Crypsis

This supports the finds of previous research (Edmunds & Dewhist, 1994; Speed et al., 2005; Rowland 2007) that also showed a significant difference in predation amounts between these two prey groups. This result indicates that the two functions of countershading are responsible for the increase in crypsis and therefore the decrease in predation. Firstly, as self-shadow concealment is present in the countershaded prey and not the uniformly white prey lower detection occurred. This is due to the perception of three-dimensional bodies appearing less solid through concealing shadows (Thayer, 1896). However, self shadow concealment is largely dependent on the direction, and to a lessor degree, the intensity of the illumination (Hailman, 1977). For example, the diurnal change in sunlight angle falling upon prey may result in ineffective self shadow concealment (Hailman 1977; Kiltie 1988; Ruxton et al 2004a). Secondly, as countershaded prey matched their background when viewed from above, less contrast between the prey and background would be present. This reduction of contrast between the two indicates an increase in crypsis and a lower predation…

Move and Act As If someone is tracking you while in the Woods This is a Survival Habit That Anyone Can and Should Develop Camouflage, also called cryptic coloration, is a defense or tactic that animals and humans use to disguise their appearance, usually to blend in with their surroundings. Camouflage is used to disguise location, identity, and movement. Crypsis is simply blending into your surroundings to avoid detection and most humans would use cryptic coloration. In other words, mimic the…

Body size appears to play a part in whether or not frogs vocalize during escape. The smaller the frog the less likely they are to vocalize comparatively to that of a large or medium sized frog. Most female anurans are larger than males. In an attempt to avoid predators, small frogs tend to remain closer to water and are more likely to escape to the water, whereas larger frogs are initially further from water and typically are more likely to move to grassy areas in time of escape (Bateman 716).…

basking is mostly converted into heat so that the darker-coloured lizards can heat up quicker and achieve an equilibrium or a steady body temperature. Benefits in terms of thermal due to colour change depend on the absorptance of solar/ radiant heat energy in both UV-visible and near infrared (NIR) wavelengths. The results show that wild-caught bearded dragon can change colour to a magnitude at which provides thermoregulation benefits by having a higher dorsal skin reflectance (changing to a…

The audience is any person who works in an office space in addition to biologists and psychologists. One purpose of the article is to introduce a product that creates a solution to a common problem. Another purpose is to investigate crypsis, “the ability of an animal to camouflage itself and elude detection”, as well as the behavioral response of humans to devices of this nature. The genre of this article is a combination of a scientific report and the critique of a product. The Alan Burdick…

slender loris is part of the class Mammalia and the order primate. When observing the slender loris one may notice their large eyes. They are precisely in a forward facing position and set very close together, this feature takes up most of their faces. Their eyes are surrounded by dark grey circles of fur, which make them look even bigger than they are. Slender lorises have petite and sagittal rostrums, exceptionally slender appendages, and lack a post-anal tail. A grey or reddish coat of fur…

and underneath the eight hundred-mile long abyss populated by the indigenous Amphibia and Reptilia species. All major freeways and large lesser lanes have been completely flattened from inadequate reinforced concrete that supported the upper decks causing the lanes to collapse onto the lower decks. Thousands of drivers remain entombed beneath the tons of concrete and steel that compressed their vehicles. The beaches along the coastline are congested with debris from buildings and…
