Echis carinatus (Schneider, 1801)
Saw-scaled Viper is a nocturnal species which remains active from late evening to late nights for foraging and other life activities. Can be seen at day time while basking on habitat. Activity usually terrestrial but climbs on scrub vegetation for basking. Locomotion slow and use side winding motion for creeping faster. Behavior very alert, aggressive and quick to respond. This is one of the fastest striking snake and takes much less than 1 second time to bite and back to its original place. On provocation it makes a specific coil to keep the head on front and middle of the coil which is followed by mutual rubbing of oblique scales present on flank. This rubbing produce fascinating sound of "working of saw". Strikes very fast when enemy approaches to its attacking range and delivers small but very potent amount of venom even by scratching only. Mating season starts with male combats. Reproduction ovoviviparous, female directly gives birth to 6-8 young individuals during summer to monsoon months.
Feeds on rodents, lizards, frogs, rarely on other snakes, insects includig.
Major threats are habitat destruction despite the fact that its well adopted to live in ignored lands and rocky terrain. Killing due to its venom potency and road kills are other major causes. For its venom it has been exploited in numbers and usually collected from field which are not protected and ignored.
