The Bullfrog

This is our bullfrog! Note the lack of lateral lines on its back.
On Wednesday we caught our very first bullfrog! Before this, we had really only been finding green frogs with regularity. We were able to catch it in a net, which was another first. We had not managed to catch any frogs in the nets before. Bullfrogs are easily distinguishable from green frogs due to a couple differences in coloring and characteristics. Easiest to see is the lack of black, lateral lines on the back of the frog, as can be seen in the image above. Instead, the back of the frog is a solid green. The bullfrog also has large webbing in its back feet, unlike the green frog.

This is the webbed foot of a bullfrog!
Bullfrogs also tend to be a bit larger in size than most green frogs. The head-to-tail size of the bullfrog we caught was 8.8 cm and the tibia size was 3.9 cm. The weight of the frog was 83.8 g. 

This is us measuring the head-to-tail length of the bullfrog.
Afterward, we had a little fun with the frog. We laid it down on its back and rubbed its belly, putting the frog to "sleep." 

We put the frog to "sleep."
I hope that we are able to find more bullfrogs in the future!
