Crack-dwelling Whipsnake

The soil-crack whipsnake is front fanged and average about 49 cm in length. They are a slender grey to olive brown, presenting a dark band behind the head and a belly that is bright orange-red. They have been identified as having moderately large stouts up to 740mm compared to other Demansia, and will often have dark spots on their heads. This is identified via a thin piece of tissue located near another teardrop marking., creating the illusion of 2 pale, merging blobs. This differentiates the soil-crack whip snake from other species as well as the nature of the head markings. In particular the markings on their head appear sharply angulated as 2 prominent diverging rows on their anterior ventral's. It once again becomes further differentiated from other species such as D. angusticeps and D. olivaea as its broad and dark nape band is edged with cream making it more prominent and consequently greater in size. The body has been described as mid-brown, yellow pigment on the scales which often have been concentrated centrally to give broad dark, and narrow pale stripes along the edge of the snake. They have also been found to have a throat which is strongly marbled with dark brown which dissipates posteriorly along the lateral ventral's.

Soil-crack whipsnakes can be found around Tibooburra and the Sturt National Park in far northwestern New South Wales.

This snake is mostly diurnal, using flat rocks, fallen timber, debris, rock crevices, deep soil crack, grass clumps and animal burrows for shelter. they prefer biomes of open forests, woodlands or shrubland that have plenty of grass and shrubs to live amongst. they're main food source is small lizards and snakes which they chase and hunt. The whipsnakes ecology has been specifically adapted to hunt prey which is fast moving. As there has been little study conducted on Demansia rimicola, it is often compared to other species of Demansia such as D. torquata, as their ecology seems to be very similar. When studying the ovulation of these animals, it was found that female reproductive cycles are strongly seasonal and will often ovulate in spring. In terms of body size, males seem to be larger in Eastern species of Demansia and this has strong to correlation to the idea of superiority within the species. It has been previously suggested that the main type of prey for Demansia is lizards, however it has been recently investigated that approximately 27% of their diet consists of vertebrate prey such as frogs. This is surprising especially considering the drier habitats which they live in. Whipsnakes have a unique style of hunting involving visually locating their prey of a daytime, and then hunting them of an evening when they are inactive usually by scent.
