Banded Water snake

The banded water snake or southern water snake (Nerodia fasciata) is a species of mostly aquatic, nonvenomous, colubrid snakes endemic to the Midwest and Southeastern United States.
N. fasciata is natively found from Indiana, south to Louisiana, and east to Florida.
In 1992, its congener Nerodia sipedon (northern or common water snake) and it were found in three sites in California by the US Fish and Wildlife Service (USFWS). In 2009, more than 300 banded water snakes were caught in suburbs of Los Angeles by the Nerodia Working Group of USFWS. Then in May 2016, the species was found in the Colorado River basin near Yuma, Arizona. Further trapping did indeed catch large numbers of them, indicating that a thriving invasive population exists in that area.
Adults of the banded water snake measure from 61.0 to 107 cm (24.0 to 42.1 in) in total length, with a record size (in the Florida subspecies) of 158.8 cm (62.5 in) in total length. In one study, the average body mass of adult banded water snakes was 464.3 g (16.38 oz).
It is typically gray, greenish-gray, or brown in color, with dark crossbanding. Many specimens are so dark in color that their patterning is barely discernible. They have flat heads, and are fairly heavy-bodied. If irritated, they release a foul-smelling musk to deter predators.
Their appearance leads them to be frequently mistaken for other snakes with which they share a habitat, including the less common, venomous cottonmouth.
