2. Here, we use computational modelling to predict the optimal countershading pattern for anoriented body. We assess how camouﬂage performance declines as orientation varies using acomputational model that incorporates realistic lighting environments.
3. Once an optimal countershading pattern for crypsis has been chosen, we determineseparately how UV protection/irradiation and solar thermal inﬂow ﬂuctuate with orientation.
4. We show that body orientations that could optimally use countershading to enhance crypsisare very similar to those that allow optimal solar heat inﬂow and UV protection.
5. Our ﬁndings suggest that crypsis has been overlooked as a selective pressure on orientationand that new experiments should be designed to tease apart the respective roles of these different selective pressures. We propose potential experiments that could achieve this.
