Most forms of camouflage are ineffective when the camouflaged animal or object moves, because the motion is easily seen by the observing predator, prey or enemy. [74] However, insects such as hoverflies [ 75 ] and dragonflies use motion camouflage : the hoverflies to approach possible mates, and the dragonflies to approach rivals when defending ...
The alligator snapping turtle (Macrochelys temminckii) is a well-camouflaged ambush predator. Its tongue bears a conspicuous pink extension that resembles a worm and can be wriggled around; [ 13 ] fish that try to eat the "worm" are themselves eaten by the turtle.
Some predators, like the leopard, and some potential prey like the Egyptian nightjar, use disruptive patterns. [4] Disruptive patterns are defined by A. Barbosa and colleagues as "characterized by high-contrast light and dark patches, in a nonrepetitive configuration, that also provide camouflage by disrupting the recognizable shape or ...
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.
For instance nightjars are nocturnal, and rest, well camouflaged, on the ground during the day. Chapter 8. Concealment In offence. Cott describes the care that predators take when approaching prey, minimizing visible movement and scent, the use of cover for ambush, and "adaptive silence". Chapter 9.
A camouflaged orange oak leaf butterfly, Kallima inachus (centre) has protective resemblance. Protective resemblance is used by prey to avoid predation. It includes special protective resemblance, now called mimesis, where the whole animal looks like some other object, for example when a caterpillar resembles a twig or a bird dropping.
It is the basis of camouflage in both predators and prey. [18] It is used alongside other forms of camouflage including colour matching and disruptive coloration. [ 18 ] Among predatory fish, the gray snapper , Lutianus griseus , is effectively flattened by its countershading, while it hunts an "almost invisible" prey, the hardhead silverside ...
Leaf insects are well camouflaged, taking on the appearance of leaves. They do this so accurately that predators often are not able to distinguish them from real leaves. In some species, the edge of the leaf insect's body has the appearance of bite marks.
