I was reading online some tree frogs are able to regenerate entire limbs. My Cope's gray tree frog had his finger tip/suction cup severed and I was wondering if this species was able to do so. He was hiding in the top blacked out part of the aquarium and put down one finger when I opened the terrarium... I didn't noticed when closing the door and he jumped tearing off his finger tip. The injury looks good now and he's back to normal. I however still feel terrible about it. Are gray tree frogs able to regenerate?
