On the rocks

Talk about blending in...  

This American Bullfrog (Rana catesbeiana) can change color depending on his environment. Here, he is perfectly camouflaged amid the dark and shiny rocks in the stream where he makes his home.

Soaking up the warm September sun helps this aquatic frog stay healthy and active. As winter approaches he will hibernate in mud, but not bury himself completely, and may slowly swim around from time to time during thaws.
