The Alien Invasive Species Act does not take this scientific name change into account and has Boa Constrictor subspecies listed as a category 2 invasive species requiring a permit ( please note that Boas will be removed from the list for Gauteng). Enough genes changed to be able to separate them as a species. The separation by the Andes effected the genetics of the Common Boa by genes changing in relation to the selection pressures of a slightly different habitat to the Red Tailed Boa. The True Red Tailed Boas evolved east of the Andes mountains so Common Boas and True Red Tailed Boas are separated by the Andes mountains allowing them to evolve into two different species. The new scientific name for the Common Boa is Boa imperator reflecting that it is a separate species notice that the subspecies name ” constrictor ” is now missing from the name. Due to new genetic evidence the Common Boa has found to be a completley different species from the Red Tailed Boa and are no longer considered a subspecies. The first successful breeding in South Africa of Guyana Red Tailed Boas happened a few weeks ago so they are not commonly bred in South Africa at all. In fact Common Boas can be found as far north as the Sonoran desert in Mexico, whilst Red Tailed Boas are found further south in countries such as Guyana and Surinam where most captive lines of true Red Tailed Boas come from.True Red Tailed Boas have bright red tails whilst Common Boas tend to have brownish or orange tail markings. Only the so called True Red Tailed Boa ( Boa constrictor constrictor) can be called Red Tailed Boas, which live in the Amazon basin and grow much larger than the Common Boas ( Boa constrictor imperator) which are a central American species. There are 8 subspecies of Boa Constrictor with the most commonly available subspecies in the pet trade being Boa Constrictor Imperator. The boa first strikes at the prey, grabbing it with its teeth it then proceeds to constrict the prey until death before consuming it whole.It may come to you as a shock but the Red Tailed Boa you have as a pet, see in a pet store, reptile expo or on an online ad is not actually a Red Tailed Boa to explain this we must look into the taxonomy of Boa Constrictor subspecies. However, they do hunt, particularly in regions with a low concentration of suitable prey, and hunting generally occurs at night. Boa constrictors are ambush predators, so often lie in wait for an appropriate prey to come along, when they attack. It makes their eyes appear milky, blue, or opaque so that the snake cannot see very well, causing it to be more defensive than it might be otherwise.
#Boa imperator vs boa constrictor imperator skin
Like all snakes, Boa constrictors in a shed cycle are more unpredictable, because of the substance that lubricates between the old skin and the new one. Their bite can be painful, especially from large snakes, but is rarely dangerous to humans. These snakes strike when they perceive a threat.
Boa constrictors often occupy the burrows of medium-sized mammals, where they can hide from potential predators. As semi-arboreal snakes, young Boa constrictors may climb into trees and shrubs to forage however, they become mostly terrestrial as they become older and heavier. They are nocturnal, but they may bask during the day when night-time temperatures are too low. Boa constrictors generally live on their own and do not interact with any other snakes unless they want to mate.
