Description

The

of the genus ''Candoia'' typically have a rounded and heavy body, with a flattened triangular-shaped head, and an upturned nose. Colors and patterns vary greatly, but most are various shades of brown to black. Species can vary in adult size from to in total length (including the tail). Males are typically smaller than females and can be distinguished by their prominent cloacal spurs.

Behavior

All species of ''Candoia'' are primarily nocturnal.

Feeding

The primary diet of ''Candoia'' species consists of frogs and lizards.

Reproduction

In the snakes of the genus ''Candoia'', breeding occurs early in the year, typically after rains. Several males will approach and pursue a single female, though, there is no combat between the males. Females seem to only

once every two or three years and give birth to litters averaging 10 or so neonates. The Solomon Island ground boa ('' C. paulsoni'') is an exception, as it is known to have particularly large litters, occasionally producing 30 or 40 small neonates.

Captivity

Snakes of the genus ''Candoia'' are frequently imported for the exotic pet trade, but are now being bred in captivity with some regularity by private individuals. Their small size and ease of care make them interesting captives, but wild-caught specimens are not known to acclimate well. The stress of captivity manifests itself in the form of lack of interest in food. Their natural diet often presents a problem for hobbyists mainly familiar with using rodents as food.

Classification

The genus ''Candoia'' is traditionally placed in the subfamily

Boinae The Boinae are a purported subfamily of boas found in Central and South America as well as the West Indies. In the Integrated Taxonomic Information System (ITIS), the ''Boinae'' are considered an invalid synonym of Boidae. Genera ''*) Not ...

; however, a 2013 study comparing DNA sequences of 12 genes of over 4,000 species supported ''Candoia'' as more distantly related, with remaining members of the Boinae being more closely related to the boid subfamily

Erycinae The Erycinae, known as the Old World sand boas, are a subfamily of nonvenomous snakes in the family Boidae. Species of the subfamily Erycinae are found in Europe, Asia Minor, Africa, Arabia, central and southwestern Asia, India, Sri Lanka, and ...

; thus ''Candoia'' was placed in the newly named subfamily Candoiinae.
