Recently I acquired a 2 year old female redfoot. She seems healthy and her carapace is smooth, however, I've noticed that her plastron scutes are concave, almost like "reverse pyramiding". Here's a pic - note that she is blind in one eye, I was told she was born this way. The other eye is fine and she has no trouble finding her way around. Is this normal for redfoots? I've never seen scutes like this before.
