Cryptoblepharus australis, commonly called the inland snake-eyed skink, [2] is a species of skink in the genus Cryptoblepharus . [1] [3]

Pronunciation: KRIP-toe-BLEFF-ah-russ / oss-TRAH-liss

Etymology

Cryptoblepharus: ‘hidden eyelid’, referring to the fused eyelids.

Australis: ‘southern’, or more generally referring to Australia

Introduction

A major and much-needed revision of the genus was undertaken in 2007 by Paul Horner of the Northern Territory Museum, previously splitting this species into a bunch of species each of which occupies quite a distinct range occurring over Australia.

Paul Horner (2008), says Cryptoblepharus are unique species to the Territory. A study recently has found the top end is a hot spot for snake eyed skinks with one new discovery that was very exciting for herpetologist Paul Horner (2008).

Description of species

C. australis usually has quite distinct features: 6 supraciliary scales, 24 mid-body scale rows; smooth sub digital lamellae; immaculate, acute plantar scales. They are greyish in colour and have a longitudinal aligned body pattern. [2] Cryptoblepharus snaked-eyed skink species live on vertical surfaces of rocks, trees and buildings which are challenging habitats that demand quite different adaptions and body characteristics. [4] These physical characteristics include a dorsally depressed body and long splayed limbs, digits which create a low centre of gravity and an intimate contact with the surface. [4] These little skinks are as swift and sure footed vertically as they are horizontally on a plane. [4]

Similar species include; Metallic snake-eyed skink (Cryptoblepharus metallicus) Adams' snake-eyed skink (Cryptoblepharus adamsi) Fuhn's snake-eyed skink (Cryptoblepharus fuhni) Cryptoblepharus litoralisCryptoblepharus virgatus, wall skink

[2]

Distribution

It is distributed across arid inland Australia, extending north to vicinity of Barkley Highway in the Northern Territory and Queensland, east to the central plains of Queensland, east to the central plains of Queensland and New South Wales, and south Eyre Peninsula in South Australia. In Western Australia, it is known from Murchison and Great Victoria Desert bioregions [2] For more of an idea, it is found in the interior of the state including these places; ‘Binerah Downs’ station, Yetman area, Armidale and Wahgunyah State Forest [5]

Habitat

The Cryptoplepharus australis lives in; Semi-arid zone, woodland, open woodland, shrub land, grasslands, spinifex type environment [6]

Habits

It is an arboreal (tree dwelling), rock inhabiting and diurnal (active during the day), in a natural environment they are found under bark on standing trees, and crevices in the dead timber and rocks. [5] Snake eyed skinks even occupy the walls of buildings well within the central business districts such as Perth and Cairns. [4] The Crytoplepharus genus species ‘Snake eyed Skink’ as mentioned above thrives on vertical surfaces of rocks, trees and buildings which are challenging habitats that demand quite different adaptations. [4]

Threats

General threats to all reptiles include:

habitat loss from land clearing habitat degradation by introduced species such as cattle and rabbits habitat modification caused by global climate change death on roads feral predators such as dogs, cats, pigs and foxes the introduced cane toad emerging diseases [2]

Reproduction

It produces two eggs to a clutch. [5]

Diet

Its diet consists of insects. [5]

Skink family of reptiles

Skinks are lizards belonging to the family Scincidae and the infraorder Scincomorpha. With more than 1,500 described species, the Scincidae are one of the most diverse families of lizards. Common skinks include many different kinds such as the slender skink, snake-eyed skink and the skinks of the genus Plestiodon are among the common skinks.

Cryptoblepharus virgatus, also commonly known as striped snake-eyed skink, cream-striped shinning-skink, wall skink, fence skink or snake-eyed skink is a skink commonly found in southern and eastern Australia. It is an active little lizard, and if threatened will often play dead to confuse the attacker.

Australian snake habitats

Australia’s landmass is 7,617,930 square kilometres. Due to the country's large landmass, many climates are experienced including equatorial, tropical, subtropical, desert, monsoonal, temperate, and alpine. These differing climates influence Australia's snake distribution and abundance, and provide many different and unique habitats for them.

Excitable delma species of reptile

The excitable delma 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. The 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 legless lizard is an insectivore and feeds off 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.
