Diamondback Water Snake: 21 Facts You Won't Believe!

Diamondback water snake facts illustrate their habitat, population, and physical characteristics.

The diamondback water snake (Nerodia rhombifer) or diamond-backed watersnake is a medium-sized species of large non-venomous snake in the central United States and northern Mexico. It is the most widely distributed species of snakes within its range, found on every continent except for Antarctica.

Diamondback water snakes can be found in aquatic habitats such as lakes, ponds, marshes, swamps, rivers, streams, creeks, and ditches. Unlike other water snake species that lay eggs on land or near the surface of the water where they live, diamondback water snakes typically lay eggs in shallow wetlands more than 35 ft (10.7 m) from the shoreline. They are very commonly seen along the banks of the Mississippi River. These water snakes are not considered dangerous as they are not poisonous.

Diamondback water snakes are not a common species, but they are found in many eastern states, including Florida, New York, and Texas. The diamondback water snake also lives in parts of the north and west coast of the United States. These snakes can grow 30-48 in (76-122 cm) long and have a yellowish-brown color, with dark diamonds and stripes running down their back. They have a dark diamond-shaped pattern down their back that can be distinguished by black lines or dark blotches on either side.
