About the Anaconda

The green anaconda (Eunectes murinus), common anaconda, common water boa, akayima, or sucuri, is a boa species found in South America. It is one of the longest and heaviest known extant snake species. Like all boas, it is a non-venomous constrictor. Green anacondas generally have a life expectancy of 10 years in the wild, although some specimens live longer when they are taken care of in captivity. Green anacondas live in tropical rainforests and tend to prefer shallow, slow-moving waters, such as streams, rivers and flooded grasslands. They spend most of their time in the water but are also found on land in thick vegetation.

In the famous 10th edition of Systema Naturae of 1758, Carl Linnaeus cited descriptions by Albertus Seba and by Laurens Theodorus Gronovius to erect the distinct species murina of his new genus Boa, which contained eight other species, including Boa constrictor. The generic name Boa came from an ancient Latin word for a type of large snake. The first specimens of Boa murina were of immature individuals from 75 to 90 cm (2.5 to 3.0 ft) in length. In 1830, Johann Georg Wagler erected the separate genus Eunectes for Linnaeus's Boa murina after more... Wikipedia →
