Salamander (legendary Creature)
The salamander is an amphibian of the order Urodela which, as with many real creatures, often has been ascribed fantastic and sometimes occult qualities by pre-modern authors (as in the allegorical descriptions of animals in medieval bestiaries) not possessed by the real organism. The legendary salamander is often depicted as a typical salamander in shape with a lizard-like form, but is usually ascribed an affinity with fire, sometimes specifically elemental fire. Classical, Medieval, and Renaissance lore This legendary creature embodies the fantastic qualities that ancient and medieval commentators ascribed to the natural salamander. Many of these qualities are rooted in verifiable traits of the natural creature but often exaggerated. A large body of legend, mythology, and symbolism has developed around this creature over the centuries. Carl Linnaeus in the 10th edition of ''Systema Naturae'' of 1758 established the scientific description of the salamander and noted the chief char ...

Amphibian
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicander
Nicander of Colophon ( grc-gre, Νίκανδρος ὁ Κολοφώνιος, Níkandros ho Kolophṓnios; fl. 2nd century BC), Greek poet, physician and grammarian, was born at Claros (Ahmetbeyli in modern Turkey), near Colophon, where his family held the hereditary priesthood of Apollo. He flourished under Attalus III of Pergamum. He wrote a number of works both in prose and verse, of which two survive complete. The longest, '' Theriaca'', is a hexameter poem (958 lines) on the nature of venomous animals and the wounds which they inflict. The other, '' Alexipharmaca'', consists of 630 hexameters treating of poisons and their antidotes. Nicander's main source for medical information was the physician Apollodorus of Egypt. Among his lost works, '' Heteroeumena'' was a mythological epic, used by Ovid in the ''Metamorphoses'' and epitomized by Antoninus Liberalis; '' Georgica'', of which considerable fragments survive, was perhaps imitated by Virgil. The works of Nicander were pra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphrodisiac
An aphrodisiac is a substance that increases sexual desire, sexual attraction, sexual pleasure, or sexual behavior. Substances range from a variety of plants, spices, foods, and synthetic chemicals. Natural aphrodisiacs like cannabis or cocaine are classified into plant-based and non-plant-based substances. There are non-naturally-occurring aphrodisiacs like MDMA and methamphetamine. Aphrodisiacs can be classified by their type of effects (i.e., psychological or physiological). Aphrodisiacs that contain hallucinogenic properties like Bufotenin have psychological effects on a person that can increase sexual desire and sexual pleasure. Aphrodisiacs that contain smooth muscle relaxing properties like yohimbine have physiological effects on a person that can affect hormone levels and increase blood flow. It is possible that the aphrodisiac effect of a substance is due to the placebo effect. Other substances that impede on areas that aphrodisiacs aim to enhance are classified as an ...

Sextius Niger
Sextius Niger was a Roman writer on pharmacology during the reign of Augustus or a little later. He may be identical with the son of the philosopher Quintus Sextius, who continued his philosophical teachings. Life and work From Pedanius Dioscorides and Pliny the Elder, who mention his work, we can fix his time of writing to a period after Juba II, the king of Mauretania, had written his treatise on euphorbia, which Dioscorides and Pliny knew from Niger, and before Pliny himself wrote his '' Natural History'', in other words from late in the first century B.C. to the first half of the first century A.D. Caelius Aurelianus (''acut.'' 3, 16, 134) allows us to narrow the possible date further, by naming him as a friend of Tullius Bassus, who is cited by Scribonius Largus (121); since Scribonius wrote in the early to mid 40s, this should narrow his period to before 40 A.D. His pharmacological work was a '' materia medica'' written in Greek and, according to Erotianus, had the title ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural History (Pliny)
The ''Natural History'' ( la, Naturalis historia) is a work by Pliny the Elder. The largest single work to have survived from the Roman Empire to the modern day, the ''Natural History'' compiles information gleaned from other ancient authors. Despite the work's title, its subject area is not limited to what is today understood by natural history; Pliny himself defines his scope as "the natural world, or life". It is encyclopedic in scope, but its structure is not like that of a modern encyclopedia. It is the only work by Pliny to have survived, and the last that he published. He published the first 10 books in AD 77, but had not made a final revision of the remainder at the time of his death during the AD 79 eruption of Vesuvius. The rest was published posthumously by Pliny's nephew, Pliny the Younger. The work is divided into 37 books, organised into 10 volumes. These cover topics including astronomy, mathematics, geography, ethnography, anthropology, human physiolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Animals
''History of Animals'' ( grc-gre, Τῶν περὶ τὰ ζῷα ἱστοριῶν, ''Ton peri ta zoia historion'', "Inquiries on Animals"; la, Historia Animalium, "History of Animals") is one of the major texts on biology by the ancient Greek philosopher Aristotle, who had studied at Plato's Academy in Athens. It was written in the fourth century BC; Aristotle died in 322 BC. Generally seen as a pioneering work of zoology, Aristotle frames his text by explaining that he is investigating the ''what'' (the existing facts about animals) prior to establishing the ''why'' (the causes of these characteristics). The book is thus an attempt to apply philosophy to part of the natural world. Throughout the work, Aristotle seeks to identify differences, both between individuals and between groups. A group is established when it is seen that all members have the same set of distinguishing features; for example, that all birds have feathers, wings, and beaks. This relationship between ...

Reptile
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around ...

Scientific Classification
Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic units known as "taxa" (singular "taxon")." Taxonomy is different from m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degrees such as a bachelor's degree plus an advanced degree like a master's degree or a doctorate. Like other scientists, biologists can be fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salamandra Atra Aurorae
''Salamandra atra aurorae'' is a subspecies of the alpine salamander ''Salamandra atra'' found in south-eastern Italian Prealps. It is often called the golden alpine salamander. Morphology ''Salamandra atra aurorae'' is very similar in body shape to all other subspecies of '' S. atra'', also in all major characters that often distinguish different species of ''Salamandra'': outline of the head, position of the vomerine teeth, proportions of body parts and limbs, arrangement of glandular bulges and pores on the skin, and shape and length of the tail. However, the body surface is not entirely and uniformly black as in most other populations of '' ''S. atra''''. Conversely, the dorsal side of ''S. atra aurorae'' is broadly covered with yellow blotches and brown spots, which are broader and often coalescent on the head and the trunk, they are usually present also on the arms, the thighs and the tail, whereas they are rare on the flanks and the ventral sides. Blotches are invariantly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Thomas Riley
Henry Thomas Riley (June 1816 – 14 April 1878) was an English translator, lexicographer, and antiquary. Life Born in June 1816, he was only son of Henry Riley of Southwark, an ironmonger. He was educated at Chatham House, Ramsgate, and at Charterhouse School (1832–4). He entered Trinity College, Cambridge, but at the end of his first term migrated to Clare College where he was admitted on 17 December 1834, and elected a scholar on 24 January 1835. In 1838 he obtained a Latin essay prize. He graduated B.A. in 1840 and M.A. in 1859, after which he moved to Corpus Christi College. On 16 June 1870 he was incorporated at Exeter College, Oxford. Riley was called to the bar at the Inner Temple on 23 November 1847, but early in life he began hack work for booksellers to make a living, by editing and translation. On the creation of the Historical Manuscripts Commission (by royal charter in April 1869), Riley was engaged as an additional inspector for England, and given the task of e ...
