The Hump-nosed Pit Viper, scientifically known as Hypnale hypnale, is a venomous snake found in South Asia. These snakes belong to the Viperidae family and are characterized by their distinctive hump on the nose and their potent venom. In this article, we will discuss various aspects of Hump-nosed Pit Vipers in detail. Hump-nosed Pit Vipers are small to medium-sized snakes, with adults measuring around 40-70 cm in length. The body is stout and cylindrical, with a short tail. The head is triangular, and the eyes are small with vertical pupils. The hump on the nose is a unique feature of this species.
Scalation:
The scales of Hump-nosed Pit Vipers are keeled, meaning they have a raised ridge along the center. They have 21-25 rows of dorsal scales and 147-169 ventral scales. The subcaudal scales are paired, and the anal plate is single.
- They have keeled scales, which means each scale has a raised ridge or keel running along the center.
- They have 21-25 rows of dorsal scales running down their back.
- They have 147-169 ventral scales on their belly.
- They have paired subcaudal scales, meaning two scales on each side of the underside of their tail.
- They have a single anal plate located near the base of their tail.
- These features are common to many species in the Viperidae family, but when combined, they help to identify the Hump-nosed Pit Viper as a distinct species.

Natural History:
Hump-nosed Pit Vipers are nocturnal and are active at night. They are ambush predators, hiding in vegetation or under rocks and waiting for prey to come within range. Their diet includes small rodents, lizards, and frogs.
Habitat:
Hump-nosed Pit Vipers are found in South Asia, including India, Sri Lanka, and parts of Pakistan. They prefer moist environments and can be found in forests, grasslands, and rocky areas.
Behavior:
Hump-nosed Pit Vipers are generally docile and prefer to avoid human contact. When threatened, they may coil and strike, but they are not aggressive unless provoked. They are also known to hiss loudly when threatened.
Reproduction:
Hump-nosed Pit Vipers are oviparous, meaning they lay eggs. The female will lay a clutch of 6-12 eggs in a moist, protected area. The eggs hatch after 50-60 days, and the juveniles are independent from birth.
Location:
Hump-nosed Pit Vipers are found in South Asia, including India, Sri Lanka, and parts of Pakistan.
Venom:
Hump-nosed Pit Vipers are venomous and have potent venom that can cause significant tissue damage and even death in humans. The venom is primarily hemotoxic, meaning it destroys red blood cells and damages blood vessels, leading to swelling, bleeding, and tissue death. The venom also has neurotoxic properties, which can cause paralysis and respiratory failure. The strength of the venom varies depending on the individual snake and the location, but it is considered to be one of the most dangerous venomous snakes in South Asia.
Hump-nosed Pit Vipers are a fascinating species of snake found in South Asia. They are ambush predators and are active at night. Their venom is potent and can cause significant tissue damage and even death in humans. Despite their venomous nature, they are generally docile and prefer to avoid human contact. The hump on their nose is a unique feature that helps to distinguish them from other species of snakes.
