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.

Thelytoky is a type of parthenogenesis and is the absence of mating and subsequent production of all female diploid offspring as for example in aphids. Thelytokous parthenogenesis is rare among animals and reported in about 1,500 species, about 1 in 1000 of described animal species, according to a 1984 study. It is more common in invertebrates, like arthropods, but it can occur in vertebrates, including salamanders, fish, and reptiles such as some whiptail lizards.

Titanoboa is an extinct genus of giant boid snake that lived during the middle and late Paleocene. Titanoboa was first discovered in the early 2000s by the Smithsonian Tropical Research Institute who, along with students from the University of Florida, recovered 186 fossils of Titanoboa from La Guajira in northeastern Colombia. It was named and described in 2009 as Titanoboa cerrejonensis, the largest snake ever found. It was originally known only from thoracic vertebrae and ribs, but later expeditions collected parts of the skull and teeth. Titanoboa is in the subfamily Boinae, being most closely related to other extant boines from Madagascar and the Pacific.
Chilabothrus chrysogaster, commonly known as the Turks and Caicos Islands boa or the Southern Bahamas boa, is a species of snake found in the Southern Bahamas and the Turks and Caicos Islands. Local names include the rainbow boa, the Bahamas cat boa, the rainbow snake, and the fowl snake. Like all boids, it is not a venomous species.
The Bahamian pygmy boa constrictor, also known as the Inagua trope or Bahama wood snake, is a species of nonvenomous snake in the family Tropidophiidae. The species is endemic to Great Inagua Island in the Bahamas.

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.
Boa constrictor occidentalis, also commonly known as the Argentine boa, is a subspecies of large, heavy-bodied, nonvenomous, constricting snake. Boa constrictor occidentalis is a member of the family Boidae, found in the subtropical temperate west of Argentina and Paraguay, although some members have been reported to exist in Bolivia as well.
