Currently, this species is listed by the IUCN as an animal of “least concern,” indicating that population numbers are stable at this time. They can be easily recognized due to their smooth dorsal scales, iridescent shine, as well as their amethyst-like coloration (hence their name). Endemic to Indonesia, Papua New Guinea, and Australia, the amethystine python is an incredibly large species renowned for its size, coloration, and weight. The amethystine python (sometimes referred to as the “scrub python,” or “sanca permata”) is a species of large, non-venomous snake from the Pythonidae family. Conservation Status: “Least Concern” (Population Stable).Geographical Range: Indonesia, Papua New Guinea, and Australia.Massive amethystine python coiled around a tree branch. For these reasons, they were an easy choice for this list as they dwarf most snake species known to currently exist worldwide. In regard to world records, the longest boa constrictor ever discovered was over 14.6-feet in length. Likewise, they are a relatively heavy snake, reaching 60 to 100 pounds at maturity. Nevertheless, the largest of boa constrictors typically maintain an average length of approximately 7 to 12 feet in length. The overall size of the boa constrictor is heavily dependent upon species, locale, and environmental conditions. Birds (such as eagles and hawks) may also pose an issue for newborns. During their adolescent stages, however, caiman and alligator pose the largest threat to this particular species. To date, few (if any) natural predators exist against the boa constrictor when fully grown. These include small to medium-sized mammals and birds, along with large lizards, ocelots, bats, and frogs. Within their natural habitats in the wild, the boa constrictor is afforded a wide-array of animals to prey upon.

As of 2021, the IUCN has listed nearly all species (and subspecies) of the boa constrictor as “near threatened” with population numbers suffering a significant decline over the past few decades. Colors vary significantly with this species and are usually dependent upon the boa constrictor’s natural habitat.

Apart from their incredible length (and heavy appearance), the animal can be easily identified by their brown or reddish “saddles” that adorn their skin, as well as their pointed snouts. Endemic to the tropical regions of South America (as well as parts of the Caribbean), the boa constrictor is an incredibly large animal that has become a staple of pet-enthusiasts and zoos. The boa constrictor (also known as the “red-tailed boa,” or “common boa”) is a species of large (non-venomous) snake from the Boidae family.

Geographical Range: Tropical Regions of South America.Large boa constrictor on display at a local zoo. As of October 2021, the Cuban boa is currently listed by the IUCN as a “near threatened” species, with overall population numbers declining each year. A particular favorite of the Cuban boa, however, is the Hutia, a large rodent that is similar to a beaver in its appearance and overall size. Potential prey for this animal includes a variety of mice, rats, and larger mammals. As a constrictor species, the Cuban boa actively seeks out its prey within its natural habitat, ambushing, then constricting its victims before consumption of their meal. Endemic to Cuba and its adjacent islands, this large species is found predominantly in the region’s tropical forests where prey is both abundant and easy to find. The Cuban boa (also known as the “Cuban tree boa”) is an incredibly large snake from the Boidae family. Conservation Status: “Near Threatened” (Population in Decline).Geographical Range: Cuba and Surrounding Islands.
