Lialis Jicari
The Papua snake lizard (''Lialis jicari)'', also known commonly as Jicar's snake-lizard, the New Guinea snake-lizard, and the Papua snake-lizard, is a species of legless lizard in the family Pygopodidae. The species is endemic to New Guinea including the Bismarck Archipelago. Etymology The specific name, ''jicari'', is in honor of Mr. A.H. Jiear, a Resident Magistrate in British New Guinea, who presented the holotype to the British Museum (Natural History). Boulenger misread the donor's surname as "Jicar". Habitat ''L. jicari'' is found in a variety of habitats including freshwater wetlands, grassland, shrubland, savanna, and forest, at altitudes from sea level to . Description ''L. jicari'' is limbless. It may attain a snout-to-vent length (SVL) of , with a tail length of . It has 22 scales around the middle of the body, seven preanal pores, and six anal scales. de Rooij N (1915). ''The Reptiles of the Indo-Australian Archipelago. I. Lacertilia, Chelonia, Emydosauria''.

Pygopodidae
Pygopodidae, commonly known as snake-lizards, or flap-footed lizards, are a Family (biology), family of Legless lizard, legless lizards with reduced or absent limbs, and are a type of gecko. The 47 species are placed in two subfamilies and eight Genus, genera. They have unusually long, slender bodies, giving them a strong resemblance to snakes. Like snakes and most geckos, they have no eyelids, but unlike snakes, they have external ear holes and flat, unforked tongues. They are native to Australia and New Guinea. Pygopodids have no fore limbs at all, but they do possess vestigial hind limbs in the form of small, flattened flaps. These may have some role in courtship and defensive behaviour, and may even aid in locomotion through vegetation. Some species are insectivore, insectivorous burrowing animals, but others are adapted to moving through dense Triodia (grass), spinifex or other vegetation.

Legless Lizard
Legless lizard may refer to any of several groups of lizards that have independently lost limbs or reduced them to the point of being of no use in locomotion.Pough ''et al.'' 1992. Herpetology: Third Edition. Pearson Prentice Hall:Pearson Education, Inc., 2002. It is the common name for the family Pygopodidae. These lizards are often distinguishable from snakes on the basis of one or more of the following characteristics: *possessing eyelids *possessing Outer ear, external ear openings *lack of broad belly scales *notched rather than forked tongue, forked tongue *having two lungs of roughly equal size (snakes have one short and one very long lung) *having a very long tail (while snakes have a long body and short tail).

Lizard Genera
Lizard is the common name used for all Squamata, squamate reptiles other than snakes (and to a lesser extent amphisbaenians), encompassing over 7,000 species, ranging across all continents except Antarctica, as well as most Island#Oceanic islands, oceanic Archipelago, island chains. The grouping is Paraphyly, paraphyletic as some lizards are more closely related to snakes than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards") have secondarily lost their legs, and have long snake-like bodies. Some lizards, such as the forest-dwelling ''Draco (genus), Draco'', are able to glide. They are often Territory (animal), territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

John Edward Gray
John Edward Gray (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Shine
Richard "Rick" Shine is an Australian evolutionary biologist and ecologist; he has conducted extensive research on reptiles and amphibians, and proposed a novel mechanism for evolutionary change. He is currently a Professor of Biology at Macquarie University, and an Emeritus Professor at The University of Sydney. Early life and education Richard Shine was born in Brisbane. He attended schools in Melbourne, Sydney, and Canberra, and completed his university studies at the Australian National University with an Honours degree in zoology in 1971. His PhD was obtained from the University of New England in Armidale, under the supervision of Professor Harold F. Heatwole, and dealt with the field ecology of Australian venomous snakes. It was the first detailed ecological research on these animals. He also began working on broader questions in evolutionary biology, collaboratively with another student, James J. Bull, currently a Professor in Biology at the University of Idaho. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oviparity
Oviparous animals are animals that reproduce by depositing fertilized zygotes outside the body (i.e., by laying or spawning) in metabolically independent incubation organs known as eggs, which nurture the embryo into moving offsprings known as hatchlings with little or no embryonic development within the mother. This is the reproductive method used by most animal species, as opposed to viviparous animals that develop the embryos internally and metabolically dependent on the maternal circulation, until the mother gives birth to live juveniles. Ovoviviparity is a special form of oviparity where the eggs are retained inside the mother (but still metabolically independent), and are carried internally until they hatch and eventually emerge outside as well-developed juveniles similar to viviparous animals. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or f ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 taxonomy (biology), 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. Phylogeneti ...
