Green Frogs About To Take The Plunge

11-9-15 A. bullfrog 005Most Green Frogs have disappeared over the last few weeks, but this male (eardrum, or tympanum, is larger than his eye) was basking in the last bit of sunshine he will see or feel for the next five or six months. Soon he will take the plunge and bury himself in leaf litter at the bottom of the pond or lay, partially exposed, on the mud beneath the leaves. (Green frogs typically hibernate in water, but occasionally overwinter on unfrozen stream beds or seeps, as well as underground.) Aquatic turtles can shut down their metabolism to a greater extent than frogs, so they are able to survive hibernation buried in mud, where there is little oxygen, but frogs overwintering in a pond must have their skin at least partially in contact with oxygen-rich water. Green frog tadpoles will typically, but not always, overwinter prior to metamorphosing the following spring.
