Such sizes are rare, boas reaching 3m are considered large. Two animals from Suriname are currently the largest on record: One reached 411cm (13.5 ft), the other 427cm (a bit over 14 ft). The largest animals have been found in Northern south America. Now, only two species remain in North America, as well as the sand boas in Africa, Asia and southeastern Europe.Īt 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).The size adult animals reach varies among subspecies. Fossil erycines have been found in rock strata over 50 million years old and were once widespread in North America. Sanzinia (Madagascar Tree Boa sometimes equated with Boa)Ĭompared to true boas, erycines are quite small, with most members remaining well under a metre in length. It has been suggested that genera within each of these particular areas do not form monophyletic groups (groups consisting of an inferred common ancestor and all its descendants).īoa (one species: Boa constrictor, also called the Red-tailed Boa)Īcrantophis (Dumeril’s Boa and Madagascar Ground Boa sometimes equated with Boa)

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. The Boa Constrictors from the Amazon Basin are the most colorful, possessing bright cherry red tails. Boa Constrictors contain many subspecies based on locality.

Sand boas are also frequently listed under their own family, ‘Erycidae’. Pythons are sometimes classified as a subfamily of Boidae, but are frequently listed under their own family, ‘Pythonidae’.

Boa Constrictors have two subfamilies: ‘Boinae’ or true boas and ‘Erycinae’ or sand boas. Boa Constrictors can been seen throughout the forest and sometimes in off shore caves. There, it is known as ‘Wowla’ to the natives of Belize. The Boa Constrictor (Boa constrictor) resides in the Rainforests of Belize, Northern Mexico and Argentina in South America.
