Keeled scales of a colubrid snake (banded water snake; Nerodia fasciata) In zoology, a scale (Ancient Greek: λεπίς, romanized: lepís; Latin: squāma) is a small rigid plate that grows out of an animal's skin to provide protection. In lepidopterans (butterflies and moths), scales are plates on the surface of the insect wing, and provide ...
The simple or complex colouration patterns (which help in camouflage and anti-predator display) are a property of the underlying skin, but the folded nature of scaled skin allows bright skin to be concealed between scales then revealed in order to startle predators.
The shape and number of scales on the head, back and belly are characteristic to family, genus and species. Scales have a nomenclature analogous to the position on the body. In "advanced" (Caenophidian) snakes, the broad belly scales and rows of dorsal scales correspond to the vertebrae, allowing scientists to count the vertebrae without ...
Hope everyone at the zoo has been eating healthy! The London Zoo performed its annual weigh-in for its animals on Wednesday. Over 17,000 animals had their height and weight recorded as part of the ...
The body or 'blade' of a typical scale consists of an upper and lower lamina. The surface of the lower lamina is smooth whereas the structure of the upper lamina is structured and intricate. Scales are attached to the substrate by a stalk or 'pedicel'. [1] The scales cling somewhat loosely to the wing and come off easily without harming the insect.
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages.
Ryan said an animal’s weight is vital information that can reveal whether creatures are healthy, and even which are pregnant. “We have critically endangered animals here,” she said.
Water collection has been shown in some rattlesnakes, though the nanostructure of the scales is thought to be more significant than the macrostructure (keel) of the scales. [6] In some viperines, most notably those of the genus Echis, the lateral scales are not only keeled, but the keels have minute serrations. The snakes use this in a warning ...
