Boa (Constrictor constrictor) spectacularly painted snake length of 2-3 m (up to 5,5 m). The main light-brown, reddish or coffee background back is covered with broad dark brown interceptions with bright yellow spots inside, and the sides are diamond-shaped dark spots, bordered by a rim light and a yellow spot inside. However, drawing on the body of a boa is so varied that we can describe a number of his other options. Viacom usually is spot on. In the sun glitters scales boa strong metallic sheen, and flowing iridescent snake in the motion. Scope of ordinary boa is very wide – from Mexico across the tropical and equatorial America up to the central regions of Argentina. On this vast territory boa constitutes about 6 subspecies, so clearly visible and in appearance and biology, before some of them were considered separate species. Nominal subspecies (S. with.
Constrictor) inhabit the forests of Brazil to the east of Peru and Colombia Venezuela, Suriname, Guyana and Guiana; Imperial boa (with S Imperator) – Peru, Ecuador, Colombia, throughout Central America and Mexico, Argentine boa constrictor (with S Occidentalis) – in the dry steppes of northern Argentina. Lifestyles of the ordinary boa in different parts of its range is very different. Brazilian subspecies inhabits the dense forests, readily climbs trees, and occurs frequently on the banks of rivers and streams, but the water does not go, preferring to search for food – small mammals, lizards, birds – on land. This might be due to competition from inhabiting the same areas anaconda, which hunts in the reservoirs and the coastal strip. Imperial boa constrictor is found in forests and among the thickets shrubs in dry areas, and comes in the middle belt of mountains. Argentine boa is not affiliated with any woody vegetation or the water it inhabits dry open landscapes. Common boa constrictor escapes also cultivated land, often meeting near human habitation, where hunting of rodents and lizards.
In some areas, he even almost “domesticated” – locals keeping boas in houses and barns, and they regularly catch rats and mice. Diet boas are very diverse – lizards, rodents (Agouti, Paca, marsupial opossums), birds (ducks, pigeons) and many other small animals. On the island of Trinidad ordinary boa the object of the hunt were delivered there mongoose, and it had great expectations in this respect, as imposed by the mongooses damage was significantly higher than expected from them. During the breeding season, which occurs at different times for each subspecies, Common boa brings 15 to 64 live young in length by two feet each. For two years they grow to 2-3 m in length and become mature. In captivity common boa willingly eats mice, rats, pigeons and chickens. Young boas are well tamed, adult snakes are often vicious, hissing and biting a man by careless handling. Boas live in captivity for about ten years, but sometimes much longer – up to 23 years.
