Feb 19, 2024 · The two species of green anaconda look almost identical, and no obvious geographical barrier exists to separate them. But their level of genetic divergence—5.5%—is staggering.
Feb 29, 2024 · Until recently, the green anaconda was thought to be just one species, Eunectes murinus, but a newly released study headed by Rivas found out there are actually two. The research describes...

A member of the boa family, South America’s green anaconda is the heaviest snake in the world. Its cousin, the reticulated python, can reach slightly greater lengths, but the enormous girth of the anaconda makes it almost twice as heavy. Green anacondas can grow to more than 29 feet, weigh more than 550 pounds, and measure more than 12 inches in di...
Anacondas live in swamps, marshes, and slow-moving streams, mainly in the tropical rain forests of the Amazon and Orinoco basins. They are cumbersome on land, but stealthy and sleek in the water. Their eyes and nasal openings are on top of their heads, allowing them to lay in wait for prey while remaining nearly completely submerged.
They reach their monumental size on a diet of wild pigs, deer, birds, turtles, capybara, caimans, and even jaguars. Anacondas are nonvenomous constrictors, coiling their muscular bodies around captured prey and squeezing until the animal asphyxiates. Jaws attached by stretchy ligaments allow them to swallow their prey whole, no matter the size, and...
Female anacondas retain their eggs and give birth to two to three dozen live young. Baby snakes are about 2 feet long when they are born and are almost immediately able to swim and hunt. Their lifespan in the wild is about ten years.
Though they originated in South America, green anacondas have spread through some Caribbean Islands and have been spotted in Florida. According to the Florida Fish and Wildlife Conservation Commission, they are not yet established and encounters are unlikely—however, they are considered an invasive species because of their size, the variety of anim...

Feb 16, 2024 · Anacondas, genus Eunectes, are a group of aquatic snakes with a wide distribution in South America. The taxonomic status of several species has been uncertain and/or controversial. Using genetic data from four recognized anaconda species across nine countries, this study investigates the phylogenetic relationships within the genus Eunectes.
Mar 1, 2024 · Researchers studying the genetic makeup of various types of anacondas in the Amazon rainforest over a period spanning 20 years have discovered that there are two genetically distinct types of...
