (Stacey McNiell, TN)
Likes long walks on the beach
Undaunted by my presence, This staunch Anaxyrus woodhousii, or Woodhouse's toad, had his priorities straight. I was lured from my house by his love song. This toad was perched on a romantic cinder block bordering the man made pond in my front yard. He agreed to pose for a few pictures, before wandering off, in search of ladies. (Apparantly, I was not the female he was looking for.) This guy likes to burrow and hide when he is not active. Hopefully his night went well, and I will be able to watch tadpoles grow in my pond!

Yard dweller
This snake seriously does not enjoy being handled, leaving me covered in noxious stink juice every time I pick her up, but it was a cool surprise to find her in my own back yard. This common Tennessee snake is currently residing in a terrarium over my (retired) fireplace, and enjoys eating worms, but doesn't seem to care for slugs so much. Her name is Beaker.

This is a Green Frog also known as Lithobates clamitans. The frog was found about ten minutes after finding a Fowler's toad. My best friend has a small pond behind his house and we heard some frog calls. I made him run inside and get a flashlight. We quickly ran down to the pond and found this guy. I picked him up and identified him first. Then we set him near the edge of the pond and we snapped this picture right before he jumped in the water. Lithobates clamitans are usually found in permanent bodies of water such as the pond this guy was found in. They are medium size frogs and their voice calls sound like a banjo string being plucked.

This is the Fowler's toad. My best friend and I found this fat guy sitting right outside his barn. We had just finished celebrating my best friends 22 birthday when I thought it would be fun to go look for some herps. Within two minutes we spotted this guy! The Anaxyrus fowleri has very distinct parotid glands similar to the Anaxyrus americanus but instead the fowleri's parotid glands come in contact with the cranial crest. The fowleri also has 3 or more warts inside dark spots on back. The habitat for these guys is very broad. We found this one right outside my friends barn.

Fowler's Toad
This little guy was in my backyard. This is anaxyrus fowleri. It took me a little while to id him with the help of my professor and TA. These guys hardly like to show themselves to us, especially during the day. I believe why they were out was because we were sucking the water off of the pool cover to get ready to take it off, so the toads were out trying to get some easy pickings. It was a nice sunny day with few clouds. The wind was a gently northerly wind so it was not too hot for this toad to be out. There was another one around but I couldn't find it. I tried picking this toad up and he puffed up. I thought that was so neat when he did that and I got more pics of him like that. He was a little camera shy but I got some good pics.

Eggs!
On April 2nd, 2009, our herpetology class drove to Indian Creek Park in Reily, Ohio. It was around 70 degrees Fahrenheit, with a few clouds and a nice breeze. These eggs were found in a small stream off of the main creek (that wound its way into the woods) and contained a few inches of water, and lots of leaf litter. This small offshoot contained many limestones of various sizes, many of which had salamander eggs attached to the underside.
We concluded that these eggs belonged to the streamside salamander, Ambystoma barbouri. The first reason was that we found an adult underneath of a medium sized limestone just a few feet away from where this picture was taken (see a previous post). The second reason was based on how this species lays its eggs-- individually attached to the underside of rocks (which are usually limestone).
Courtship and mating both occur underwater underneath limestone rocks during the early spring and late winter. A gravid femal can lay upwards of 260 eggs. Eggs are laid individually, and are attached beneath the rocks in the water for two to three weeks, until they hatch. The larvae will then spend anywhere from six to ten weeks there before they metamorphose. The terrestrial individuals migrate away from the breeding site and into nearby forests.
It would be interesting to go back to that site now-- there are probably many tiny streamside salamanders with external gills!

Herpetological Cartoons
Hello Herpers in SC & TN:
Our class has made some herp cartoons. There's really very few people who will have the required knowledge to really appreciate these, so we're targeting our audience. Some are even funny. Just remember as you become scientists--cartoons are funny and flow charts are not cartoons. Also posting a recent picture of the "funny" Ohio herpers.

Another weekend Herping trip
Further upstream in a more stagnant offshoot with a small waterfall and much more tree cover I spotted two snakes sitting in the branches of a small tree overhaning the water. From their patterning I guessed them both to be Norther water snakes (Nerodia sipedon). I was able to coax them out of the tree and into my net seperatly, and I was guessing one to be male and the other female. They were pretty aggressive once I got them in the net, and I wasn't able to pick them up for fear of being viscously bitten, but I still got a few good pictures. These snakes are usually 24-42 inches (so the ones I found were very average size) and prefer quiet waters near swift flowing streams, which was exactly where I found them.
Male
FemaleAlso a species to note that we observed earlier that day around 1:00, still in Oxford but along the wide 4 mile creek (more north east of where we these animals were found) was a Spiny soft shell turtle (Apalone spinifera). We caught a glance of him basking on a wide log that protruded into the middle of the stream. It was pretty far away, so idenifying him by the traditional nostral ridges, streaked foot pattern, or rough shell was impossible. Due to our location, it is more probable to find the Spiny softshell rather than the Smooth softshell. These animals are highly aquatic and prefer large bodies of water where they can bask on logs or hide in mud flatts.

Fowler's Toad
Here we found a couple fowler's toads, Anaxyrus fowleri, in amplexus. We were able to identify them by their skin, these toads have 3 or more warts per spot. Also their cranial crests come into contact with their paratoid glands, which are both characters that differ from the American Toad. We were also able to sex the individuals, the female obviously is on the bottom, but she is also much bigger than the male. The male has a dark chin, as you can see in the picture, while the females venter is all light colored. During the breeding season, which is the warmer months, April-July, the males migrate to shallow ponds or other water bodies and call to attract females. These toads are known to burrow during the day and come out at night to eat insects and other small invertebrates. A couple ways they defend themselves are by having amazing camaflouge, gland secretions that irritate the predator when the toad is in their mouth which usually causes them to be spit out and they have also been reported to roll over and play dead. They are pretty common, I have seen them all my life, so it is not too exciting now when I see them. However, the other night it was really warm and rainy and I could hear males calling in the distance and I found about 15 females in my driveway all heading towards the calling males, which was pretty interesting. Also it is fun now to determine if they are fowler's toads or american toads.

Ambystoma barbouri-- streamside salamander
On April 2nd, 2009, our herpetology class drove to Indian Creek Park in Reily, Ohio. This particular afternoon, it was around 70 degrees Fahrenheit, with a few scattered clouds and a mild breeze. This specimen was found in a small stream off of the main creek (that wound its way into the woods) that contained approximately three inches of water. This small offshoot contained many limestones of various sizes, many of which had salamander eggs attached to the underside. The class lifted up a medium sized limestone and found this guy sitting there. Reaching about six inches, this individual is a very large streamside salamander.
This species is mostly located around the Ohio tri-state area (southwestern Ohio, northern Kentucky, and southeastern Indiana), however, colonies have been reported in western West Virginia and Tenessee. The streamside salamander breeds in smaller limestone creeks located in forests in late winter and early spring. Eggs are laid and attached to the botton of rocks and take between two and three weeks to hatch. The larve take between six and ten weeks to complete metamorphosis. Adult Ambystoma barbouri migrate away from their breeding sites and take up residency in nearby forests under rocks and logs. As adults, they can reach up to six inches in size, and are quite chunky. They have a gray lichen-like pattern on their sides and a small head. These guys can be confused with small-mouthed salamanders (Ambystoma texanum), however their location (stream) distinguishes them.
