Northern Diamond-Backed Watersnake

Northern Diamond-Backed Watersnake

Nerodia rhombifer rhombifer
Description: 

Of the seven types of watersnakes native to Missouri, the diamond-backed is the largest. The common name is derived from the light areas along the snake's back, which may be shaped like diamonds. The overall color may be light brown or dull yellow, with dark brown markings on the sides and back. Two rows of dark brown half-moons border the yellow belly. Scales along the body have keels, which cause watersnakes to feel rough.

Size: 
Length ranges from 30 to 48 inches (76-122 cm).
Habitat and conservation: 
These snakes may live along slow-moving rivers but more commonly are seen along river sloughs, oxbow lakes and swamps.
Foods: 
Diamond-backed watersnakes eat slow-moving or dead fish, frogs and toads.
Distribution in Missouri: 
Absent from the Ozarks; common in the southeastern corner and over northern and western Missouri. It does not occur in our extreme northern counties.
