Distribution and habitat
The species is endemic to Western Ghats mountains, occurring along the southern and western India at 600–2,000 metres (2,000–6,600 ft) elevation. The type locality is the Western Ghats of southwestern India. Records of this species are from Slient valley, western Nilgiris, Wayanad, Coorg, Malnad region of Karnataka, Castle Rock, Goa and northwards into Maharashtra in the Amboli hills. Kolhapur area. It inhabits riparian forests and is very partial to hill streams and torrents, situated within dense wet rainforests, sometimes also evergreen and deciduous forests, where it may be found on the ground, on rocks present in stream beds, on low vegetation, or in shrubs.
Ecology
The Malabar pit viper is nocturnal and usually inactive in the day, sometimes seen basking on rocks or trees near streams. It is more commonly encountered during the monsoon months. The species preys upon frogs, lizards, nestling birds, musk shrews, mice and other small animals.
Venom
C. malabaricus is slow-moving, but capable of fast strikes. Its venom causes moderate pain and swelling to humans. These symptoms subside in a day or two.
