In one study, wolves detected moose using scent ten times, vision six times, and once by following tracks in the snow. Their vision is as good as a human's, and they can smell prey at least 2.4 km (1 + 1 ⁄ 2 mi) away. One wolf traveled to a herd 103 km (64 mi) away. A human can detect the smell of a forest fire over the same distance from ...
Persistence predators can hunt prey many times their size. No extant members of Archelosauria are known to be long-distance hunters, though various bird species may employ speedy pursuit predation. Living crocodilians and carnivorous turtles are specialized ambush predators and rarely if ever chase prey over great distances.
Being an all-white moose in a dark green forest really makes it stand out, making it easy prey for a hunting predator. I hope this one has good luck in avoiding becoming a meal. Looking for more ...
One potential method by which fish schools or bird flocks may thwart predators is the ‘predator confusion effect’ proposed and demonstrated by Milinski and Heller (1978). [9] This theory is based on the idea that it becomes difficult for predators to pick out individual prey from groups because the many moving targets create a sensory ...

Prey naïveté hypothesis is a theory that suggests that native prey often struggle to recognize or avoid an introduced predator because they lack a coevolutionary history with it. Prey naïveté is believed to intensify the effects of non-native predators, which can contribute significantly to the risks of extinction and endangerment of prey ...
Male Western moose stand anywhere from 1.9 to 2.0 metres (6.2 to 6.6 ft) at the shoulder.
