Sunning (behaviour)
Sunning or basking, sometimes also known as sunbathing, is a thermoregulatory or comfort behaviour used by humans and animals, especially birds, reptiles, and insects, to help raise their body temperature, reduce the energy needed for temperature maintenance or to provide comfort. They may also have additional functions of ridding animals of ectoparasites, bacteria, or excess moisture. Birds Birds adopt special postures when sunning, these may include spreading out their feathers, flattening their body on soil, showing either their upper parts to the Sun or facing the Sun. Some authors separate the behaviours into sun-basking and sun-exposure the former term used when the behaviour is strictly thermoregulatory in function while the latter term may be more appropriate if the behaviour serves functions other than raising body temperature. In some species, the sunbathing posture is adopted in very hot weather and the birds sometimes stay in close contact with hot soil. Birds may ...

Grey Heron Sunning3
Grey (more frequent in British English) or gray (more frequent in American English) is an intermediate color between black and white. It is a neutral or achromatic color, meaning that it has no Colorfulness#Chroma, chroma. It is the color of a cloud-covered sky, of wood ash, ash, and of lead. The first recorded use of ''grey'' as a color name in the English language was in 700 Common Era, CE.Maerz and Paul ''A Dictionary of Color'' New York:1930 McGraw-Hill Page 196 ''Grey'' is the dominant spelling in English language in Europe, European and Commonwealth English, while ''gray'' is more common in American English; however, both spellings are valid in both varieties of English. In Europe and North America, surveys show that gray is the color most commonly associated with Neutrality (philosophy), neutrality, conformity, boredom, uncertainty, old age, apathy, indifference, and modesty. Only one percent of respondents chose it as their color preferences, favorite color. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Gippsland Water Dragon
The Australian water dragon (''Intellagama lesueurii)'', which includes the eastern water dragon (''Intellagama lesueurii lesueurii)'' and the Gippsland water dragon (''Intellagama lesueurii howittii)'' subspecies, is a semi aquatic agamid species native to eastern Australia from Victoria northwards to Queensland. There may be a small introduced population on the south-east coast of South Australia. The Gippsland water dragon is generally the more southern of the two subspecies and the more cold adapted and heat sensitive. Visually distinguishing the Gippsland water dragon from the Eastern water dragon is relatively easy, as long as their skin is reasonably clean and not stained from the water, as identification of the two subspecies depends largely on observable differences in colours and patterns. The Gippsland water dragon may be distinguished by its green-blue colour, especially during the breeding season, when this overall colouration is quite distinct. Another key differenc ...

PARNASSIAN EVERSMANN'S (Parnassius Eversmanni) (6-25-2016) Denali Highway, Mile P13 Pass, Near Paxson, Alaska (1) (28494231274)
Parnassianism (or Parnassism) was a group of French poets that began during the positivist period of the 19th century (1860s–1890s), occurring after romanticism and prior to symbolism. The style was influenced by the author Théophile Gautier as well as by the philosophical ideas of Arthur Schopenhauer. Origins and name The name is derived from the original Parnassian poets' journal, ''Le Parnasse contemporain'', itself named after Mount Parnassus, home of the Muses of Greek mythology. The anthology was first issued in 1866 and again in 1871 and 1876, including poems by Charles Leconte de Lisle, Théodore de Banville, Sully Prudhomme, Stéphane Mallarmé, Paul Verlaine, François Coppée, Nina de Callias, and José María de Heredia. The Parnassians were influenced by Théophile Gautier and his doctrine of "art for art's sake". As a reaction to the less-disciplined types of romantic poetry and what they considered the excessive sentimentality and undue social and political ...

Pseudantechinus Macdonnellensis
The fat-tailed false antechinus (''Pseudantechinus macdonnellensis''), also called the fat-tailed pseudantechinus and red-eared antechinus, is a member of the order (biology), order Dasyuromorphia. It is an inhabitant of western and central Australia. Its species name, ''macdonnellensis'', refers to the MacDonnell Ranges near Alice Springs, where it was first discovered. Taxonomy Scientific name: ''Pseudantechinus macdonellensis''. Common name: Fat-tailed-antechinus, fat-tailed pseudantechinus. It was first described in 1896 by Sir Walter Baldwin Spencer, who placed it in the genus ''Phascogale''. It was for a long time included in the genus ''Antechinus''. The species has formerly included the Alexandria false antechinus (''P. mimulus''), the Ningbing false antechinus (''P. ningbing''), and Woolley's false antechinus (''P. woolleyae''). The ''P. macdonellensis'' is commonly found in the rocky environments of Central Australia. It is presumed to have a large population, and ge ...

Tabby Sunning After Winter In House
A tabby cat, or simply tabby, is any domestic cat (''Felis catus'') with a coat pattern distinguished by an M-shaped marking on its forehead, stripes by its eyes and across its cheeks, along its back, around its legs and tail, and characteristic striped, dotted, lined, flecked, banded, or swirled patterns on the body: neck, shoulders, sides, flanks, chest. The four known distinct patterns, each linked to genetics, are the mackerel, classic or blotched, ticked, and spotted tabby patterns. "Tabby" is not a breed of cat but a coat pattern. It is common among non-pedigree cats around the world. The tabby pattern occurs naturally and is connected both to the coat of the domestic cat's direct ancestor and to those of its close relatives: the African wildcat (''Felis lybica lybica''), the European wildcat (''Felis silvestris''), and the Asiatic wildcat (''Felis lybica ornata''), all of which have similar coats, both by pattern and coloration.

River Cooter
The river cooter (''Pseudemys concinna'') is a species of freshwater turtle in the family Emydidae. The species is native to the central and eastern United States, but has been introduced into parts of California, Washington, and British Columbia. Geographic range ''P. concinna'' is found from Virginia south to central Georgia, west to eastern Texas, Oklahoma, and north to southern Indiana. Habitat ''P. concinna'' is usually found in rivers with moderate current, as well as lakes and tidal marshes. Subspecies There are two subspecies which are recognized as being valid. *''Pseudemys concinna concinna'' – eastern river cooter *''Pseudemys concinna suwanniensis'' – Suwannee cooter – sometimes regarded as a separate species, ''P. suwanniensis'' ''Nota bene'': A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than ''Pseudemys''.

Pond Slider
The pond slider (''Trachemys scripta'') is a species of common, medium-sized, semiaquatic turtle. Three subspecies are described, the most recognizable of which is the red-eared slider (''T. s. elegans''), which is popular in the pet trade and has been introduced to other parts of the world by people releasing it to the wild. Hatchling and juvenile pond sliders have a green upper shell (carapace), yellow bottom shell (plastron The turtle shell is a shield for the ventral and dorsal parts of turtles (the Order (biology), order Testudines), completely enclosing all the turtle's vital organs and in some cases even the head. It is constructed of modified bony elements such ...), and green and yellow stripes and markings on their skin. These patterns and colors in the skin and shell fade with age until the carapace is a muted olive green to brown and the plastron is a dull yellow or darker. Some sliders become almost black with few visible markings. The carapace is oval with a bit of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Dimetrodon
''Dimetrodon'' ( or ; ) is an extinct genus of sphenacodontid synapsid that lived during the Cisuralian (Early Permian) Epoch (geology), epoch of the Permian period, around 295–272 million years ago. With most species measuring long and weighing , the most prominent feature of ''Dimetrodon'' is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It was an obligate Quadrupedalism, quadruped (it could walk only on four legs) and had a tall, curved skull with large teeth of different sizes set along the jaws. Most fossils have been found in the Southwestern United States, the majority of these coming from a geological deposit called the Red Beds of Texas and Oklahoma. More recently, its fossils have also been found in Germany and over a dozen species have been named since the genus was first erected in 1878. ''Dimetrodon'' is often mistaken for a dinosaur or portrayed as a contemporary of dinosaurs in popular culture, but it beca ...

Trachemys Scripta Elegans
The red-eared slider or red-eared terrapin (''Trachemys scripta elegans'') is a subspecies of the pond slider (''Trachemys scripta''), a semiaquatic turtle belonging to the family Emydidae. Native to the southern United States and extreme northern Mexico, it is popular as a pet across the world, and is the most invasive turtle. It is the most commonly traded turtle in the world. The red-eared slider is native to the Midwestern United States and northern Mexico, but has become established in other places because of pet releases, and has become invasive in many areas where it outcompetes native species. The red-eared slider is included in the list of the world's 100 most invasive species. Etymology The red-eared slider gets its name from the small, red stripe around its ears, or where its ears would be, and from its ability to slide quickly off rocks and logs into the water. This species was previously known as Troost's turtle in honor of an American herpetologist Gera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Thermoregulation
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation. The internal thermoregulation process is one aspect of homeostasis: a state of dynamic stability in an organism's internal conditions, maintained far from thermal equilibrium with its environment (the study of such processes in zoology has been called physiological ecology). If the body is unable to maintain a normal human body temperature, normal temperature and it increases significantly above normal, a condition known as hyperthermia occurs. Humans may also experience lethal hyperthermia when the wet bulb temperature is sustained above for six hours. Work in 2022 established by experiment that a wet-bulb temperature exceeding 30.55°C caused uncompensab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Crocodylus Palustris
The mugger crocodile (''Crocodylus palustris'') is a medium-sized broad-snouted crocodile, also known as mugger and marsh crocodile. It is native to freshwater habitats from south-eastern Iran to the Indian subcontinent, where it inhabits marshes, lakes, rivers and artificial ponds. It rarely reaches a body length of and is a powerful swimmer, but also walks on land in search of suitable waterbodies during the hot season. Both young and adult mugger crocodiles dig burrows to which they retreat when the ambient temperature drops below or exceeds . Females dig holes in the sand as nesting sites and lay up to 46 eggs during the dry season. The sex of hatchlings depends on temperature during incubation. Both parents protect the young for up to one year. They feed on insects, and adults prey on fish, reptiles, birds and mammals. The mugger crocodile evolved at least and has been a symbol for the fructifying and destructive powers of the rivers since the Vedic period. It was first ...
