Dog-faced Water Snake

The Dog-faced Water Snake is a semi-aquatic, mildly venomous snake found in coastal and mangrove habitats across India. Named for its somewhat dog-like facial appearance, this snake has upward-facing nostrils and eyes positioned on the top of its head — adaptations for an aquatic lifestyle.

This rear-fanged snake has mild venom that is not dangerous to humans. It feeds primarily on fish, crabs, and shrimp, hunting in shallow coastal waters, mangrove creeks, and estuaries.

Dog-faced Water Snakes are primarily nocturnal and can be found in brackish water habitats along India's coastline. They give birth to live young (8-26 per litter). The species is an important predator in mangrove ecosystems and helps maintain the ecological balance of coastal environments.
