The rainbow boa is a species of constrictor snake native to South America and Central America. Numerous subspecies exist, each determined by its geographical range -- for example, Colombian rainbow or Brazilian rainbow boa -- although debate surrounds just how many subspecies exist, as many rainbow boa populations straddle national borders and have interbred, making geographical-based distinctions difficult.

Iridescent Skin
-
The defining characteristic of all rainbow boas is the iridescent skin. This is common throughout the species and is just as visible in Colombian specimens as it is in specimens from Brazil or Guayana. The iridescence is created by microscopic ridges on the scales. These scales act as light prisms. When the light hits the scales, they reflect a rainbow of colors depending on the angle at which the light lands.
Distribution, Range and Habitat
-
Despite his name, the Colombian rainbow isn̵7;t strictly native to Colombia. Specimens have been found in northern parts of South America, such as Panama and Venezuela. They are most commonly found in the Amazonian areas of Colombia. Colombian rainbow boas typically inhabit semi-arboreal habitats as youngsters, but due to the size and weight of adults, they tend toward a terrestrial existence when older, as their tree climbing capabilities diminish.
Size and Appearance
-
Colombian rainbow boas typically reach an adult length of between 4 and 5 feet, with some achieving a length of 6 feet. They are smaller than the Brazilian rainbow boas, which typically grow to around 7 feet in length. Colombian rainbow boas have a brown coloration, which is darker and duller than the more eye-catching Brazilian. The contrast between bands and base color is less obvious in Colombians too.
Habits and Behavior
-
Like all other rainbow boas, the Colombian is nocturnal. They live relatively sedentary lives, only springing into action when a hunting opportunity presents itself. In the wild, the Colombian rainbow boa typically feeds on small birds, small mammals such as mice and rats, and occasionally on small amphibians such as frogs and toads. They kill their food by constricting it with their powerful and muscular body.
Docile Pets
-
Colombian rainbows are popular pets as they̵7;re the most docile of all rainbow boa subspecies. They tolerate handling much better than other species, but experienced handlers may still favor the Brazilian subspecies due to its more eye-catching appearance. Juvenile Colombian rainbow boas may nip when being handled, but with regular handling, adults will lose this inclination.
