Skink
Skinks are lizards belonging to the family Scincidae, a family in the infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of lizards. Skinks are characterized by their smaller legs in comparison to typical lizards and are found in different habitats except arctic and subarctic regions. Description Skinks look like lizards of the family Lacertidae (sometimes called ''true lizards''), but most species of skinks have no pronounced neck and relatively small legs. Several genera (e.g., '' Typhlosaurus'') have no limbs at all. This is not true for all skinks, however, as some species such as the red-eyed crocodile skink have a head that is very distinguished from the body. These lizards also have legs that are relatively small proportional to their body size. Skinks' skulls are covered by substantial bony scales, usually matching up in shape and size, while overlapping. Other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sri Lanka
Sri Lanka (, ; si, ශ්රී ලංකා, Śrī Laṅkā, translit-std=ISO (); ta, இலங்கை, Ilaṅkai, translit-std=ISO ()), formerly known as Ceylon and officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, and southeast of the Arabian Sea; it is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. Sri Lanka shares a maritime border with India and Maldives. Sri Jayawardenepura Kotte is its legislative capital, and Colombo is its List of cities in Sri Lanka, largest city and financial centre. Sri Lanka has a population of around 22 million (2020) and is a multinational state, home to diverse cultures, languages, and ethnicities. The Sinhalese people, Sinhalese are the majority of the nation's population. The Tamils, who are a large minority group, have also played an influential role in the island's history.

Nessia
''Nessia'' is a genus of skinks, lizards in the Family (biology), family Scincidae. The genus is Endemism, endemic to Sri Lanka. Species in the genus ''Nessia'' are commonly known as snake skinks. Species The following nine species are recognized as being valid: *''Nessia bipes'' – two-legged nessia *''Nessia burtonii'' – Burton's nessia *''Nessia deraniyagalai'' – Deraniyagala's nessia *''Nessia didactyla'' – two-toed nessia *''Nessia gansi'' *''Nessia hickanala'' – Hickanala nessia *''Nessia layardi'' – Layard's nessia *''Nessia monodactyla'' – one-toed nessia *''Nessia sarasinorum'' – Müller's nessia ''Nota bene'': A Binomial nomenclature, binomial authority in parentheses indicates that the species was originally described in a genus other than ''Nessia''.

Reptiles Of Sri Lanka
This is a list of reptiles of Sri Lanka. The reptilian diversity in Sri Lanka is higher than the diversity of other vertebrates such as mammals and fish with 181 reptile species. All extant reptiles are well documented through research by many local and foreign scientists and naturalists. Sri Lankan herpetologist, Anslem de Silva largely studied the biology and ecology of Sri Lanka snakes, where he documented 96 species of land and sea snakes. Five genera are endemic to Sri Lanka - ''Aspidura'', ''Balanophis'', ''Cercaspis'', ''Haplocercus'', and ''Pseudotyphlops''. Out of them only five of the land snakes are considered potentially deadly and life threatening to humans. Among snakes, 54 are endemic to Sri Lanka. The total increased to 107 with new descriptions of ''Dendrelaphis'', ''Rhinophis'', ''Aspidura'' and ''Dryocalamus''. Lizard diversity in the island has been documented and studied by many local scientists and researchers such as Imesh Nuwan Bandara, Kalana Maduwage, Anj ...

Endemic Fauna Of Sri Lanka
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there ... species from South ...

Reptiles Described In 1934
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 ...
