Big Pond...what I mean't is that turtles in the family Chelydridae are almost totally aquatic, rarely coming to the surface for extended periods...there are exceptions, notably during mating season when you see them in fields and on roads...however, I don't consider that "basking", just looking for love !...Juveniles will occasionally "bask" for periods of time...and I'm sure there is the occasional adult "renegade" that defies the family habits...strangely enough it is recommened that captive speciemens be given the opportunity to bask, particulary as Juveniles...
