This photograph depicted a superior view of a potential cottonmouth mimic, the southern water snake, Nerodia fasciata
. This image was used in a visual comparison with three species of cottonmouths, the eastern cottonmouth Agkistrodon p. piscivorus
, (PHIL# 8125), the Florida cottonmouth Agkistrodon p. conanti
, (PHIL# 8126), and the western cottonmouth Agkistrodon p. leucostoma
, (PHIL # 8124).
N. fasciata is a snake whose habitat includes hurricane-prone regions of the United States, which is of importance to those who either live in these regions, or who might be deployed to such areas as a first-responder offering aid to those affected by such a disaster.
