Spatial body patterning is
widely observed throughout the phylogenetic tree and is used for a variety of
functions. Body colours in general and camouflaging patterns in particular have
been extensively studied for their role in stealth and crypsis. Particular
interest has focused on the diverse skin patterns surrounding animals’ eyes
(Peri-Ocular Eye Patterning-POEP). These patterns have been suggested to aid in
high brightness conditions, help camouflage an organism’s eyes or ornament and
emphasize bright head colorations. In this work I demonstrate the apparent
widespread use of POEP among various marine and terrestrial organisms (both
vertebrates and invertebrates) and discuss the trait’s abundance, variations,
and possible roles.
