A staple of private collections and public displays, its color pattern is highly variable yet distinctive. Unconsciousness and death likely result from shutting off vital blood flow to the heart and brain, rather than suffocation as was previously believed; constriction can interfere with blood flow and overwhelm the prey's usual blood pressure and circulation. [32] They generally breed in the dry seasonbetween April and Augustand are polygynous; thus, males may mate with multiple females. Fertilization is internal, and the gestation period varies depending on the local temperature. [39], Up to 41.5% of captive boas test positive for eosinophilic inclusion bodies.[42].
