What Kind of Turtle is This??

My aunt just sent me a picture of this turtle they saw at the zoo and I don’t know what the heck it is! I’ve been googling trying to find pictures of similar looking ones and I can’t find anything.

Seems to be a bit deformed. @Markw84

looks like a very old Pseudemys. Could very well be a nelsoni, which are much higher domed. Can't be sure from just this picture, but that would be my best guess and 80% sure - Florida Red-bellied Turtle

Cooter or slider of some sort would be my guess. Weird looking carapace though?
