It is also called Westermann's snake, reflecting its scientific name.[1] The snake belongs to the monotypic genus Elachistodon. EtymologyThe specific name, westermanni, is in honor of Dutch zoologist Geraldus Frederick Westermann (1807–1890).[2] Geographic rangeThe Indian egg-eating snake is found in Bangladesh, India, and Nepal. Recent discoveries of the species come from Maharashtra, Gujarat, Punjab, Madhya Pradesh and Telangana.[3][4][5][6] DescriptionThis species is glossy brown to black, with bluish white flecks posteriorly and a middorsal creamy stripe from neck to tail tip. The head is brown with a black arrow mark. The ventrals are white with brown dots. Adults may attain a total length of 78 cm (31 inches), with a tail 11 cm (4¼ inches) long.[7] BehaviourThe Indian egg-eating snake is a diurnal[1] or nocturnal, terrestrial species that shows remarkable dexterity in scaling vegetation. When provoked, it raises the anterior portion of the body, forming ‘S’ shaped coils as a defensive strategy.[6] DietIt exclusively feeds on bird eggs that lack embryonic growth. It has special adaptations such as vertebral hypapophyses, projections of the cervical vertebrae, that jut into the oesophagus, are enamel-capped, and help in cracking eggs.[7] The only other snakes that share these egg-eating adaptations are in the genus Dasypeltis found in Africa.[8] References1. ^1 2 {{cite journal | vauthors = Srinivasulu C, Srinivasulu B, Vyas R, Thakur S, Mohapatra P, Giri V | title = Elachistodon westermanni | journal = IUCN Red List of Threatened Species | volume= 2013 | page = e.T7091A3136878 | year = 2013 | doi = 10.2305/IUCN.UK.2013-1.RLTS.T7091A3136878.en }} 2. ^Beolens, Bo; Watkins, Michael; Grayson, Michael (2011).
