Wood Frog Color Polymorphism
Wood frogs exhibit a range of different colors. Here are two female wood frogs that were found at the same pond. One is brown and the other is red. To my eye, both colors seem to be excellent camouflage in the forests where these frogs live.
Are these color polymorphisms genetically based or induced by the environment? I am not aware of any research that has investigated this, but I would be very curious to know!
