Scientists have improved their ability to model ecosystems by incorporating more information about predator/prey.
This has led to a correlation between the size of predators and their prey. Size may also act as a refuge for large prey. For example, adult elephants are relatively safe from predation by lions, but juveniles are vulnerable. Members of the cat family such as the snow leopard treeless highlandstiger grassy plains, reed swampsocelot forestfishing cat waterside thicketsand lion open plains are camouflaged with coloration and disruptive patterns suiting their habitats.
Female Photuris firefliesfor example, copy the light signals of other species, thereby attracting male fireflies, which they capture and eat. Venom and Evolution of snake venom Many smaller predators such as the box jellyfish use venom to subdue their prey,  and venom can also aid in digestion as is the case for rattlesnakes and some spiders. These changes are explained by the fact that its prey does not need to be subdued. Antipredator adaptation To counter predation, prey have a great variety of defences.
They can try to avoid detection.

- 1. Introduction
They can detect predators and warn others of their presence. If detected, they can try to avoid being the target of an attack, for example, by signalling that a chase would be unprofitable or by forming groups. If they become a target, they can try to fend off the attack with defences such as armour, quills, unpalatability or mobbing; and they can escape an attack in progress by startling the predator, shedding body parts such as tails, or simply fleeing.
They can also adopt behaviour that avoids predators by, for example, avoiding the times and places where predators forage. Camouflage and Mimicry Dead leaf mantis 's camouflage makes it less visible to both predators and prey. Syrphid hoverfly misdirects predators by mimicking a waspbut has no sting. Prey animals make use of a variety of mechanisms including camouflage and mimicry to misdirect the visual sensory mechanisms of predators, enabling the prey to remain unrecognized for long enough to give it an opportunity to escape.
Camouflage delays recognition through coloration, shape, and pattern. In mimicry, an organism has a similar appearance to another species, as in the drone flywhich resembles a bee yet has no sting.
It is lowest for those such as woodpeckers that excavate their own nests and progressively higher for those on the ground, in canopies and in shrubs. Birds also choose appropriate habitat e.
Similarly, some mammals raise their young in dens. However, there are exceptions: For example, Belding's ground squirrel can distinguish several aerial and ground predators from each other and from harmless species. Prey also distinguish between the calls of predators and non-predators. Some species can even distinguish between dangerous and harmless predators of the same species. In the northeastern Pacific Ocean, transient killer whales prey on seals, but the local killer whales only eat fish.
How about the beef, pork, lamb, fish, or chicken you eat each day? Just because you do not kill the animal yourself does not make you less of a predator. You are still an animal eating the flesh of another animal to satisfy your hunger. People usually think of predators as meat-eating mammals carnivoresbut the bird, reptile, amphibian, fish, and insect families also have their predators.
Eagles, hawks, falcons, and owls are probably the best-known predators of the bird world. Everyone knows how one of them can swoop down, catch and kill a small creature, and then use a sharp-edged, hooked beak to tear bite-sized pieces of flesh from the animal. Because they feed on small mammals, are these birds more cruel than the fish-eating pelicans, gulls, terns, herons, egrets, and kingfishers or the insect-eating woodpeckers, flycatchers, warblers, swallows, swifts, and chickadees?
Although their food preferences are different, they are all predatory birds killing to satisfy their hunger. You probably won't have any problem recognizing the alligator member of the reptile family as a predator because it eats anything it can catch, either in the water or on land.
Snakes also are known for catching and swallowing a variety of creatures, but how many of you stopped to realize that a lizard that eats insects is also a predator? A couple of other quick-tongued predators, the frog and the toad, belong to the amphibian family. Would you put the lizard, frog, and toad in the same category with the alligator? All are predators, killing and eating in order to survive.

Sharks are probably the most feared predators of the sea, but are their eating habits, although vicious, any more predatory than those of the freshwater bass? From the time it is large enough to eat some of its own brothers and sisters to the time it can swallow a frog or baby duck swimming on the water's surface, the black bass spends its time searching its watery world for things to eat.
If it weren't for its predatory habits, we wouldn't be able to catch the bass with all the different kinds of baits and lures we use. That fish-shaped lure looks like a real fish and that plastic worm looks like a real worm or small snake to the hungry bass.
Although many insects feed on each other, the one you are probably the most familiar with is the spider. It sits in its web and patiently waits for an insect to get caught in its sticky trap. When this happens, the spider rushes out, kills or paralyzes the insect, wraps it in silk, and then sucks out its body liquids.
You may be thinking at this point that the predator has the best life, with nothing to worry about except catching its next meal. But did you know that many animals are both predators and prey? When a spider is sitting in its web waiting for its insect meal, it is the predator.
