Their head is a bit wider than the neck and nose is slightly pointed. They have smooth scales, but not shining and the underside is yellowish or white.

Distribution: This species is found in plains throughout most parts of India.

Habitat: Banded Racers are very alert and fast snakes and have a preference for high grass or bushes. Generally they occupy rodent burrows, rock piles and heavy brush.

Habits: They are active and quick during the day. When captured, they may bite and display a thin ‘hood’ by flattening its ribs in the neck region. But after some time, it calms down.

Young: The female lays about 2 to 6 eggs some-time around October.

Food: The young eat frogs and insects, while adults feed on mice and Metad Rats (Ratus maltada). They kill their prey by constricting or pressing with the body.

Status: The population of Banded Racers is getting reduced because of severe over-grazing and clearing of vegetation.

Labels: New Guinea Bockadam, Dog-faced water-snake
Binomial name: Cerberus rynchops
Common name: Dog-faced Water-Snake

Scientific classification

Kingdom:

Animalia

Phylum:

Chordata

Class:

Reptilia

Order:

Squamata

Suborder:

Serpentes

Family:

Colubridae

Genus:

Cerberus

Species:

C. rynchops


Type: HARMLESS

Distinguishing Features: Medium sized; thick-bodied; scales keeled and dull; head wider than neck; eyes small; back pattern unclear and checkered belly is distinct.

Average Length: 60 cm; At Birth: 15 cm; Maximum: 1.25 m (female).

Description: This Water-Snake is heavy-bodied, with their eyes and nostrils set high on the head. Their overall colour is slate-grey, but sometimes with indistinct uneven black cross bars. Their abdomen has distinctive black and white checks. Their scales are dull and heavily keeled. There are in all 6 other species of rear-fanged swamp snakes in India.

Distribution: They are found in near Coastal India including the Andaman and Nicobars.

Habitat: Dog faced water-snakes hang about in muddy and rocky areas in estuaries such as mangrove swamps, salt pans and creeks. Though they prefer brackish water, this water-snake is also found several miles from the coast in fish traps set in rice fields.

Habits: They seem to be nocturnal but mating and feeding activity is also found during the day. They just peep out exposing only their heads from the holes where they live. They have a long sensitive tongue which is extended out as they swim along the bottom. This species of water-snakes are excellent swimmer, when scared they snap to a leaping and escape to the land.

Young: Around 6 to 30 living young are born between February and May.

Food: Being water-snake, they mainly feed on several species of fishes, which includes spiny ones like Tilapia and cat fish. They also eat frogs.

Status: Though this species is unexploited, the loss of coastal habitat and pollution of brackish water badly depletes their number. Once considered a rare snake, actually it is one of the most plentiful in India.

Habitat: They mainly dwell in much wetter areas than the Spectacled Cobra.
