The turtles in this exhibit complex (Turtle exhibit #1 and #2) appears to be new by the time you visited. This was originally a porcupine complex, with one exhibit occupied by capybaras as the porcupines were moved elsewhere. Do you note of any turtle species in these complex (Turtle exhibit #1 and #2)?
There's signs for Red-eared Slider and Bornean River Turtle and that's it, but I suspect that at least a couple more turtle species are present but unsigned.
@snowleopard I do saw both of those turtles and atleast a small number of Sunda box turtles (Cuora amboinensis couro). I had just remember that there were a pair of manouria emys in there as well.
