The turtle pool had a label showing:
[i]Rhinoclemmys funerea
Rhinoclemmys pulcherrima
Trachemys venusta
Trachemys scripta elegans
Trachemys emolli
Kinosternon leucosternum
Kinosternon scorpioides
Chelydra acutirostris[/i]
Not sure if all of these were still present as I was pushed for time and couldn't spend too long checking! There were certainly at least the two [i]Rhinoclemmys[/i] species, at least two of the sliders and [i]Chelydra acutirostris[/i].
