Cnemaspis Kandianus
The Kandyan day gecko or Kandyan rock gecko (''Cnemaspis kandiana'') is a species of diurnal gecko found in Sri Lanka. Description Its head is rather elongated; the snout is obtusely pointed, longer than the distance between the eye and the ear opening, l.5 the diameter of the orbit; the forehead is not concave; the ear opening is small and oval. Its body and limbs are rather slender; the hind limbs reach the axilla or the shoulder. Its digits are slender, the basal part is not dilated, scarcely wider than the distal, and with enlarged plates beneath. The snout is covered with suboval keeled granules; the rest of the head is minutely granulate; the rostral is twice as broad as deep, with median emargination and cleft above; the nostrils are pierced between the rostral and three or four nasals; seven or eight upper and as many lower labials are found; the mental is large and triangular, with a truncated posterior angle; numerous small chin-shields pass gradually into the gular gran ...

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...

Nelly De Rooij
Petronella Johanna Nelly de Rooij (30 July 1883 – 10 June 1964) was a Dutch zoologist and herpetologist. Biography De Rooij was born in Weesp, and she studied Medicine in Amsterdam until discrimination against her gender in Dutch law obliged her to continue her studies in Zurich. She studied the cardiovascular system of salamanders of the genus ''Andrias'', and she was awarded her Doctor of Philosophy by the University of Zurich in 1907. With her qualification she was able to return to Amsterdam where she became a curator at the museum of zoology within the University of Amsterdam.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011).

William Theobald
William Theobald (1829 – 31 March 1908) was a malacologist and naturalist on the staff of the Geological Survey of India serving in Burma, then a part of British India. Biography Very little is known of Theobald's early life. Theobald was referred to in official documents as "William Theobald, Junior". He arrived in Calcutta on the ship ''Hindostan'' via the Suez in March 1847 and worked as a volunteer in the coal exploration of the upper Damodar and Son valleys under David Williams. During this time Joseph Hooker visited him and they spent time together. Later Theobald became an assistant to John McClelland who took over the exploration from David Williams. He went to Burma in 1855 as a staff of the Geological Survey of India and took over the ''Pegu survey''. He returned Bengal on completion of the survey in 1873 to be appointed Deputy Superintendent of Bengal in 1876.Mabberley DJ (1985).

Species
In biology, a species is the basic unit of 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 produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, 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 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 specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diurnality
Diurnality is a form of plant and ethology, animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemerality, cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gecko
Geckos are small, mostly carnivorous lizards that have a wide distribution, found on every continent except Antarctica. Belonging to the infraorder Gekkota, geckos are found in warm climates throughout the world. They range from . Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (''Gekko gecko'') are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened. They are the most species-rich group of lizards, with about 1,500 different species worldwide. All geckos, except species in the family Eublepharidae lack eyelids; instead, the outer surface of the eyeball has a transparent membrane, the cornea. They have a fixed lens within each iris that enlarges in darkness to let in more light. Since they cannot blink, species without eyelids generally lick t ...

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 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 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. Other long established groups include the Moors, the Burghers ...

Cnemaspis
''Cnemaspis'' is a genus of diurnal (day) geckos found in Asia. With over 100 species, it is one of the most diverse genera of geckos. Molecular phylogenies suggest that the two regional groupings may form distinct clades which are not each other's closest relatives. Description Species in this genus have slender, clawed digits which are cylindrical or depressed at the base (rarely dilated); the distal phalanges are compressed, forming an angle with the basal portion of the digits, the lower surface of which has a row of plates. Their bodies are more or less depressed, granular or tubercular above. Tail not compressed. Pupil circular; eyelid distinct all round the eye. Males with or without pre-anal or femoral pores.

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 species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
