[16] The size of the prey item increases as it ages. Boa imperator. Our baby dwarf boas for sale are healthy proven feeders that make great pet snakes as they do not get too large. [citation needed] Copulation can last from a few minutes to several hours and may occur several times over a few week period. While not as small as the dwarf insular island populations, adults are still smaller than the larger B. c. constrictor. The young are independent at birth and grow rapidly for the first few years, shedding regularly (once every one to two months). Montgomery, C.E. The coloring of boa constrictors can vary greatly depending on the locality. [21] They generally breed in the dry season—between April and August—and are polygynous; thus, males may mate with multiple females. The coloring works as a very effective camouflage in the jungles and forests of its natural range. Anerythristic Boas are lacking all red pigment. Snake Species of the World: A Taxonomic and Geographic Reference, vol. Currently Boa populations, such as the Hog Island Boa, are currently classified as different 'locales' of Boa Constrictor Imperator. [8], One population is found on the Cayos Cochinos (Hog Islands) off the northern shore of Honduras. [citation needed]. ", Other common names include chij-chan (Mayan),[4] jiboia (Latin American), and macajuel (Trinidadian). 1. Boa imperator, like most Boa species, has a varied diet that consists mainly of rodents, birds, lizards and frogs. ), All subspecies are referred to as "boa constrictors," and are part of a diverse group of New World boas referred to as "red-tailed" boas, comprising species of both boa constrictor and boa constrictor imperator. Today, most captive boa constrictors are captive-bred, but between 1977 and 1983, 113,000 live boa constrictors were imported into the United States. This coloring gives B. constrictor species the common name of "red-tailed boas." [35], Seven subspecies of Boa c. constrictor have been described, but many of these are poorly differentiated and further research may redefine many of them. Boa Constrictor Has Virgin Birth". Their bite can be painful, especially from large snakes, but is rarely dangerous to humans. Most populations, though, are not under threat of immediate extinction; thus, they are within Appendix II rather than Appendix I. 511 pp. Specimens from Central America are more irascible, hissing loudly and striking repeatedly when disturbed, while those from South America tame down more readily. The color of the tail may vary from salmon-pink to orange. [18] The litter size varies between females but can be between 10 and 65 young, with an average of 25, although some of the young may be stillborn or unfertilized eggs known as "slugs". The type locality given is "l'Amerique meridionale, principalement au Mexique" (Central America, principally Mexico).[2]. Some individuals exhibit pigmentary disorders, such as albinism. The size of a mature female Nicaraguan boa is 1.1 m and 1.9 kg, while the larger female B. c. constrictor is not mature until she reaches 1.6 m and 4.5 kg. Boa imperator is commonly confused with other Boa species, such as Boa constrictor. In the pet trade, Nicaraguan Boas have been line bred in order to bring out their naturally light coloration, further reducing the black pigmentation. After this, the snake may not eat for a week to several months, due to its slow metabolism. Current Biology. [14] During breeding, the male curls his tail around the female's and the hemipenes (or male reproductive organs) are inserted. There is a debate that the Boa Constrictor Imperator represents a separate species. This would allow some of the different 'locales' to be reclassified as sub-species of the newly formed Boa Imperator species. 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. [16], Boa imperator is one of the most common snakes kept in captivity; this is mainly due to their calm dispositions, impressive size potential and variety of color and pattern choices. Boa imperator has 55-79 dorsal scales, 225-253 ventral scales, 47-69 subcaudal scales, 18-22 supralabial scales and 1-2 anal scales. [28] At this point, they shed less frequently, about every 2–4 months. The normal or “Wild type” color, typical of most imperator, and “Hypo” color variant. Boa imperator generally live on their own, and do not interact with any other snakes unless they want to mate.
