Doliatus

Doliatus is a genus of small to medium-sized snakes belonging to the family Colubridae. The genus is native to the Americas, with species found in Mexico, Central America, and South America. The name "Doliatus" is derived from the Greek word "dolios," meaning "barrel," referring to the distinctive, barrel-shaped scales found on the sides of these snakes.

The genus Doliatus is characterized by its smooth, scaleless body, which is a unique feature among colubrids. The scales on the sides of the body are enlarged and keeled, giving the snake a distinct appearance. The head is typically broad and flattened, with a pair of small, round eyes and a short, pointed snout. The coloration of Doliatus species varies, but many have a pattern of dark blotches or bands on a lighter background.

Doliatus snakes are primarily terrestrial and inhabit a variety of habitats, including forests, grasslands, and deserts. They are generally non-venomous and feed on small vertebrates such as lizards, frogs, and rodents. Reproduction in Doliatus species is oviparous, with females laying a clutch of eggs.

The genus Doliatus includes several species, with the most well-known being Doliatus incilis, commonly known as the Mexican Doliatus. This species is found in Mexico and Central America and is known for its distinctive coloration and behavior. Doliatus snakes are generally docile and are not considered a threat to humans, although they may bite if provoked or cornered.
