![]() ![]() Cannibalism amongst wild tiger snakes has also been reported. Invertebrates have also been found in tiger snake stomachs however these could have been taken as part of carrion other taxa such as grasshoppers and moths however may have been ingested as prey. A bat was found in the stomach of one museum specimen, demonstrating the tiger snake’s ability to climb. They will readily search underwater and can stay under for at least 9 minutes. Tiger snakes are largely diurnal and hunt for prey during the daylight hours however they will forage on warm evenings. As the size of the snake increases, so to does the average prey size, however this increase is achieved not by larger snakes giving up on small prey but by them taking more large prey. Tiger snakes in the wild have a broad diet that includes fish, frogs and tadpoles, lizards, birds and mammals, as well as carrion. As many as 26 neonates, perhaps all from one late season litter, have been found together in a winter shelter. During cool periods they will aestivate in animal burrows, under large boulders and in standing dead trees, and may go as deep as 1.2m underground. Snakes are typically more active during the warmer months, however tiger snakes may also be found out basking on warm winter days. A large squarish frontal shield, not or scarcely longer than broad, is characteristic of Notechis. Midbody scales 17-21 rows, ventral scales 140-190, single anal and subcaudal scales. The neck and upper body can be flattened to a considerable degree when performing a threat display, exposing the black skin between the relatively large, semi-glossy scales. The head is moderately wide and deep and only slightly distinct from the robust, muscular body. The dark colouration is an adaptation that allows those snakes to absorb heat at a faster rate during the short growing season. ![]() Melanism (dark body colouration) is most strongly developed in populations exposed to highly variable weather conditions and cool extremes, such as those experienced at higher altitudes or on offshore islands. those of the central highlands and southwest of Tasmania. Some populations consist of almost entirely unbanded individuals, e.g. Entirely patternless individuals may occur in banded populations, and these types range in colour from yellowish-brown to black. The most commonly seen form is dark olive brown to blackish-brown, with off-white to yellowish cross-bands that can vary in thickness. The common name refers to the prominent yellow and black cross-bands typical of some populations of tiger snakes, however not all have this pattern.
