Group living has the advantages of there are more eyes to be on lookout at any particular time, that the predator must deal with the confusion of a stampede in the middle of a hunt, and that the probability of being selected for capture by the predator is less because of all the other individuals in the herd. Escape in Space Escape in space is the most common strategy used by prey. They will simply out run or out dodge the predator. It is not necessary for the prey to be ultra fast, only faster than the predator. Most predators that are faster then their prey, cannot sustain that speed for very long.
Eyes frequently give away the location of a prey.
So they are disguised. For Batesian mimicry to be effective, though, the mimic must generally remain a great deal less abundant than the model. This allows for a lower frequency of encounters between predators and edible mimics, and a higher frequency of encounters between predators and inedible models. Hence, predators will learn to associate those colors with bad taste. This involves an unpallatable mimic and an unpallatable model.
