Seeking frog I.D. and question about metamorphasis

[GrifTheGreat]

Just to add somewhat of an example of American Bullfrogs showing color variation in juviniles even. Here is one that is very dark. I took these photos over the summer.

and judging from the color of its neck I would wager it is a female.

Interesting... the coloration on mine looks a lot like that one.

Better update my pronouns, then. How can you tell? What's the rule? Also, is it only the males that talk, or do both sexes do it?

Both males and females produce a call. The male produces a loud mating call that sounds like someone blowing into the mouth of a large glass jug slowly and the female responds with a call of her own to signal the male, but its hard to describe the female's responce call.

Small Tympanum suggests female.

It's a bullfrog and a very nice one at that. I would love to have it lol! I love my bullfrogs. I have a baby that is very dark and as he has grown he has stayed very dark. I hope he keeps the dark color as an adult. I know it's a terrible cellphone picture. But you get the idea. As he has grown he has lost his baby spots now and is a very dark brown, looks black. I really need to get an updated picture of him.
