About the Wagler's Snake

Xenodon merremii, also known commonly as Wagler's snake, is a species of snake in the subfamily Dipsadinae of the family Colubridae. The species is endemic to South America and is widespread in the eastern half of the continent.

Xenodon merremii occurs in Venezuela, Guyana, Suriname, French Guiana, Brazil, Bolivia, Paraguay, Uruguay, and northern Argentina. The preferred natural habitat of Xenodon merremii is open areas of savanna and shrubland, at elevations from sea level to 2,000 m (6,600 ft), but it is also common in disturbed habitats.

The specific name, merremii, is in honor of German herpetologist Blasius Merrem. Adults of Xenodon merremii are usually 1 m (39 in) or less in total length (tail included). Its color pattern is very variable. Some "red phase" specimens are a uniform reddish tan. Other specimens are pale brown dorsally, with broad dark-brown crossbands, which are edged with black, and are narrower or interrupted in the middle. The latter color pattern resembles that of the venomous snake Bothrops alternatus.

Xenodon merremii preys on insects, frogs, toads, lizards, and sometimes snakes... Wikipedia →
