The Boidae, commonly known as boas or boids, are a family of nonvenomous snakes primarily found in the Americas, as well as Africa, Europe, Asia, and some Pacific islands. Boas include some of the world's largest snakes, with the green anaconda of South America being the heaviest and second-longest snake known; in general, adults are medium to large in size, with females usually larger than the males. Six subfamilies comprising 15 genera and 54 species are currently recognized.
Aspidites is a genus of pythons endemic to Australia. The name can be translated as "shield bearer" and pertains to the symmetrically shaped head scales. Currently, two species are recognized.
Liasis is a genus of pythons found in Indonesia, New Guinea and Australia. Currently, three extant species are recognized and one giant fossil species L. dubudingala, estimated to have been around 10 m (33 ft) in length.
Xenopeltis, the sunbeam snakes, are the sole genus of the monotypic family Xenopeltidae, the species of which are found in Southeast Asia. Sunbeam snakes are known for their highly iridescent scales. Three species are recognized, each one with no subspecies. Studies of DNA suggest that the xenopeltids are most closely related to the Mexican burrowing python and to the true pythons (Pythonidae).
Children's python is a species of nonvenomous snake in the family Pythonidae. The species is named after John George Children. It is a nocturnal species occurring in the northern half of Australia and generally found on the ground, although it often climbs trees. Usually growing to about 1.0 m (3 ft) in length or more depending on the polymorphic variant, it is typically a reddish-brown colour, darker on the upper surface, and with many darker blotches, especially on younger specimens. The Stimson's python variant has much stronger and more variable colours; often being adorned with reddish-brown to chocolate blotches against lighter tan. It feeds mostly on small mammals and birds, and as with other pythons, it constricts its prey before swallowing it whole. It is a popular pet among reptile enthusiasts.
The woma python, also known commonly as Ramsay's python, the sand python, and simply the woma, is a species of snake in the family Pythonidae, endemic to Australia. Once common throughout Western Australia, it has become critically endangered in some regions.
The black-headed python is a species of snake in the Pythonidae. The species is endemic to Australia. No subspecies are currently recognized.
Apodora papuana is a species of python, commonly known as the Papuan python, Irian python or Papuan olive python. It is found in New Guinea. It is the only species in the genus Apodora. No subspecies are currently recognized.
The amethystine python, also known as the scrub python or sanca permata in Indonesian, is a species of non-venomous snake in the family Pythonidae. The species is found in Indonesia and Papua New Guinea. Popular among reptile enthusiasts, and noted for its coloration and size, it is one of the largest snakes in the world, as measured either by length or weight, and is the largest native snake in Papua New Guinea. Until 2000, the larger S. kinghorni was generally considered a subspecies of S. amethistina, and this change of classification has still not been universally reflected in literature. Because of this issue, S. amethistina has often been described as the largest snake in Australia, but this is not accurate since under the current classification, this species does not occur in Australia.
The rough-scaled python is a large-scaled python species endemic to Australia. No subspecies are currently recognized.
The Cuban boa, also known as the Cuban tree boa and by locals as maja de Santa María, is a very large species of snake in the family Boidae. With lengths exceeding 5 m (16 ft) and a relatively heavy build, the Cuban boa is one of the largest snakes in the world. The species is native to Cuba and some nearby islands. No subspecies are currently recognized.
Python brongersmai is a species of nonvenomous snake in the family Pythonidae. The species is native to Southeast Asia.
Morelia spilota spilota is a subspecies of carpet python, popularly known as the diamond python. It is a medium to large snake, found in coastal areas and adjacent ranges of south-eastern Australia. It is the most southerly occurring python in the world and is found at higher altitudes than any other species of Australian python.
The Timor python is a python species found in Southeast Asia. A dwarf species, no subspecies are recognized as being valid. Like all pythons, it is a nonvenomous constrictor; unlike larger species such as the reticulated python, it is not considered dangerous to humans.
The water python is a python species found in Australia and Papua New Guinea. No subspecies are currently recognized. Like all other pythons, it is not venomous.
Liasis mackloti, commonly known as Macklot's python or the freckled python, is a species of python, a non-venomous snake in the family Pythonidae.

Liasis olivaceus barroni is a python found in the Pilbara region of northwest Australia. They are recognised as a subspecies of Liasis olivaceus, separating the population from the olive python found to the east. It is a large snake, most often around 2.5 metres in length, although individuals may attain a larger size. The python is an ambush predator, using a sit and wait method at a path or beneath the water to capture a variety of animals that inhabit the arid surroundings. The range of prey includes amphibians, birds and other reptiles, and mammals as large as a rock wallaby.
The boa constrictor, also known as the common boa, is a species of large, non-venomous, heavy-bodied snake that is frequently kept and bred in captivity. The boa constrictor is a member of the family Boidae. The species is native to tropical South America. A staple of private collections and public displays, its color pattern is highly variable yet distinctive. Four subspecies are recognized. This article focuses on the species Boa constrictor as a whole, and on the nominate subspecies B. c. constrictor.
D'Albertis' python, also known commonly as D'Albert's water python or the northern white-lipped python, is a species of python, a non-venomous snake in the family Pythonidae. The species is endemic to New Guinea. There are no subspecies that are recognized as being valid.
