(East Indian forest on the island, and is not yet found in native vegetation. It is gecko). It took around 6 min for the krait to swallow the prey, possible that the population is being kept in check by predation, after which the snake crossed the road and moved into the leaf as the boa population on this island is exceptionally dense litter. (Reynolds and Gerber 2012. J. Herpetol. 46:578–586). Bungarus caeruleus is known to feed on frogs, lizards, and other snakes (Whitaker and Captain 2016. Snakes of India, the Field Guide. Westland/DracoBooks, Chennai. 400 pp.). Recently, scavenging behavior of this snake has been reported from India (e.g., Mohapatra 2011. Herpetol. Rev. 42:436–437; Deshmukh BY JOSEPH BURGESS et al. 2016. IRCF Reptiles & Amphibians 23:169–170), which a common opportunistic foraging strategy in many snakes PHOTO (DeVault and Krochmal 2002.
