Pacific Boa

Candoia carinata

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The Pacific boa is a small, variable boa of the islands of the western Pacific, with a prehensile tail that it uses to climb despite its other name, Pacific ground boa. Its presence in the Pacific is a biogeographical puzzle: the boas are an essentially American group, and these islands lie half a world away from their closest relatives.

Fun facts

  • Its presence in the western Pacific is a puzzle: the boas are an essentially American and Malagasy group, and how its ancestors reached New Guinea and the Solomon Islands is still debated between continental drift and dispersal on rafts of vegetation.
  • It is extraordinarily variable: colour and pattern change so much from island to island that numerous subspecies have been described, and several populations may be separate species.
  • It is viviparous and gives birth to up to thirty young after a gestation of more than half a year, without laying eggs.
