The false water cobra is a species of rear-fanged venomous snakes located in South American Flood Plains. The false water cobras have other names such as false cobra, South American water cobra, and the Brazilian smooth snake. It is often referred to within the reptile hobby more simply as either a “falsy” or false or an “FWC“, which is an abbreviation of the common name false water cobra. It is a large colubrid that may exceed 3m (9 to 10 ft) in total length (including tail) when adult. However, most false water cobras reach approximately 2 m ( 6 to 7 ft) in total length.
