Description

Found around 9PM. The sky was clear and it was probably in the high 50's or low 60's. Found in the the shallow area of a small lake with grasses in the shallow portion, the lark was surrounded by pines and occasionally other trees (mainly oaks). Around the time this juvenile was caught (since it has all the markings of a Bullfrog but it much too small it is likely to be a juvenile) I heard several other Bullfrogs calling. I'm not sure if they would be calling for the purpose of defending territory or for the purpose of mating.

Description from Wikipedia

The American bullfrog (Lithobates catesbeianus), often simply known as the bullfrog in Canada and the United States, is an aquatic frog, a member of the family Ranidae, or “true frogs”.
