Dugite Discovery SHY, SCALY PREDATOR Dugites Are Quite Common Around Perth and Are Most Likely to Be Seen During the Daytime in Warmer Months ED!MAY 13, 2020 Dugite discovery SHY, SCALY PREDATOR Dugites are quite common around Perth and are most likely to be seen during the daytime in warmer months. They are one of the native species that have benefited from urbanisation, which has brought with it new food sources and places to shelter. Most snake bites that occur around Perth are from dugites. While they are generally shy, they will attack if they feel threatened. They are listed as the 13th most venomous snake in the world by the Australian Venom Research Unit.

  • Reptiles in and Around the House Identification and Distribution Reptiles Inhabit Every Environment in Australia
    Reptiles in and around the house Identification and Distribution Reptiles inhabit every environment in Australia. Common reptiles found in Western Australian backyards include: Tiger snakes Notechis scutatus occur in southwest WA, and are often seen near water, including rivers, dams, drains and wetlands. Unlike most other Australian elapids, tiger snakes climb well. They can range from grey, olive, brown to black in colour and often have yellow and black cross-bands, but not all have this pattern. Venomous Dugite. Photo: R. Lloyd/Fauna Track Dugites Pseudonaja affinis occur in southwest WA and Gwarda Pseudonaja nuchalis occur from Perth northwards. They live in a wide variety of habitats including coastal dunes, heathlands, shrublands, woodlands and forests. They are long and slender, with relatively large scales that have a semi-glossy appearance. They can range from brown, olive to grey in colour, and can have irregular black/dark grey spotting, but patterning varies. Venomous Mulga snakes Pseudechis australis occur in a wide variety of habitats, northwards from Perth and Narrogin. They are quite robust, with a broad, deep head and bulbous cheeks. They can range from pale brown, dark olive to reddish-brown in colour, and darker snakes often have two-toned scales with a lighter colour that contrasts with the darker colour to produce a reticulated effect. The belly is cream to salmon-coloured. Venomous There are two subspecies of carpet pythons found in a large variety of habitats in WA: Morelia spilota imbricata occurs in the southwest and Morelia spilota variegata occurs in the Kimberley. They are 1-4m in length, tend to be pale to dark brown with black blotches that sometimes have a Carpet python.

  • Does Urbanization Influence the Diet of a Large Snake?

FLEMING aDepartment of Environment and Agriculture, Curtin University, Perth, Bentley, WA, 6102, Australia and bSchool of Veterinary and Life Sciences, Murdoch University, Perth, Murdoch, WA, 6150, Australia *Address correspondence to Ashleigh K. Wolfe. E-mail: [email protected] Received on 10 April 2017; accepted on 21 May 2017 Abstract Urbanization facilitates synanthropic species such as rodents, which benefit the diets of many preda- tors in cities. We investigated how urbanization affects the feeding ecology of dugites Pseudonaja affi- nis, a common elapid snake in south-west Western Australia. We predicted that urban snakes: 1) more frequently contain prey and eat larger meals, 2) eat proportionally more non-native prey, 3) eat a lower diversity of prey species, and 4) are relatively heavier, than non-urban dugites. We analyzed the diet of 453 specimens obtained from the Western Australian Museum and opportunistic road-kill collections. Correcting for size, sex, season, and temporal biases, we tested whether location influenced diet for our 4 predictions. Body size was a strong predictor of diet (larger snakes had larger prey present, a greater number of prey items, and a greater diversity of prey). We identified potential collection biases: urban dugites were relatively smaller (snout-vent length) than non-urban specimens, and females were relatively lighter than males. Accounting for these effects, urban snakes were less likely to have prey present in their stomachs and were relatively lighter than non-urban snakes.

  • Taxonomy of the Genus Pseudonaja (Reptilia: Elapidae) in Australia
    AUSTRALIAN BIODIVERSITY RECORD ________________________________________________________ 2002 (No 7) ISSN 1325-2992 March, 2002 ________________________________________________________ Taxonomy of the Genus Pseudonaja (Reptilia: Elapidae) in Australia. by Richard W. Wells “Shiralee”, Major West Road, Cowra, New South Wales, Australia The clear morphological differences that exist within the genus as previously considered strongly indicate that it is a polyphyletic assemblage. Accordingly, I have taken the step of formally proposing the fragmentation of Pseudonaja. In this work I have decided to restrict the genus Pseudonaja to the Pseudonaja nuchalis complex. Additionally, I herein formally resurrect from synonymy the generic name Euprepiosoma Fitzinger, 1860 for the textilis group of species, erect a new generic name (Placidaserpens gen. nov.) for the snakes previously regarded as Pseudonaja guttata, erect a new generic name (Notopseudonaja gen. nov.) for the group of species previously regarded as the Pseudonaja modesta complex, and erect a new generic name (Dugitophis gen. nov.) for snakes previously regarded as the Pseudonaja affinis complex. Genus Pseudonaja Gunther, 1858 The Pseudonaja nuchalis Complex It is usually reported that Pseudonaja nuchalis occurs across most of northern, central and western Australia, ranging from Cape York Peninsula, in the north-east, through western, southern and south-eastern Queensland, far western New South Wales, north-western Victoria, and most of South Australia, Northern Territory and Western Australia. However, this distribution pattern is now known to actually represents several different species all regarded by most authorities for convenience as the single highly variable species, 'Pseudonaja nuchalis'. As usually defined, this actually is a highly variable and therefore confusing group of species to identify and it is not all surprising that there has been difficulty in breaking up the group.

Illustrated is that a tremendous structural homology exists among the components but this homology is not representative of the functional diversity. Further, the review illuminates the overlooked species and areas of research. # 1998 Elsevier Science Ltd. All rights reserved. 1. Introduction Australian elapids are well known to be the most toxic in the world, with all of the top ten and nineteen of the top 25 elapids with known LD50s residing exclusively on this continent (Broad et al., 1979). Thus far, three main types of venom components have been characterised from Australian elapids: prothrombin activating enzymes; lipases with a myriad of potent activities; and powerful peptidic neurotoxins. Many species have the prothrombin activating enzymes in their venoms, the vast majority contain phospholipase A2s and all Australian elapid venoms are suspected to contain peptidic neurotoxins. In addition to the profound neurological eects such as disorientation, ¯accid paralysis and respiratory failure, characteristic of bites by many species of Australian elapids is hemorrhaging and incoagulable blood. As a result, these elapids can be divided into two main classes: species with procoagulant venom (Table 1) and species with non-procoagulant venoms (Table 2) (Tan and * Author to whom correspondence should be addressed. 0041-0101/98/$ - see front matter # 1998 Elsevier Science Ltd.

  • Ontogenetic Shift in Diet of a Large Elapid Snake Is Facilitated by Allometric Change in Skull Morphology

Read Full License Page 1/30 Abstract As snakes are limbless, gape-limited predators, their skull is the main feeding structure involved in prey handling, manipulation and feeding. Ontogenetic changes in prey type and size are likely to be associated with distinct morphological changes in the skull during growth. We investigated ontogenetic variation in diet from stomach contents of n = 161 dugite specimens (Pseudonaja anis, Elapidae) representing the full range of body size for the species, and skull morphology of 46 specimens (range 0.25–1.64 m snout- vent-length; SVL). We hypothesised that changes in prey type throughout postnatal ontogeny would coincide with distinct changes in skull shape. Dugites demonstrate a distinct size-related shift in diet: the smallest individuals ate autotomised reptile tails, medium-sized individuals predominantly ate small reptiles (as snakes grew larger there was an increased likelihood of feeding on reptiles head-rst), and the largest individuals (> 0.8 m SVL) ate mammals and large reptiles.

Alarmingly high numbers of animal (and plant) species hover just this side of oblivion. Not infrequently in Australia‘s natural history the first sighting of an animal by a colonial collector is followed fairly swiftly by a long disappearance. Very few come back. For the most part, expanding populations of exotic predators and feral competitors, combined with shrinking islands of natural habitats mean that the average Australian has few chances to experience firsthand even the commonest creatures of this continent. These days, the closest many people come to direct contact with an indigenous mammal is via the roo bars on their oversized four-wheel-drive vehicles.

    Snakes of the Perth Metropolitan Area by G. M. Storr and R. E. Johnstone, Western Australian Museum Snakes are much-maligned animals. Yet most of the world's 3 000-odd species are harmless; less than 2% are dangerous to man or to his livestock and pets. It is therefore a good idea to learn which snakes are dangerous and which should be spared. But first one must distinguish snakes from other elongate limbless creatures.
