badkelpie: You're welcome. I'm glad I could help.

pez: I checked out the link. Although it has some really good information, it doesn't seem to show how long the total lifespan is for most of these frogs, it shows how long certain individuals survived in captivity. The first entry it has for an American green tree frog lists it as surviving 6 yrs. after being collected from the wild as an adult, so the total age of the animal is unknown. Still a good link though.
