Diamondback Watersnake (Nerodia rhombifer) lives in freshwater swamps across South-central United States. Its conservation status is Least Concern.
Fascinating facts about the Diamondback Watersnake
- When hunting, the diamondback water snake perches on a branch over the water, dips its head, and waits for a fish to swim by, turning the branch into a natural fishing rod. Its bite feels like a tiny harpoon; sharp teeth lock onto slick fish and a slight hemotoxin in the saliva makes wounds bleed longer. Because the snake hisses, flattens its head, and drops into the water at the slightest threat, observers often mistake this defensive display for aggression. That misreading leads many people to confuse it with the venomous cottonmouth that shares the same wetlands, a mistake that fuels unnecessary killings.
- Unlike many snakes that lay eggs, the diamondback water snake gives birth to live young, a trait called ovoviviparity, allowing embryos to develop safely in the mother's body. Newborns emerge at 8-10 in (20-25 cm) long. Remarkably, this species is listed as one of the few snakes known to reproduce asexually.
- Human ignorance poses the biggest danger to the diamondback water snake. People often kill it, mistaking it for the venomous cottonmouth or rattlesnakes, despite the fact that water snakes are far more common than their poisonous cousins in the same areas. This misidentification fuels unnecessary killings.
- Diamondback water snakes average 76-122 cm (30-48 in) and have a record length of 180 cm (69 in). Adult males sport multiple papillae on the chin, tiny tubercles that no other U.S. snake has.
