![]() ![]() The boa constrictor is a large snake, although it is only modestly sized in comparison to other large snakes, such as the reticulated python, Burmese python, or the occasionally sympatric green anaconda, and can reach lengths from 3 to 13 ft (0.91 to 3.96 m) depending on the locality and the availability of suitable prey. melanogaster Langhammer, 1983: a nomen dubium ĭescription Size and weight Several other subspecies have been described at different times, but currently, these are no longer considered to be valid subspecies by many herpetologists and taxonomists. The subspecific name ortonii is in honor of American naturalist James Orton. South America except for the ranges of the other three subspecies Boa imperator, Boa nebulosa, Boa orophias and Boa sigma have all been elevated to full species status. Some appear to be based more on location rather than on biological differences. Several subspecies of Boa constrictor have been described in the past, but many of these are poorly differentiated, and further research may redefine many of them. Other common names include chij-chan ( Mayan), jiboia ( Latin American), and macajuel ( Trinidadian). Within the exotic pet trade, it is also known as a "BCC", an abbreviation of its scientific name, to distinguish it from other boa species, such as Boa imperator or "BCI." Īll 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 the species Boa constrictor and Boa imperator. Only one other vertebrate animal shares this trait, the theropod dinosaur Tyrannosaurus rex. Though all boids are constrictors, only this species is properly referred to as the "boa constrictor" - an instance of an animal having the same English common name and scientific binomial. This article focuses on the species Boa constrictor as a whole, and on the nominate subspecies B. ![]() A staple of private collections and public displays, its color pattern is highly variable yet distinctive. The species is native to tropical South America. The boa constrictor is a member of the family Boidae. The Constrictor Knot is normally tied in twine or other small diameter line.The boa constrictor (scientific name also Boa constrictor), also known as the red-tailed boa, is a species of large, non-venomous, heavy-bodied snake that is frequently kept and bred in captivity. Rope Size: The pictures here show the rope tied in large diameter rope. When this is necessary, the binding strand should be cut over the other constrictor strands, using them to protect your rope. Release: The Constrictor Knot can be very hard to undo – cutting the knot can be the only option. However, when the rope has to be first passed around an object, e.g., to hold large objects together while glue sets, the only option may be to Thread the End around the object.ĭisadvantages: The Constrictor Knot fails when tied against a flat surface – it requires a curved surface for the binding turn to grip the Half Hitch. Why use Threading the End: The Twisting Method may be ideal for short lengths when you can “drop” the finished Constrictor Knot over the object. Moreover, if damage did wreck one constrictor, several would remain.Īlternatives: In addition to Threading the End, the Constrictor Knot can be tied by the Twisting Method and the Folding Method. His testing suggests the whipping to be virtually indestructible. When complete he cuts the ends, burns them, and pushes them (with something inert) against the knot so they cannot pull through. ![]() Pulled tight they bite into the rope and narrow it. He describes tying a series of Constrictor Knotss, starting near the free end and working up towards the standing end. It securely ties the neck of a sack or bag it has been used as a temporary hose clamp and it can used to hold items together for gluing.Ĭonstrictor Whipping: I am indebted to John Robinson for the following excellent idea. It is an excellent quick temporary whipping for a fraying rope’s end and can be used to keep a rope’s end together while it is being whipped. Uses: The Constrictor Knot ( ABOK # 1188, p 216.) deserves to be much more widely known and used.
