Central Bearded Dragon
The central bearded dragon (''Pogona vitticeps''), also known as the inland bearded dragon, is a species of Agamidae, agamid lizard found in a wide range of arid to semiarid regions of eastern and central Australia. Taxonomy ''Pogona vitticeps'' was first species description, described by German zoologist Ernst Ahl in 1926, who placed it in the genus ''Amphibolurus''. Description Mature bearded dragons can reach a total length of around , or two feet, with the tail accounting for more than half of that. Some sexual dimorphism is present, as males can be distinguished from females by a wider Cloaca, cloacal opening, a wider tail-base, a larger and more angular head, a more developed beard (Guttural pouch, guttural throat-pouch), and the obvious possession of hemipenes. Males also have more pronounced femoral pores than females (these can be seen as waxy bumps on the underside of the back legs). Bearded dragons can vary widely in scale colouration, ranging from a blend of light b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frankfurt Zoological Garden
The Frankfurt Zoological Garden is the zoo of Frankfurt, Germany. It features over 4,500 animals of over 510 species on more than 11 hectares. The zoo was founded in 1858 and is the second oldest zoo in Germany, after Berlin Zoological Garden. It lies in the eastern part of the Innenstadt (inner city). Bernhard Grzimek was director of the zoo after World War II from 1945 until 1974. The Frankfurt Zoological Society (FZS) was founded in 1858 by citizens of Frankfurt to establish the Zoological Garden, which it operated until the First World War World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers.

Chameleon
Chameleons or chamaeleons (Family (biology), family Chamaeleonidae) are a distinctive and highly specialized clade of Old World lizards with 200 species described as of June 2015. The members of this Family (biology), family are best known for their distinct range of colours, being capable of colour-shifting camouflage. The large number of species in the family exhibit considerable variability in their capacity to change colour. For some, it is more of a shift of brightness (shades of brown); for others, a plethora of colour-combinations (reds, yellows, greens, blues) can be seen. Chameleons are also distinguished by their zygodactylous feet, their prehensility, prehensile tail, their laterally compressed bodies, their head casques, their projectile tongues used for catching prey, their swaying gait, and in some species crests or horns on their brow and snout. Chameleons' eyes are independently mobile, and because of this the chameleon’s brain is constantly analyzing two sepa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Third Eye
The third eye (also called the mind's eye or inner eye) is an invisible eye, usually depicted as located on the forehead, supposed to provide perception beyond ordinary sight. In Hinduism, the third eye refers to the ajna (or brow) chakra. In both Hinduism and Buddhism, the third eye is said to be located around the middle of the forehead, slightly above the junction of the eyebrows, representing the Enlightenment in Buddhism, enlightenment one achieves through meditation. Especially in Eastern world, Eastern spiritual practices, the third eye refers to the gate that leads to the inner realms and spaces of higher consciousness, and often symbolizes a state of enlightenment. The third eye is often associated with vision (religion), religious visions, clairvoyance, the ability to observe chakras and aura (paranormal), auras,. precognition, and out-of-body experiences.

Parietal Eye
A parietal eye (third eye, pineal eye) is a part of the epithalamus in some vertebrates. The eye is at the top of the head; is photoreceptive; and is associated with the pineal gland, which regulates circadian rhythmicity and hormone production for thermoregulation. The hole that contains the eye is known as the pineal foramen or parietal foramen, because it is often enclosed by the parietal bones. The parietal eye was discovered by Franz Leydig, in 1872, from work with lizards. Discovery Franz Leydig, a professor of zoology at the University of Tübingen, dissected four species of European lizards—the slow worm ('' Anguis fragilis'') and three species of '' Lacerta''. in 1872; He found cup-like protrusions under the middles of their brains. He believed the protrusions to be glandular and called them frontal organs (German ''Stirnorgan''). In 1886, Walter Baldwin Spencer, an anatomist at the University of Oxford, reported the results of his dissection of 29 species of li ...

Circadian Rhythm
A circadian rhythm (), or circadian cycle, is a natural oscillation that repeats roughly every 24 hours. Circadian rhythms can refer to any process that originates within an organism (i.e., Endogeny (biology), endogenous) and responds to the environment (is Entrainment (chronobiology), entrained by the environment). Circadian rhythms are regulated by a circadian clock whose primary function is to rhythmically co-ordinate biological processes so they occur at the correct time to maximize the fitness of an individual. Circadian rhythms have been widely observed in animals, plants, fungi and cyanobacteria and there is evidence that they evolved independently in each of these kingdoms of life. The term ''circadian'' comes from the Latin ', meaning "around", and ', meaning "day". Processes with 24-hour cycles are more generally called diurnal rhythms; diurnal rhythms should not be called circadian rhythms unless they can be confirmed as endogenous, and not environmental.

Endogeny (biology)
Endogeny, in biology, refers to the property of originating or developing from within an organism, Tissue (biology), tissue, or Cell (biology), cell. For example, ''endogenous substances'', and ''endogenous processes'' are those that originate within a living system (e.g. an organism or a Cell (biology), cell). For instance, estradiol is an endogenous estrogen hormone produced within the body, whereas ethinylestradiol is an exogenous synthetic estrogen, commonly used in birth control pills. In contrast, ''Exogeny#Biology, exogenous substances'' and ''exogenous'' ''processes'' are those that originate from outside of an organism.

Black
Black is a color that results from the absence or complete absorption of visible light. It is an achromatic color, without chroma, like white and grey. It is often used symbolically or figuratively to represent darkness.Eva Heller, ''Psychologie de la couleur – effets et symboliques'', pp. 105–26. Black and white have often been used to describe opposites such as good and evil, the Dark Ages versus the Age of Enlightenment, and night versus day. Since the Middle Ages, black has been the symbolic color of solemnity and authority, and for this reason it is still commonly worn by judges and magistrates. Black was one of the first colors used by artists in Neolithic cave paintings. It was used in ancient Egypt and Greece as the color of the underworld. In the Roman Empire, it became the color of mourning, and over the centuries it was frequently associated with death, evil, witches, and magic. In the 14th century, it was worn by royalty, clergy, judges, and governm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beard
A beard is the hair that grows on the jaw, chin, upper lip, lower lip, cheeks, and neck of humans and some non-human animals. In humans, beards are most commonly seen on pubescent or adult males, though women have been observed with beards as well. Throughout the course of human history, societal attitudes toward male beards have varied widely depending on factors such as prevailing cultural traditions and the current era's fashion trends. Several religions have considered a full beard to be essential and mandate it as part of their observance. Other cultures, even while not officially mandating it, view a beard as central to a man's virility, exemplifying such virtues as virtue, beauty, wisdom, strength, fertility, sexual prowess, and high social status. In cultures where facial hair is uncommon (or currently out of fashion), beards may be associated with poor hygiene or an unconventional demeanor. In countries with colder climates, beards help protect the wearer's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frilled Lizard
The frilled lizard (''Chlamydosaurus kingii)'', also known commonly as the frilled agama, the frillneck lizard, the frill-necked lizard, and the frilled dragon, is a species of lizard in the family Agamidae. The species is native to northern Australia and southern New Guinea and is the only member of the genus ''Chlamydosaurus''. Its common names refer to the large frill around its neck, which usually stays folded against the lizard's body. The frilled lizard grows to from head to tail tip and can weigh . Males are larger and more robust than females. The lizard's body is generally grey, brown, orangish-brown, or black in colour. The frills have red, orange, yellow, or white colours. The frilled lizard is largely arboreal, spending most of its time in trees. Its diet consists mainly of insects and other invertebrates. It is more active during the wet season, when it spends more time near or on the ground, and is less observed during the dry season, during which it seeks sha ...

Dingo
The dingo (either included in the species ''Canis familiaris'', or considered one of the following independent taxa: ''Canis familiaris dingo'', ''Canis dingo'', or ''Canis lupus dingo'') is an ancient (basal (phylogenetics), basal) lineage of dog found in Australia. Its taxonomy, taxonomic classification is debated as indicated by the variety of scientific names presently applied in different publications. It is variously considered a form of domestic dog not warranting recognition as a subspecies, a subspecies of dog or wolf, or a full species in its own right. The dingo is a medium-sized Canis, canine that possesses a lean, hardy body adapted for speed, agility, and stamina. The dingo's three main coat colourations are light ginger or tan, black and tan, or creamy white. The skull is wedge-shaped and appears large in proportion to the body. The dingo is closely related to the New Guinea singing dog: their lineage split early from the lineage that led to today's domestic do ...
