In order to protect themselves from being eaten, animals resort to camouflage and chemical defense. Animals camouflage by mimicking the appearance of their environment. Animals that have chemical defenses contain chemicals noxious to predators. Which of these is NOT an example of camouflage or chemical defense?

Thorns are a form of defense, but are neither camouflage nor chemical defense. A walking stick insect that looks just like a twig and a harlequin crab that looks just like the sea cucumber it lives on are examples of camouflage. A skunk that has an awful smell and feathers of the pitohui bird in New Guinea that contain a deadly toxin are examples of chemical defense.
