Distribution

This is a species of wet hill forest tracts, mainly found along the Western Ghats (Agasthyamalai, High Wavy Mountains, Anaimalai, Nilgiris, Waynad, Coorg, Malnad region and Goa on to the Sahyadri range). Recently this species was also recorded in southern parts of the Eastern Ghats, in Tamil Nadu state (Sirumalai, Shevaroys, Kolli Hills, Melagiri and BR Hills). [2] This species prefers low to mid-elevation hills (300–1200 m asl), occurring in tropical evergreen and moist deciduous forests.

Morphology

Small to medium length, with a moderately long tail, reaching a maximum of about 1.2 meters. Head somewhat ovoid when viewed from above is distinct from neck with a rounded snout. Eyes are large in size with vertically elliptical pupils. Deep rusty brown with numerous, rich, reddish brown cross bars across. Underside creamy yellow densely powdered with brown spots. Dorsal scales smooth with single apical pits. The vertebral scale series is strongly enlarged. Ventral scales are laterally angulate. Dorsal scale count 21 (23) - 21 (23) - 15.

Behavior

Nocturnal and arboreal. Occasionally seen on the ground searching for prey. Generally of a mild disposition, but has been observed to strike when approached or cornered. If the snake is provoked it will raise its fore body, coil into loops, often vibrating its tail and bites readily.

Food

Especially feeds on Calotes but can eat tree frogs and geckos also, like other cat snake species.

The Eastern Ghats are a discontinuous range of mountains along India's eastern coast. The Eastern Ghats pass through Odisha, Andhra Pradesh to Tamil Nadu in the south passing some parts of Karnataka as well as Telangana. They are eroded and cut through by four major rivers of peninsular India, viz., Mahanadi, Godavari, Krishna, and Kaveri. Deomali with 1672 m height is the tallest point in Odisha. Arma Konda/Jindhagada Peak with 1680 m is the highest point in Andhra Pradesh. BR hill range located in Karnataka is the tallest hill range in Eastern Ghats with many peaks above 1750 m height. Kattahi Betta in BR hills with the height of 1822 m is the tallest peak in Eastern Ghats. Thalamalai hill range in Tamil Nadu is the second tallest hill range. Araku range is the third tallest hill range.

<i>Boiga</i> Genus of snakes

Boiga is a large genus of rear-fanged, mildly venomous snakes, known commonly as cat-eyed snakes or simply cat snakes, in the family Colubridae. Species of the genus Boiga are native to southeast Asia, India, and Australia, but due to their extremely hardy nature and adaptability, have spread to many other suitable habitats around the world. There are 38 recognized species in the genus. According to the study done by Jiří Smíd regarding Old World cat snakes, the ancestor of the cat snake originated in Africa, from where it diversified and expanded to other countries. Despite this diversity however, the different species have very similar needs in terms of temperature and precipitation.

It is a burrowing snake, presumed to be nocturnal, feeding on soft-bodied worms. It becomes active during the rains. U. shorttii has most recently been assessed for The IUCN Red List of Threatened Species in 2019, and is listed as "Critically Endangered" under criteria B1ab(iii).
