Was it a salamander in the skimmer basket?
Not knowing where you live I cannot say for sure. But, if it looks like a lizard with a wet skin, then it’s a Salamander or a Newt. I’m very surprised it could tolerate the Chlorine. Since he was in your pool, it would be wise to put him in a terrarium with a bowl of fresh, un-chlorinated, water, so he can soak the chlorine out of his skin. Then, after a day or two, turn him loose. No, they do not bite, and even if they did, you would not feel much of anything. Their teeth are very small and their jaw muscles are not that strong.
