Lowland Hump-nosed Pit Viper/පහතරට මූකලන් තෙලිස්සා[Pahatharata Mukalantelissa] (Hypnale zara)

An endemic snake restricted to the lowland rain forests of the south-western wet zone up to foot hills of the central highlands.  It is a nocturnal snake and during the day time stay hidden under decaying logs and leaf litter on the forest floor. Maduwage K. et al. recorded of a rare occasion of observing this snake on a shrub up to about 60cm above the forest floor. Furthermore according to them Lowland Hump-nosed Pit Viper is absent in anthropogenic habitats. Above specimen was photographed on a banana shrub - considerable height above the ground- But habitat can't be considered as a primary forest though entirely not a home garden ( 6°22'24.18"N,  80°27'8.22"E). Location -though sort of anthopogenic habitat- is very close to the Gin river as well as Sinharaja forest.
