- Common names: Bismark ringed python.
is a monotypic genus
containing the non-venomous python species
, B. boa
, found on the islands of the Bismark Archipelago
. No subspecies
are currently recognized.
Adults grow to a length of 152-183 cm (5-6 feet). The color pattern consists of a series of brilliant orange and black rings in juveniles, but this fades in about a year as the snakes mature. Adults are usually a shade of brown with black rings, or a uniform blackish brown. Usually, there is a light spot behind the eye. Some specimens may have black rings that are irregular, incompletely formed or even absent. The scales are highly iridescent.
Found on the islands of the Bismark Archipelago
, including Umboi
, New Britain
, Gasmata (off the southern coast), Duke of York
and nearby Mioko, New Ireland
and nearby Tatau (off the east coast), the New Hanover Islands
and Nissan Island
. The type locality
given is "Nouvelle Irlande" (New Ireland).
Rain forests in open and/or cultivated areas. Often found in piles of coconut husks.
These snakes are nocturnal and fossorial
Their diet consists primarily of small rodents, for which they actively forage. They have been reported to enter houses and agricultural structures in search of prey. Hatchlings feed on lizards and juvenile rodents.
, they lay up to a dozen eggs that are generally "brooded" by the female, although this is not always the case.
Young specimens will often bite readily, but they usually settle down as they mature to become trustworthy captives. Wild caught animals are not generally available. The species appears to be well-established in captivity with several hundred ringed pythons hatching out from breeder's collections each year. Captive specimens seem to benefit if provided with a box of damp moss in which to occasionally sit. This species likes high humidity but is intolerant of poor ventilation or wet conditions.
