There is a strong evolutionary pressure for prey animals to avoid predators through camouflage, and for predators to be able to detect camouflaged prey. There can be a self-perpetuating coevolution, in the shape of an evolutionary arms race, between the perceptive abilities of animals attempting to detect the cryptic animal and the cryptic characteristics of the hiding species.
Since motion dazzle patterns would make animals more difficult to locate accurately when moving, but easier to see when stationary, there would be an evolutionary trade-off between motion dazzle and crypsis. [123] An animal that is commonly thought to be dazzle-patterned is the zebra.
Camouflage is an exciting animal adaptation that allows many different types of animals to blend in with their surroundings. The chameleon is one of the most recognizable animals that camouflages ...
Surviving in the wild is no easy feat, but thanks to evolution, many animals evade their predators with a clever deception of the eyes. Since the beginning of time animals have either adapted or ...
Camouflage is the concealment of animals or objects of military interest by any combination of methods that helps them to remain unnoticed. This includes the use of high-contrast disruptive patterns as used on military uniforms , but anything that delays recognition can be used as camouflage.
Many prey animals, and to defend against seed predation also seeds of plants, [55] make use of poisonous chemicals for self-defence. [ 51 ] [ 56 ] These may be concentrated in surface structures such as spines or glands, giving an attacker a taste of the chemicals before it actually bites or swallows the prey animal: many toxins are bitter ...
Male platypuses have sharp spurs on their back legs shaped like a canine tooth. These hollow spurs measure 0.59 to 0.71 inches long and connect to crural glands in the animal’s upper thighs.
Animal coloration, readily observable, soon provided strong and independent lines of evidence, from camouflage, mimicry and aposematism, that natural selection was indeed at work. [ 6 ] [ 7 ] [ 8 ] The historian of science Peter J. Bowler wrote that Darwin's theory "was also extended to the broader topics of protective resemblances and mimicry ...
