    Peruvian redtail boa (Boa c. constrictor)


    Peruvian redtail boas had been misnamed as "ortonii" subspecies of Boa constrictor for a long time. Nowadays, it is obvious that animals from Eastern Peruvian rainforests belong to Boa c. constrictor.

    However, Peruvian populations of Boa c. constrictor are distinct and differ from other Boa c. constrictor populations in appearance. Animals have yellow, maybe golden-yellow basic tone. The tail is redish, but not as bright as boas' from Suriname or Guyana, it is much rather orange colored.

    Saddle patterns- that have a number of 15-19 -are usually hourglass shapped (widow peaks rarely occur) and tend to become darker and darker by age. Finally, adult animals will have almost black dorsal patterns. It is also known that some adults take jet black overall, especially during the gravidity.

    Peruvian redtail boas are certainly one of the biggest members of not just the subspecies, but the species, as well. Biggest females could reach 3 m (more than 10 ft) and 30 kg (66 lbs). Interestingly, despite female's large body, number of babies are rarely more than 20, although those litters may contain huge, sometimes even 0,6 m (2 ft) long babies that would hardly be imagineable with other localities.

    In contrast with Suriname and Guyanan redtails, Peruvians regurgitate only in exceptional cases and mostly due to improper feeding. Temper of specimens varies from totally peaceful, calm to unmanageable, thus adults should always be handled with much respect by keepers.


    Peruvian redtail imported from Iquitos

    Peruvian boas in captivity are originally from two locations, Iquitos and Pucallpa. The latter one is somewhat smaller and harder to obtain than its relative from Iquitos.
    I must emphasize however that the "different look" between Iquitos and Pucallpa boas in captive these days are due to selective breeding and originally these two localities look almost the same in terms of morphology in the wild.
