To test whether animal coloration is disruptive sensu stricto

Indeed, animals can be recognized by the local fragments of their contours (Fründ & Elder, 2013), making chorion feature particularly important for animal recognition. Alternatively, this result might be an artefact of our specific shape treatments and thus may not pertain to more realistic animal shapes. Further work is needed to evaluate whether our results can be replicated with other global shapes, if we are to confirm that shape distortion does not underlie the proximate mechanisms of disruptive camouflage.
