Sommaire partiel
The present study deals with thorough investigation planned to evaluate the present eco status of various snake species occurred in terms of diversity, morphology, distribution, occurrence, natural history, habitat occupancy, and microclimatic variation in various micro-habitats of varied localities in the golden triangle (Jodhpur 26.2800° N, 73.0200° E, Jaisalmer 26.9200° N, 70.9000° E and Bikaner 28.0167º N, 73.3119º E districts) in the current outline.

To accomplice these objectives, comprehensive surveys and meticulous field visits conducted for four years starting from September 2015 onwards till August 2019 to explore the ophiological status in seven localities (Jodhpur city area, Osian, Bilada, Balesar, Dechu, Lohawat, and Bap) of Jodhpur, five localities (Jaisalmer city, Desert National Park, Mohangarh, Lathi and Pokhran) in Jaisalmer and seven localities (Bikaner city, Jorbeer conservation reserve, Kolayat, Chhatargarh, Poogal, Khajuvala and Nokha) of Bikaner district. Based on habitats’ potentiality, routine visits organized a minimum of twice in three months in each locality every year. Information gathered from the local rescuers, forest officials, and local people for the idea of a snake’s presence. Snake hook used to handle the snake for all the species where possible and careful handling performed while obtaining the morphological and measurement data. No sample collection performed during the study period. Venomous snakes measured only the snake found as a fresh road kill or with the help of photos taken by a high quality digital camera in the field area.

A Canon 70D digital camera used for high-quality pictures of snakes for both day and night-active species. Hand-held GPS devices used to access every location’s geographical position where a snake found in the habitat. Also, a digital hygrometer used for the record temperature and humidity of the particular locality where the snake located. Snake hook and stick used to handle all the snakes where possible. The species identified with head shield arrangement, coloration, and matching with the standard field guides. Natural history studies have done careful observation of the snake species in the wild and obtained morphological and measurement-based data such as snout-vent length, tail length, mid-dorsal scale count, head shield arrangement, and coloration, activity pattern, and their behavior
