These are the pitfall traps, which are the way we obtain most of our animals. Holes are dug along the trap every ten feet. When an animal jumps into the plastic wall, it hops alongside it to find the way around it, but instead falls into a bucket nestled in one of the holes. These traps have helped us this year to catch musk turtles, painted turtles, green frogs, one pickerel frog, one bull frog, and a few snakes too.
Just having taken these down last Thursday was emblematic of the closing of our studies in herpetology. Easier taken down than put up, the permanent closing of the traps marks the end of the season.
Here, Laura, Sam, Bobby, Matt, Nate, Ali, and I are shown at the outset of the herpetology unit putting the finishing touches on the second trap.

Bullfrog
This is a bullfrog. It's scientific name is Rana catesbeiana. In this specific picture, a green frog is riding on the bullfrog's back. All the frogs in the picture were captured in our pitfall traps. This was our first and only bullfrog caught during our time in Herpetology. Like all the other frogs, we measured its nose-to-tail and tibial measurements.

Pickerel Frog
This is a pickerel frog that we caught in the pitfall traps. Pickerel frogs can be identified by their spots and yellow stripes down their back. They are generally smaller than green frogs and bull frogs.

Painted Turtle
This is a painted turtle. They are easily identified by their black skin with yellow stripes on their head and red stripes everywhere else. They also have a black shell with an orange stomach. They have a complete plastron which allows them to completely hide inside their shell. We often find them around the ponds or swimming in the Assabet river behind the school.

Green Frog
Frog in a net
This is a frog we captured in a net instead of our traps. We saw him near the edge of the water so we grabbed a net and went on the hunt. Matt touched the water behind him while I put the net in front of him and he jumped right in.
Nate Otenti - Musk Turtle
This is a musk turtle. It was found in a trap behind Hudson High School. The musk turtle is easily identified by its raised shell and distinct, foul, smell. Like all of our other captured turtles we conducted measurements on the musk turtle to determine size, mass, and distinct markings.
In the picture above, the musk turtle is being measured with calipers. We measure the depth, width, and length of all of the turtles we capture.
