| Abstract |
|
Sternotherus minor depressus carinatus odoratus Musk turtles, genus Sternotherus, of all taxa preferentially used crevices as resting sites in laboratory pools. Crevice use was greater during the day. Larger, darker crevices that were low enough to touch the carapace were preferred. Positional preferences within crevices were for full coverage of the shell despite the head being exposed, for the low half of crevices, and for axial orientation that maximized contact between the carapace and crevice ceiling. Light but touchable portions of crevices were preferred over dark but untouchable portions, so the possibility of establishing carapacial contact with the ceiling is the definitive attribute of a satisfactory crevice. The behavioural tendency to use the lowest possible crevice may have an anti-predator function, and it is one necessary condition for existence of a selective regime in favour of depressed shells.
