Ctenotus Joanae
''Ctenotus joanae'', also known commonly as the blacksoil ctenotus and the black-soil ctenotus, is a species of lizard in the subfamily Sphenomorphinae of the family Scincidae (skinks). The species is endemic to Australia. Etymology The specific name, ''joanae'', is in honor of Australian zoologist Joan Maureen Dixon. Beolens B, Watkins M, Grayson M (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Ctenotus joanae'', p. 135). Geographic range In Australia, ''C. joanae'' is found in the Northern Territory and in the states of Queensland and South Australia. Habitat The preferred natural habitat of ''C. joanae'' is grassland. Description ''C. joanae'' has five digits on each of its four feet.

Glen Milton Storr
Dr. Glen Milton Storr (22 December 1921 – 26 June 1990) was an Australian ornithologist and herpetologist. He joined the Western Australian Museum in 1962 and became Curator of Ornithology and Herpetology in 1965. He was a member of the Royal Australasian Ornithologists Union (RAOU), and served as Secretary of the Western Australian Branch of the RAOU in 1954. Storr produced his postgraduate research on kangaroos. His tenure as curator at the WA museum ended in 1986. Career Storr was born in Adelaide in 1921, and had become a cadet land surveyor with the South Australian Lands Department in 1939. World War II interrupted his training when he joined the Australian Infantry in 1942, serving with the Second Ninth Field Regiment in New Guinea and Queensland (1943-1945) Following the war, he became a licensed surveyor in South Australia in 1947. Legacy Storr was one of the most prolific alpha-taxonomists in herpetology, i.e. he described 232 species and subspecies of repti ...

Reptiles Described In 1970
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 ...

Ctenotus
''Ctenotus'' is a genus of skinks (family Scincidae). The genus belongs to a clade in the ''Sphenomorphus'' group which contains such genera as ''Anomalopus'' and the close relatives '' Eulamprus'' and '' Gnypetoscincus''. Lizards in the genus ''Ctenotus'' are commonly called comb-eared skinks, a reference to the scales aligned near the ear. ''Ctenotus'' lizards are able to move very quickly, disappearing whilst being observed. They are highly active in their habits, foraging amongst a diverse range of habitat. The members of the genus ''Ctenotus'' are widely distributed, in all states of Australia, and are especially diverse in arid regions and the tropical north, accounting for 10–20% of the lizard species. Around a quarter of lizards found in one area of the Great Sandy Desert are ''Ctenotus'' skinks, 11 of the 40 species. A single dune may have up to six species of ''Ctenotus''. The Southwest Australian region contains 23 species. The size ranges from very small to moder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harold Cogger
Harold George "Hal" Cogger (born 4 May 1935) is an Australian herpetologist. He was curator of reptiles and amphibians at the Australian Museum from 1960 to 1975, and Deputy Director of the museum from 1976 to 1995. He has written extensively on Australian herpetology, and was the first author to create a field guide for all Australian frogs and reptiles. Cogger was made an honorary Doctor of Science in 1997. At least eight reptile taxa have been named after Cogger, including one genus, six species, and one subspecies: '' Coggeria'', ''Ctenotus coggeri'', ''Emoia coggeri'', ''Geomyersia coggeri'', ''Hydrophis coggeri'', ''Lampropholis coggeri'', ''Oedura coggeri ''Oedura coggeri'', commonly known as the northern spotted velvet gecko, is a species of gecko, a lizard in the family Diplodactylidae.

Oviparity
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being '' Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snout–vent Length
Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most common measurement taken in herpetology, being used for all amphibians, lepidosaurs, and crocodilians (for turtles, carapace length (CL) and plastral length (PL) are used instead). The SVL differs depending on whether the animal is struggling or relaxed (if alive), or various other factors if it is a preserved specimen. For fossils, an osteological correlate such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Because tails are often missing or absent, especially in juveniles, SVL is seen as more invariant than total length. Even in the case of crocodiles, tail tips may be missing. Methods The measurements may be taken with dial calipers or digital calipe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Digit (anatomy)
A digit is one of several most distal parts of a limb, such as fingers or toes, present in many vertebrates. Names Some languages have different names for hand and foot digits (English: respectively " finger" and " toe", German: "Finger" and "Zeh", French: "doigt" and "orteil"). In other languages, e.g. Arabic, Russian, Polish, Spanish, Portuguese, Italian, Czech, Tagalog, Turkish, Bulgarian, and Persian, there are no specific one-word names for fingers and toes; these are called "digit of the hand" or "digit of the foot" instead. In Japanese, yubi (指) can mean either, depending on context. Human digits Humans normally have five digits on each extremity. Each digit is formed by several bones called phalanges, surrounded by soft tissue. Human fingers normally have a nail at the distal phalanx. The phenomenon of polydactyly occurs when extra digits are present; fewer digits than normal are also possible, for instance in ectrodactyly. Whether such a mutation ca ...
