Their scales feel keeled, meaning they have a ridge down the center, giving them a rough texture!

They are often mistaken for venomous cottonmouths, but they have round pupils, not slit pupils.

Special abilities

Diamondback Watersnakes can swim with incredible speed and grace, propelling themselves through water using their muscular bodies to catch slippery prey.

Diamondback Watersnakes have musk glands that help them release a foul-smelling liquid when threatened, making predators think twice about eating them.
