Need help identifying a frog

[UncleChester]

I've been raising them as a science project for my preschoolers but my husband is hoping to keep them as pets after.

If these are peepers (and they do look like it from the photo) you should know the males have a very loud call. Very, very loud. Be sure you're ready for it before making a long term commitment.

I read somewhere that the way to tell if its a spring peeper is that they have an X pattern on their back.

I don't know its its true but yours does look like this.

It's true they do have an "X" on the back. This is where the "crucifer" part of their latin name "Pseudacris crucifer" come from.

Here's a pic of a freshly morphed one from a couple of years ago (the tail wasn't fully absorbed yet). The "X" is only partly visible in the picture though.
