Skinks Of Australia
Skinks are a type of lizard 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. Etymology The word ''skink'', which entered the English language around 1580–1590, comes from classical Greek and Latin , names that referred to various specific lizards. 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 hav ...

Cenomanian
The Cenomanian is, in the International Commission on Stratigraphy's (ICS) geological timescale, the oldest or earliest age (geology), age of the Late Cretaceous epoch (geology), Epoch or the lowest stage (stratigraphy), stage of the Upper Cretaceous series (stratigraphy), Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zootaxa
''Zootaxa'' is a peer-reviewed scientific mega journal for animal taxonomists. It is published by Magnolia Press (Auckland, New Zealand). The journal was established by Zhi-Qiang Zhang in 2001 and new issues are published multiple times a week. From 2001 to 2020, more than 60,000 new species have been described in the journal accounting for around 25% of all new taxa indexed in The Zoological Record in the last few years. Print and online versions are available. Temporary suspension from JCR The journal exhibited high levels of self-citation and its journal impact factor of 2019 was suspended from ''Journal Citation Reports'' in 2020, a sanction which hit 34 journals in total. Biologist Ross Mounce noted that high levels of self-citation may be inevitable for a journal which publishes a large share of new species classification. Later that year, this decision was reversed and it was admitted that levels of self-citation are appropriate considering the large proportion of p ...

Biliverdin
Biliverdin (from the Latin for green bile) is a green tetrapyrrolic bile pigment, and is a product of heme catabolism.Boron W, Boulpaep E. Medical Physiology: a cellular and molecular approach, 2005. 984–986. Elsevier Saunders, United States. It is the pigment responsible for a greenish color sometimes seen in bruises. Metabolism Biliverdin results from the breakdown of the heme moiety of hemoglobin in erythrocytes. Macrophages break down senescent erythrocytes and break the heme down into biliverdin along with hemosiderin, in which biliverdin normally Biliverdin reductase, rapidly reduces to free bilirubin. Biliverdin is seen briefly in some bruises as a green color. In bruises, its breakdown into bilirubin leads to a yellowish color. Role in disease Biliverdin has been found in excess in the blood of humans suffering from hepatic diseases. Jaundice is caused by the accumulation of biliverdin or bilirubin (or both) in the circulatory system and tissues. Jaundiced skin ...

Prasinohaema
''Prasinohaema'' ( Greek: "green blood") is a genus of skinks characterized by having green blood. This condition is caused by an excess buildup of the bile pigment biliverdin. ''Prasinohaema'' species have plasma biliverdin concentrations approximately 1.5-30 times greater than fish species with green blood plasma and 40 times greater than humans with green jaundice. The benefit provided by the high pigment concentration is unknown, but one possibility is that it protects against malaria. Geographic range Species in the genus ''Prasinohaema'' are endemic to New Guinea and the Solomon Islands. Species Species in the genus include:. www.reptile-database.org. *'' Prasinohaema flavipes'' – common green tree skink *'' Prasinohaema parkeri'' – Parker's green tree skink *'' Prasinohaema prehensicauda'' – prehensile green tree skink *'' Prasinohaema semoni'' – Semon's green tree skink *'' Prasinohaema virens'' - green-blooded skink, green tree skink ''Nota bene'': A bi ...

Solomon Islands Skink
The Solomon Islands skink (''Corucia zebrata''), also known as prehensile-tailed skink, monkey-tailed skink, giant skink, zebra skink, and monkey skink, is an arboreal species of skink endemic to the Solomon Islands archipelago. It is the largest known extant species of skink. The Solomon Islands skink is completely herbivorous, eating many different fruits and vegetables including the pothos plant. It is one of the few species of reptile known to function within a social group or circulus. Both male and female specimens are known to be territorial and often hostile towards members not a part of their family group. ''Corucia'' is a monotypic genus, containing a single species. However, in 1997 it was determined that there are two subspecies of the Solomon Islands skink: the common monkey-tailed skink (''Corucia zebrata zebrata'') and the northern monkey-tailed skink (''Corucia zebrata alfredschmidti)''. Among other variances, the northern skink is smaller and has darker ey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scincella Lateralis
''Scincella lateralis'', formerly Lygosoma laterale is a small species of skink found throughout much of the eastern half of the United States, and into northern Mexico. The ground skink differs from the majority of North American lizard species in that it is generally considered a forest dweller. Common names for this species include the little brown skink and the ground skink. However, the common name, ground skink, may refer to any species in the genus ''Scincella''. Description The little brown skink is one of the smallest reptiles in North America, with a total length (including tail) of only 3 - 5.5 inches (7.5 - 14.5 cm)and 1 to 2 grams in body mass. Its back is typically a copper (color), coppery brown color with a white or yellow underside, dark coloration running laterally from eyes to tail and like most skinks has an elongated body and short legs. Transparent disks in the lower eyelids allow it to see with its eyes closed (Beane 2006, Palmer et al. 1995). Fema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regeneration (biology)
Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cell (biology), cells, organisms, and ecosystems Resilience (ecology), resilient to natural fluctuations or events that cause disturbance or damage. Every species is capable of regeneration, from bacteria to humans. Regeneration can either be complete where the new tissue is the same as the lost tissue, or incomplete after which the necrotic tissue becomes Fibrosis, fibrotic. At its most elementary level, regeneration is mediated by the molecular processes of gene regulation and involves the cellular processes of cell proliferation, morphogenesis and cell differentiation. Regeneration in biology, however, mainly refers to the Morphogenesis, morphogenic processes that characterize the phenotypic plasticity of Phenotypic trait, traits allowing multi-cellular organisms to repair and maintain the integrity of their physiological and morphological states. Above the genetic level, rege ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snake
Snakes are elongated limbless reptiles of the suborder Serpentes (). Cladistically squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales much like other members of the group. Many species of snakes have skulls with several more joints than their lizard ancestors and relatives, 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 only have one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have independently evolved elongate bodies without limbs or with greatly reduced limbs at least twenty-five times 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, althoug ...

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 can ...

Neoseps
The Florida sand skink (''Plestiodon reynoldsi'') is a species of lizard in the Family (biology), family Scincidae, the skinks. It is endemism, endemic to Florida in the United States. Taxonomy and etymology It was described as a new genus and new species by Leonhard Stejneger in 1910 and named in honor of a certain Mr. A.G. Reynolds of Gulfport, Florida, who had collected the holotype.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Neoseps reynoldsi'', p. 220). Description A unique lizard adapted to an underground existence, the Florida sand skink measures in total length and is a gray to tan color. Its forelegs are tiny and bear only one toe each; its hindlegs are small and have two toes. The tail comprises about half of the animal's total length. The sand skink has a wedge-shaped head, a partially countersunk lower jaw, body grooves into which the forelegs can be fol ...

Tribolonotus Gracilis
''Tribolonotus gracilis'', commonly known as the red-eyed crocodile skink or New Guinea crocodile skink, is a species of skink that is endemic to New Guinea, where it lives in tropical rainforest habitats. It was first described by Nelly de Rooij in 1909. It is sometimes kept as an exotic pet. Behavior ''Tribolonotus gracilis'' is one of the few species of skink Skinks are a type of lizard belonging to the family (biology), family Scincidae, a family in the Taxonomic rank, infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one o ...s that vocalize when in distress. When startled, they tend to freeze and have been known to "play dead" (even when handled). Reproduction A male red-eyed crocodile skink can be identified by the white pads (pores) on his feet. Female red-eyed crocodile skinks have two working ovaries, but only the right oviduct is functional; therefore, eggs from the left ovary must mig ...
