![]() ![]() At a mean of 200 grams and 68 centimeters, they are on average 1% of the mass of the female that gave birth to them. Green anaconda neonates are larger than most snakes at birth. Range length 3 to 12 m 9.84 to 39.37 ft.Males have larger spurs (7.5 millimeters) than females, regardless of the female’s size. The sex of an anaconda is also reflected by the size of the spurs located in the cloacal region. Females typically have a much larger mass and length than males, with males reaching an average of 3 meters in length and females 6 meters. There are records of 10 to 12 meter anacondas weighing up to 250 kg, though the actual maximal size of an anaconda is the subject of much dispute. Green anacondas are the largest snakes in the world. They also have a prominent black post-ocular stripe that runs from the eye to the angle of the jaw. Anacondas have dorsal nostrils and small eyes that are positioned on the top of the head. Their skin is soft, loose, and can endure extended periods of water absorption. The scale plates at the anterior portion of their body are much larger than those at the posterior end. Like other Eunectes species, they have narrow ventral scales and small, smooth dorsal scales. They have round dorsal blotches that are brown with diffused black borders, and are dispersed over the mid to posterior length of their body. ![]() Green anaconda coloration is characteristically dark olive-green dorsally, gradually changing to yellow ventrally. ( Duellman, 2005 Dunn and Conant, 1936 Grzimek, 2003 O'Shea, 2007 Schmidt and Inger, 1957) Like all snakes, anacondas have a forked tongue thay helps them locate prey and mates and to navigate their environment, in conjunction with the tubular Jacobson’s organ in the roof of the snake’s mouth. Boas have an external horny claw, a hind limb remnant that is more evident in males than in females. These boas can be distinguished from other constricting snakes by the absence of the supraorbital bone in the roof of the skull. ![]() deschauenseei (dark-spotted anaconda), and E. Green anacondas are one of four closely related species of constrictors, the other species being Eunectes notaeus (yellow anaconda), E. Green anacondas are semi-aquatic snakes that inhabit shallow, slow-moving freshwater habitats, as well as tropical savannas, grasslands, and rainforests. Small populations of green anacondas have also been introduced into Florida. Additional countries where they may be found include Ecuador, Paraguay, Bolivia, the Bolivarian Republic of Argentina, the Guianas, Guyana, Peru, Suriname, and Trinidad. This species is particularly common in the Orinoco basin of eastern Columbia, Amazon River basin of Brazil, and the seasonally flooded Llanos grasslands of Venezuela. Green anacondas are found throughout the tropical lowlands of South America. ![]()
