Mario Giacinto Peracca
Mario Giacinto Peracca (21 November 1861, Turin – 23 May 1923, Turin) was an Italian herpetologist. He discovered zoology through his father, an amateur ornithologist. He started taking medical classes at the University of Turin, with his studies eventually turning to zoology. In 1886, he obtained his degree from the university under the direction of Michele Lessona (1823-1894). After graduation, he remained in Turin as an assistant to Lessona, and later Lorenzo Camerano (1856-1917), at the zoological institute. Here he worked until his retirement in 1920. At the zoological institute, he served as curator of herpetological collections. Among the specimens at the museum were reptiles and amphibians that were produced at his estate, where he kept a large temperature-controlled vivarium with tropical plants, containing animals that included giant salamanders and Galapagos tortoises. Many of his written works dealt with herpetological collections from South America and Af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frank Wall (herpetologist)
Colonel Frank Wall (21 April 1868 – 19 May 1950) was a physician and herpetologist who lived in Sri Lanka and India. Early life and education Wall was born in Colombo, Ceylon (now Sri Lanka). His father, George Wall, was responsible for initiating the study of natural history on the island. Wall was sent to England to be educated at Harrow School, the same school his father and brothers attended, and studied medicine in London before joining the Indian Medical Service in 1893.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . ("Wall", p. 279). Herpetology Sent to India under the British Raj, Wall continued to work there until 1925 and researched many animals, especially snakes. He collected numerous snakes, many of which are now in the collections of the British Museum and the Natural History Museum, London. Wall was a member of the Bombay Natural History Society and pub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colubrid
Colubridae (, commonly known as colubrids , from la, coluber, 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica. Description While most colubrids are not venomous (or have venom that is not known to be harmful to humans) and are mostly harmless, a few groups, such as genus ''Boiga'', can produce medically significant injuries. In addition, the boomslang, the twig snakes, and the Asian genus ''Rhabdophis'' have caused human fatalities. Some colubrids are described as opisthoglyphous (often called "rear-fanged"), meaning they have elongated, grooved teeth located in the back of their upper jaws. It is likely that opisthoglyphous dentition evolved many times in the history of snakes and is an evolutionary precursor to the fangs of vipers and elapids, which are located in the front of the mouth.

Snake
Snakes are elongated, limbless, carnivorous reptiles of the suborder Serpentes . Like all other squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads ( cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, although this rule is not universal (see Amphisbae ...

India
India, officially the Republic of India ( Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ...

Himalayas
The Himalayas, or Himalaya (; ; ), is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the planet's highest peaks, including the very highest, Mount Everest. Over 100 peaks exceeding in elevation lie in the Himalayas. By contrast, the highest peak outside Asia ( Aconcagua, in the Andes) is tall. The Himalayas abut or cross five countries: Bhutan, India, Nepal, China, and Pakistan. The sovereignty of the range in the Kashmir region is disputed among India, Pakistan, and China. The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain. Some of the world's major rivers, the Indus, the Ganges, and the Tsangpo– Brahmaputra, rise in the vicinity of the Himalayas, and their combined drainage basin is home to some 600 million people; 53 million people live in the Himalayas.

Reptiles Of India
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 arou ...

Reptiles Of Nepal
Wildlife diversity is a notable feature of Nepal. Because of the variance in climate, from tropical to arctic, Nepal has a large variety of plants and animals. Wildlife tourism is also a major source of tourism in the country. There are some animal species which are unique to Nepal, such as the spiny babbler. Nepal is also host to many rhododendron species. The wildlife of Nepal includes its flora and fauna. Nepal has established numerous national parks and reserves in order to protect its diverse fauna. Nepal is a biodiversity hot spot with ecoregions broadly comprising the mountainous ecoregion, the savanna and grasslands ecoregion of the terai (foothills), and the Rara Lake ecoregion, which has many endemic species. Legal protection Nepal has established numerous national parks and reserves in order to protect its diverse fauna ever since 1973, with the passing of the National Parks and Wildlife Conservation Act 2029 BS. There are four different "classes" of protection, rangi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
