Do So-Called Aquatic Turtles Bask?
Yeah, they do. Even stinkpots, long regarded as almost completely aquatic, bask in nature (I often photograph basking wild stinkpots). I have photographed many basking spiny softshells and a number of common snappers. With very rare exceptions (a.k.a. adult alligator snappers & Fly River Turtles), you should assume a turtle basks at least rarely. Individuals vary (my pet stinkpot almost never basks; a friends basks a lot).
