starts withDorsally, it is light brown or yellowish, with 26–35 reddish-brown to black crossbands. Ventrally, it is yellow or white, with reddish-brown or black markings. In large adult individuals, the ground color on the lower sides is sometimes darker than the crossbands, producing an appearance of alternating blotches on the back and sides.
The Florida water snake differs from the southern water snake (N. f. fasciata ) chiefly in the shape of the markings on the ventrals. In N. f.pictiventris, these markings consist of transverse blotches, many of them enclosing an oval white spot, whereas in N. f. fasciata, they are solid, squarish spots.
Adults average 24 to 42 in (61 to 107 cm) in total length.
The Florida banded water snake is endemic throughout Florida and southeastern Georgia. In addition, it has been introduced to Brownsville, Texas. It has also established populations in Folsom and Harbor City, California.
They are ovoviviparous. Mating occurs from March to May, and the young are born from May to August, in broods of 25–57. The newborns are 180–223 mm (7.0–8.8 inches) in total length.
