Rainbow boa
Species of snake From Wikipedia, the free encyclopedia
The rainbow boa (Epicrates cenchria) is a boa species endemic to Central and South America. A semi-arboreal species (not only do they climb in the wild but also proven in captivity), it is known for its attractive iridescent/holographic sheen caused by structural coloration. Five subspecies are currently recognized, including the nominate subspecies described here.[3]

Distribution and habitat
The rainbow boa is found in lower Central America (Costa Rica and Panama), and farther south into South America. It occurs east of the Andes, roughly reaching northern Argentina (in the provinces Chaco, Córdoba, Corrientes, Formosa, Salta, Santiago del Estero and Tucumán).
The rainbow boa's habitat generally consists of humid woodlands and rainforests, but it can also be found in open savannas.
Description
The rainbow boa is typically orange, brown, or reddish brown, with a paler belly and black markings: three parallel stripes on the head, rings down the back, and lateral blotches with a crescent over them, although there is a great deal of natural variation that may be heightened by artificial breeding. It is 4 to 6 feet in length[4] and sexually dimorphic, as females are slightly longer and have wider abdomens. Males are stronger when compared with females of the same length and more resistant to handling.[5]
Behavior
Rainbow boas are nocturnal and most active in the middle of the night.
This species is semi-arboreal, spending time both on the ground and in trees. They are also known to spend time in bodies of water, and are considered capable swimmers.
Mating habits
 | This section needs additional citations for verification. (March 2023) |
The rainbow boa reaches sexual maturity at 1.2 meters for males and 1.4 meters for females, or when they're approximately 2.5 to 4 years old.[4] Females need to be the correct size otherwise they could have complications during and after birth. Males can mate with multiple females which can be beneficial for reptile breeding.
Eating habits during breeding season
Males generally go without feeding during the mating season and females tend to eat smaller portions during the breeding season. In order to decrease the probability of birthing issues, females should be fed smaller rats/mice in order to save space for proper ova development.
It is not unusual for both sexes to go without eating during the mating season.
Captivity
The most common type of rainbow boa found in the pet trade is the Brazilian rainbow boa, E. c. cenchria. During the 1980s and early 1990s, substantial numbers were exported from Suriname. Today, however, far fewer are exported, and most offered for sale are captive bred.[6] With good care, a captive Brazilian rainbow boa can be expected to live for up to 30 years, but most live up to 20.[7]

Etymology
The subspecific names barbouri and gaigeae are in honor of American herpetologists Thomas Barbour and Helen Beulah Thompson Gaige, respectively.[8]
