However, they also possess odd patches that don\u2019t fit within this regime. Just behind their dorsal fin, they have a grey-ish \u201csaddle patch,\u201d as well as the signature white \u201ceye patch\u201d on the side of their heads.<\/p>\n
This is an example of disruptive patterning, which works by breaking up the outline of a figure using a strongly contrasting pattern. It\u2019s the reason why camouflaged<\/a> animals, as well as camouflage gear used by the military, are rarely a single block color. A patchwork of bold, contrasting patterns does a far better job of confusing the eye and concealing shape than a single shade can.<\/p>\n Confused? The patches on orcas are an example of disruptive patterning.<\/p>\n Image credit: Kertu\/Shutterstock.com<\/p>\n Orcas are apex predators \u2013 they didn\u2019t earn the nickname “killer whales” for nothing \u2013 so this camouflage isn\u2019t used to hide from would-be attackers, but to help them stealthily sneak up on their prey, which includes almost anything that moves<\/a>.<\/p>\n Not all orca pigmentation is the same, though. Scientists have documented how populations of orcas found in different parts of the world\u2019s oceans have their own unique patterning, almost like gang insignia or team colors. The variation is so prominent that researchers can use the patch shapes<\/a> to ID pods of killer whales and use them to track their behavior.<\/p>\n![\"A](\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2025\/07\/orca.png\" "\\"A")
