The Solomon Island Tree Boa (Candoia bibroni australis) is a fascinating serpent found not only throughout the Solomon Islands but also on several nearby eastern Indonesian islands. These boas are known for their extraordinary variability in appearance and color. While most Solomon Island Tree Boas exhibit a faint banded or blotched pattern, some specimens are strikingly vibrant, displaying solid hues of red, orange, or yellow. An exceptional characteristic of this subspecies is its ability to change color, with individuals capable of dramatically darkening or lightening within minutes. This remarkable trait remains not fully understood, adding an element of mystery to their biology. Despite their unique appeal they are rarely exported, unlike the more commonly traded Candoia paulsoni, although both are relatively common in their native habitats, and their market prices are similar.

The Solomon Island Tree Boa (Candoia bibroni australis) is semi-arboreal, thriving in environments that offer both climbing opportunities and ground cover. They require enclosures with sturdy branches to support their climbing habits and a large water bowl to meet their hydration needs. These boas are generally calm and deliberate in their movements, making them more manageable for experienced keepers, though there are occasional individuals with more defensive temperaments. Adult sizes vary significantly between sexes; males typically reach lengths of 3 to 4 feet, while females can grow substantially larger, with some reaching nearly 7 feet. However, the average size for most individuals ranges from 3 to 5 feet. In captivity, they readily accept rodents or chicks as prey, demonstrating their adaptability and versatility as feeders. These unique characteristics and behaviors make Solomon Island Tree Boa a distinctive and intriguing species among tree boas.
