Animals have the innate ability to escape from predation. Examples for the same are given below. Select the incorrect examplePrey animals have evolved various defences to escape predation.
Colour change in the chameleon is camouflage: it blends with the background and is not easily seen by predators.
Melanism in moths (as in the peppered moth on soot-covered tree trunks) is also camouflage against predatory birds.
The puffer fish swallows water or air and inflates its body to a large, spiny ball that predators find difficult to swallow; this is a defence against predators.
Poison fangs in snakes are mainly a means of capturing and killing prey; they are an offensive adaptation of a predator, not an innate means of escaping from predation.
So the incorrect example is poison fangs in snakes.
Note: the answer key of the source gives the puffer fish option; that is changed here because inflation of the puffer fish is a classic anti-predator defence.
