Ophisaurus Hainanensis
''Ophisaurus'' (from the Greek 'snake-lizard') is a genus of superficially snake-like legless lizards in the subfamily Anguinae. Known as joint snakes, glass snakes, or glass lizards, they are so-named because their tails are easily broken; like many lizards, they have the ability to deter predation by autotomy, dropping off part of the tail, which can break into several pieces, like glass. The tail remains mobile, distracting the predator, while the lizard becomes motionless, allowing eventual escape. This serious loss of body mass requires a considerable effort to replace, and can take years to do so. Despite this ability, the new tail is usually smaller than the original. Although most species have no legs, their head shapes, movable eyelids, and external ear openings identify them as lizards. A few species have very small, stub-like legs near their rear vents. These are vestigial organs, meaning they once served an evolved purpose but are no longer used. They reach lengths of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Glass Lizard
The eastern glass lizard (''Ophisaurus ventralis'') is a species of legless lizard in the Family (biology), family Anguidae and the longest and heaviest species of glass lizards in the genus ''Ophisaurus'', Endemism, endemic to the Southeastern United States. The streamlined, legless species is often confused with Snake, snakes. Glass lizards differ from snakes as they possess a moveable eyelid and an external ear opening as well as a lateral groove that separates the different types of scales on the animal, all three of these features are absent in snakes. Snakes also have flexible jaws while lizards do not. ''Ventralis'' comes from the Latin "venter" meaning belly; this is in reference to the snake-like movement. Description Adults of ''O. ventralis'' grow to in total length, although the head-body length is only at most. There are 99 or more scales along the lateral groove. In this species, no dark longitudinal stripes are present below the lateral groove or under the tail, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxono ...

Ophisaurus Mimicus
The mimic glass lizard (''Ophisaurus mimicus'') is a species of lizard in the family Anguidae. The species is endemic to the Southeastern United States. The mimic glass lizard is dark brown to black with a dark middorsal stripe down the body and on most of the tail. They have 3-4 dark stripes separated by pale stripes above the lateral grooves. They have a very distinct anatomy of the axis specifically when it comes to their second vertebra which could be attributed to an ecological adaptation, feeding, and/or defensive behavior that requires high head and neck mobility. Geographic range ''Ophiosaurus mimicus'' was historically found in parts of Florida, Georgia, Mississippi, North Carolina, and South Carolina, although recent observations are confined to very small patches of remaining habitat in Florida, North Carolina, and Alabama. They are narrowly associated with longleaf pine forests where they tend to prefer frequently burned areas with seasonally saturated soils. We ...

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontology, paleontologist, comparative anatomy, comparative anatomist, herpetology, herpetologist, and ichthyology, ichthyologist. Born to a wealthy Quaker family, he distinguished himself as a child prodigy interested in science, publishing his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the Western United States, American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey, U.S. Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition now known as the Bone Wars. Cope's financial fortunes soured after failed mining ventures i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ophisaurus Attenuatus
The slender glass lizard (''Ophisaurus attenuatus'') is a legless lizard in the glass lizard subfamily ( Anguinae). The species is endemic to the United States. Two subspecies are recognized. The lizard was originally believed to be a subspecies of the eastern glass lizard (''Ophisaurus ventralis''). Their name comes from their easily broken tail which they can break off themselves without ever being touched. It is difficult to find a specimen with an undamaged tail. The lizard eats a variety of insects and small animals, including smaller lizards. Snakes and other animals are known to prey on the species. Humans have a part in destroying their environment and killing their food supply with insecticides. The lizard is considered to be a least-concern species according to the International Union for Conservation of Nature (IUCN), though it is vulnerable in Iowa and endangered in Wisconsin. The streamlined, legless species is often confused with snakes. Glass Lizards, however, diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sensu Stricto
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case). Three such phrases are: * – "in the strict sense", abbreviation ''s.s.'' or ''s.str.''; * – "in the broad sense", abbreviation ''s.l.''; * – "in a relaxed, generous (or 'ample') sense", a similar meaning to ''sensu lato''. Søren Kierkegaard uses the phrase ''sensu eminenti'' to mean "in the pre-eminent r most important or significantsense". When appropriate, comparative and superlative adjectives may also be used to convey the meaning of "more" or "most". Thus ''sensu strict ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
