Delma Tincta
The excitable delma (''Delma tincta'') is a species of lizard in the Pygopodidae family endemic to Australia. The lizard gets its name from its active and jumpy defense mechanism. It will erratically jump multiple times in succession, each jump pivoting its body in a different direction. ''D. tincta'' is a slender, long legless lizard that through evolution lost its limbs. It is found throughout Australia in a variety of habitats, and spends most of its time hiding. Due to its nocturnal nature, it is rare to spot in the wild. This legless lizard is small to moderate in size, with a tail that is three to four times its body length. The typical size of the excitable delma is 250 – 300 mm. This lizard is an insectivore and feeds on insects it finds when travelling through grass, logs, surface soil, and loose rocks. Like all pygopodids, the excitable delma is oviparous and only lays two eggs per clutch. Taxonomy The excitable delma is officially classified as ''Delma ti ...

Delma Molleri
''Delma molleri'' (commonly known as Gulfs delma and Adelaide delma) is a small he snout-vent length of the largest specimen measured limbless lizard found in southern South Australia around the Adelaide Hills, and pretty common in Adelaide suburbs. ''Delma molleri'' has been recorded from a variety of habitats ranging from grassland to woodland beneath rocks, timber, and rubbish. The species is oviparous. The nucleotide ( DNA/RNA) and protein sequences of ''D. molleri'' have been sourced through the European Nucleotide Archive (ENA) and Universal Protein Resource (UniProt) databases. The identification of the species as an Australian-dwelling organism has been achieved by accessing the Australian Plant Census (APC) and the Australian Faunal Directory (AFD) through the Atlas of Living Australia. Etymology The specific name, ''molleri'', is in honor of Danish ship's captain Möller who brought the holotype A holotype is a single physical example (or illustration) of an ...

Observational Study
In fields such as epidemiology, social sciences, psychology and statistics, an observational study draws inferences from a sample (statistics), sample to a statistical population, population where the dependent and independent variables, independent variable is not under the Scientific control, control of the researcher because of ethical concerns or logistical constraints. One common observational study is about the possible effect of a treatment on subjects, where the assignment of subjects into a treated group versus a control group is outside the control of the investigator. This is in contrast with experiments, such as randomized controlled trials, where each subject is Random assignment, randomly assigned to a treated group or a control group. Observational studies, for lacking an assignment mechanism, naturally present difficulties for inferential analysis. Motivation The independent variable may be beyond the control of the investigator for a variety of reasons: * A ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

In reptiles, the supralabial scales, also called upper-labials, are those scales that border the mouth opening along the upper jaw. They do not include the median scaleWright AH, Wright AA. 1957.

Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. The theory of evolution by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snake
Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales. Many species of snakes have skulls with several more joints than their lizard ancestors, 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 have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently 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, altho ...

Collared Delma
The collared delma or adorned delma (''Delma torquata'') is the smallest species of lizard in the Pygopodidae family Endemism, endemic to Australia. Pygopopdids are legless lizards, so are commonly mistaken for snakes. They are distributed mainly across south-east Queensland and northern New South Wales, in both forests and some suburban areas. They are active during the day, seen foraging and hunting for small insects. Physical appearance The colour of the collared delma changes between its tail, body, and head, having a bluish/grey tinge, with its body being brown while its head is black with cream/yellow, ringed interspaces. These rings are a distinctive feature of the collared delma, and it usually has one around its head and two to three rings around its neck. In size, the snout-vent length of a collared delma can range from 50 to about 70 mm, with its tail length ranging from 103 to 126 mm and having an average weight of around 1.36 kg.
