The Boa Constrictor Constrictor, commonly called Red-Tailed Boa, is one of the sub-species that make up the Boa Constrictor species, a large Ophidia found is wooded areas of the centre and north of South America. It is the only boa constrictor to have a reddish colour at the tip of its tail.
Sexual dimorphism is pronounced, as the females are significantly larger than the males. Their length can exceed 400 cm, and they can weigh more than 15 kg, although it is more common to find specimens between 300 and 350 cm. The males rarely exceed 240cm and can weigh over 7kg.
It is a boa of heavy, solid and muscular body with a strong and robust appearance. Its tail, somewhat prehensile, is short, a little less so in the male as this is where the reproductive organs are stored. The eyes are small, with vertical pupils, due to its nocturnal habits. Its head is triangular, with powerful jaws armed with 4 rows of large curved teeth at the top and two rows at the bottom.
This snake is largely terrestrial, although it tends to climb trees to seek refuge. It doesn’t inhabit water or its surroundings, although it is a good swimmer. It tends to regulate its temperature by sunbathing. It is unusual for it to live more than 20 years in the wild, but in captivity its life expectancy is between 30 to 40 years.
