One such case is spiders, amongst which aggressive mimicry is quite common in both luring prey and disguising stealthily approaching predators.

Aggressive mimicry is also common amongst spiders, both in luring prey and stealthily approaching predators.

Pachycephalosaurs, like most of the plant-eaters, had eyes on the sides of its head, so it could quickly spot approaching predators.

Both sexes attack approaching predators, dive-bombing them and engaging in distraction displays to draw the predator away from a nest.

Most species of birds are able to detect approaching predators during unihemispheric slow-wave sleep.

Johnson had been following the caribou tracks in the middle of the river, where they walked in order to give them better visibility of approaching predators.

Therefore, the resting ray is well-equipped to detect approaching predators, which may potentially include any large carnivorous fish such as the tiger shark (Galeocerdo cuvier).

Many primates and birds have elaborate alarm calls for warning conspecifics of approaching predators.
