Description

Size

They grow up to 4-6 feet in length. Adult females are noticeably longer and broader than males.

Color and Appearance

Its beautiful iridescent color is this soft-skinned snake’s most striking physical feature. Though there are color variations between subspecies, they all have tiny ridges covering their scales that work as tiny prisms to refract light – hence the rainbow sheen.

These snakes are basically brown, with or without a reddish hue. The head is wider than their neck, with three black stripes on the top. The neck and dorsal side of the body is covered with black rings with reddish or orange markings.
Adult males have rather noticeable spurs on either side of their anal vent.

Are they Dangerous

Like most other boas, these non-venomous snakes do not pose any serious threat to humans. However, they have sharp hooked teeth for tightly gripping their prey, so they can inflict a rather painful bite and even draw blood. But since they are relatively docile, they would not get aggressive unless cornered or mishandled.

Bites are more common when handling or training a new pet rainbow boa.

Distribution

From lower Central America to South America, in Costa Rica and Panama, as well as the Amazon River basin, French Guiana, coastal Guyana, southern Venezuela, and Suriname, down to northern Argentina

Habitat

Primarily terrestrial, they prefer hot and humid woodlands and forests but can also be found in savannas.

They like to climb up large bushes and trees mainly to rest. Often acknowledged as good swimmers, they may also spend time in waterbodies.

Lifespan

Up to 20-30 years with proper care

Diet

Rodents, birds, lizards, and some aquatic animals; In captivity, they can eat frozen mice.

These snakes are constrictors and are semi-arboreal, preferring to hunt on the forest floor.

Predators

Birds of prey and certain small carnivores

Reproduction

Gives birth to live young (Ovoviviparous)

The snakes reach sexual maturity between 2.5 and 4 years when the males are about 4 feet (1.2 meters) long, and the females are about 4.5 feet (1.4 meters). The males mate with multiple females during their breeding season between November and January. Rainbow boas have a rather long gestation period of around 5 months, after which they give birth to 12-25 hatchlings, about 15-20 inches long.

Care Sheet

Temperament

Docile and occasionally aggressive; need to get used to regular handling

Size of the Enclosure

For younger snakes (up to 2 feet), a 10-20 gallon tank would be enough. Adult snakes need more space, so a 48” x24” x24” enclosure would be ideal.

Substrate

Good quality reptile mulch like coconut husk, cypress mulch, and wood shavings.

Humidity

Around 95% for juveniles; 75-90% for adults

Temperature

70-75°F during the night; 80-85°F during daytime

Lighting

They do not require special UV lighting. A 40W spotlight can be used for the hot spot in the tank, but since these boas do not like to bask, the light need not be left on for long.

FAQs

Q. Do Brazilian rainbow boas make good pets for beginners?

Ans. They are not suitable for people with no experience in taking care of snakes and reptiles, because these snakes need careful and frequent handling before they can get used to their owner. They can even get pretty aggressive during the initial stage of taming them.
