Pseudechis Butleri
The spotted mulga snake (''Pseudechis butleri''), also known commonly as Butler's black snake and Butler's snake, is a species of venomous snake in the family Elapidae. The species is endemic to Western Australia. It is a member of the genus ''Pseudechis'', dangerously venomous snakes that can intimidate an opponent by raising the head and presenting a hood. This cobra-like threat display is supported by the ability to produce a very large amount of venom. Taxonomy The first description of the species ''P. butleri'' emerged in a study of morphological variation of the widespread species '' P. australis'', known commonly as the king brown or mulga snake. The author, Laurie Smith, examined a large series of specimens, allocating 213 to ''P. australis'' and 21 to the new species. The holotype of ''P. butleri'' is a female specimen, carrying eggs, collected at the Yalgoo region in 1963 by I. C. Carnaby. The suggestion of a cryptic ''Pseudechis'' species in the midwest was noticed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern States Of Australia
The eastern states of Australia are the states adjoining the east continental coastline of Australia. These are the mainland states of Victoria, New South Wales and Queensland, and the island state of Tasmania. The Australian Capital Territory and Jervis Bay Territory, while not states, are also included. On some occasions, the southern state of South Australia is also included in this grouping due to its economic ties with the eastern states. Regardless of which definition is used, the eastern states include the great majority of the Australian population. They contain the federal capital Canberra and Australia's three largest cities Sydney, Melbourne and Brisbane (all capitals of the respective east coast states), as well as the three largest non-capital cities in the country: Gold Coast, Queensland; Newcastle, New South Wales; and Wollongong, New South Wales. In terms of climate, the area is dominated by a humid subtropical zone, with some tropical (Queensland) and oceani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudechis Porphyriacus
The red-bellied black snake (''Pseudechis porphyriacus'') is a species of venomous snake in the family Elapidae, indigenous to Australia. Originally described by George Shaw in 1794 as a species new to science, it is one of eastern Australia's most commonly encountered snakes. Averaging around in length, it has glossy black upperparts, bright red or orange flanks, and a pink or dull red belly. It is not aggressive and generally retreats from human encounters, but can attack if provoked. Although its venom can cause significant illness, no deaths have been recorded from its bite, which is less venomous than other Australian elapid snakes. The venom contains neurotoxins, myotoxins, and coagulants and has haemolytic properties. Victims can also lose their sense of smell. Common in woodlands, forests and swamplands, the red-bellied black snake often ventures into nearby urban areas. It forages in bodies of shallow water, commonly with tangles of water plants and logs, where it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dorsal Scale
In snakes, the dorsal scales are the longitudinal series of plates that encircle the body, but do not include the ventral scales. Campbell JA, Lamar WW (2004). ''The Venomous Reptiles of the Western Hemisphere''. Ithaca and London: Comstock Publishing Associates. 2 volumes. 870 pp. 1,500 plates. . When counting dorsal scales, numbers are often given for three points along the body, for example 19:21:17. These numbers correspond to the number of dorsal scales around the body at a head's length behind the head, at midbody and at a head's length before the vent. If only one number is given, it is for the midbody count. Dorsal scale are easiest to count diagonally, starting with the paraventral scale row. In doing so, it is often noted that certain scale rows are raised, keeled or smooth as opposed to the others.U.S. Navy (1991). ''Poisonous Snakes of the World''. United States Government.

Ventral Scales
In snakes, the ventral scales or gastrosteges are the enlarged and transversely elongated scales that extend down the underside of the body from the neck to the anal scale. When counting them, the first is the anteriormost ventral scale that contacts the paraventral (lowermost) row of dorsal scales on either side. The anal scale is not counted.Campbell JA, Lamar WW. 2004. The Venomous Reptiles of the Western Hemisphere. 2 volumes. Comstock Publishing Associates, Ithaca and London. 870 pp. 1500 plates. .

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 Osteological correlates are marks on the bones of animals that are made from the causal interactions of the soft-tissue Soft tissue is all the tissue in the body that is not hardened by the processes of ossification or calcification such as bo ... such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Front-fanged
A snake skeleton consists primarily of the skull, vertebrae, and ribs, with only vestigial remnants of the limbs. Skull The skull of a snake is a very complex structure, with numerous joints to allow the snake to swallow prey far larger than its head. The typical snake skull has a solidly ossified braincase, with the separate frontal bones and the united parietal bones extending downward to the basisphenoid, which is large and extends forward into a rostrum extending to the ethmoidal region. The nose is less ossified, and the paired nasal bones are often attached only at their base. The occipital condyle is either trilobate and formed by the basioccipital and the exoccipitals, or a simple knob formed by the basioccipital; the supraoccipital is excluded from the foramen magnum. The basioccipital may bear a curved ventral process or hypapophysis in the vipers. The prefrontal bone is situated, on each side, between the frontal bone and the maxilla, and may or may not be in con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harry Butler
William Henry "Harry" Butler (25 March 1930 – 11 December 2015) was an Australian naturalist and environmental consultant, best known as the presenter of the popular ABC television series ''In the Wild'' from 1976 to 1981. He was a household name as he took viewers to remote parts of Australia observing and admiring the natural environment. Harry was a warrior for the environment and biodiversity. He spoke highly of how Indigenous people cared for the land, through his extensive experience growing up with various aboriginal groups. His advocacy led to the establishment of offshore islands as reserves for plants and animals, protected from invasive species. Now his legacy is being remembered with Murdoch University’s Harry Butler Institute. The new research and education facility brings science, business and the community together to address environmental problems. Biography Butler was born on 25 March 1930 in Perth, Western Australia.

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...
