Common Bridal Snake (Dryocalamus nympha) is a species of snake found in southern India and Sri Lanka. The yellow mark on the back of the head suggests a bridal veil.

Characteristics: A small snake with a glossy black or dark brown colouration. Its colouration may be accompanied by a series of irregular white or grey stripes. Its ventral area is creamy yellow. This snake has considerably large eyes with vertical pupils which are adaptations for its nocturnal lifestyle. It has a rounded snout and an oval shaped flat head.


A nocturnal snake which is very active and timid by nature. If cornered and provoked it will fiercely attack its challenger repeatedly. This snake has a tendency to enter human dwellings in search of prey. It is highly capable of climbing walls but has an equal tendency to fall off, often onto unsuspecting human occupants with catastrophic results. Feeds mainly on lizards but may consume frogs and other small fauna when the opportunity provides so. Very little known due to the paucity of specimens. It is assumed to be oviparous. Little known about its growth rate. The longest specimens seldom exceed 50 cm.
