Boas are a type of snake that are members of the Boidae family. For other uses see Boa constrictor (disambiguation Boa constrictor is a non-venomous boa Species found in Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Reptiles, or members of the class Reptilia are air-breathing Cold-blooded Vertebrates that have skin covered in scales as opposed to hair or feathers Squamata (scaled reptiles is the largest recent order of Reptiles including Lizards and Snakes Members of the order are distinguished by A snake is an elongate Reptile of the suborder Serpentes Like all reptiles snakes are covered in scales. John Edward Gray ( 12 February 1800 &ndash 7 March 1875) was a British zoologist.

Common names sand boas Gongylophis is a Genus of non-venomous boas found in mostly in Africa and A snake is an elongate Reptile of the suborder Serpentes Like all reptiles snakes are covered in scales. Boas are basal snakes that are "primitive" in evolutionary terms (i. Henophidia is a Superfamily of the suborder Serpentes ( Snakes that contains boas, pythons and other Snakes Snakes belonging e. less derived). They are constrictors and most give birth to live young. Snakes Constriction is a method used by various Snake Species to kill their prey. They have anal spurs, a pair of claws on each side of the cloaca which assist in mating. Anal spurs are the vestigial remnants of legs found on each side of the vent in primitive Snakes, such as boas and pythons The In zoological anatomy a cloaca is the posterior opening that serves as the only such opening for the intestinal and urinary tracts of certain animal species Boas are named after cows (Latin: bos) because of the old myth that boa snakes pursue cows and suckle them until they are drained to death. Cattle, colloquially referred to as cows, are domesticated Ungulates a member of the Subfamily Bovinae of the family Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome.
Boas have two subfamilies: Boinae or true boas and Erycinae or sand boas. Common names boas The Boinae are a subfamily of non-venomous boas found in Central and South America Common names Old World sand boas The Erycinae are a subfamily of non-venomous boas found in Europe, Asia Pythons are sometimes classified as a subfamily of Boidae, but are frequently listed under their own family, Pythonidae. Common names pythons The Pythonidae are a family of non- Venomous Snakes found in Africa, Asia Sand boas are also frequently listed under their own family, Erycidae.
Boinae subfamiliy
Snakes of the topfamily Boinae are found in North America, New England, Great Britain, and Spain. History See also History of New England New England's earliest inhabitants were Algonquian -speaking Native Americans including the See also Kingdom of Great Britain Great Britain (Breatainn Mhòr Prydain Fawr Breten Veur Graet Breetain is the larger of the two main islands Spain () or the Kingdom of Spain (Reino de España is a country located mostly in southwestern Europe on the Iberian Peninsula. It has been suggested that genera within each of these particular areas do not form monophyletic groups. A clade is a taxonomic group comprising a single Common ancestor and all the descendants of that ancestor True boas are medium to large sized snakes. Females are usually larger than their males. Boas contain many subspecies based on locality. The boas from the Amazon Basin are the most colorful possessing bright cherry red tails. It used to be said that boas were New World Snakes and pythons were Old World Snakes, but, with boas found on Madagascar, Fiji, and Solomon Islands, this is not quite true. Fiji (Matanitu ko Viti फ़िजी officially the Republic of the Fiji Islands (Matanitu Tu-Vaka-i-koya ko Viti फ़िजी द्वीप समूह गणराज्य The Solomon Islands is a country in Melanesia, east of Papua New Guinea, consisting of nearly one thousand islands Instead, it is possible that boas have survived in evolutionarily isolated areas. South America, until a few million years ago, had a distinct fauna that included marsupial mammals; with the land bridge to North America, boas have migrated north as placental mammals and colubrids have migrated south. Fauna is all of the Animal life of any particular region or time Marsupials are an Infraclass of Mammals characterized by a distinctive pouch (called the marsupium) in which females carry their young through Mammals ( class Mammalia) are a class of Vertebrate Animals characterized by the presence of Sweat glands, including sweat glands See also Evolution of mammals Eutheria ("true beast" are a group of Mammals consisting of Placental mammals plus all extinct Mammals A colubrid (from Latin coluber, snake is a Snake that is a member of the Colubridae family.

Erycinae subfamiliy
Compared to true boas, erycines are quite small, with most members remaining well under a meter in length.

Common names bevel-nosed boas keel-scaled boas Candoia is a Genus of non-venomous boas found in mostly in Common names bevel-nosed boas keel-scaled boas Candoia is a Genus of non-venomous boas found in mostly in Fossil erycines have been found in rock strata over 50 million years old, and were once widespread in North America. Now, only two species remain in North America, as well as the sand boas in Africa, Asia and southeastern Europe.
At least three erycine species lay eggs: the Calabar Boa, (Calabaria reinhardtii) (once classified as a python for this reason); the Arabian Sand Boa, (Eryx jayakari); and the West African Sand Boa, (Eryx muelleri). In most Birds and Reptiles an egg ( Latin ovum) is the Zygote, resulting from Fertilization of the Ovum. Common names Calabar python burrowing python Calabar boa more.
