Observations and analysis of gut and waste contents from regularly flooded areas in the Pantanal region of southwestern Brazil indicate that they are generalist feeders that employ both ambush predation and wide-foraging strategies. In some cases, the female anaconda will eat a male anaconda. Origin South AmericaHabitat Tropical Rainforests, Marshes, and SwampsAverage Size Up to 20 - 30 feetLifeSpan 10 - 12 yearsGeneral Information Yellow Anacondas, Eunectes notaeus, originate from South America, specifically the Amazon Basin, Orinoco Basin, and Trinidad. In myths about the animals in some parts of South America, anacondas can appear as shape shifters. The head, however, is a bit wider. Here are several facts about this magnificent animal. Many snakes often group together and form a breeding ball, which may stay together for a month . Because of their length and weight, it is cumbersome for them to move on the ground. There are four categories of the anaconda: the green anaconda, the yellow anaconda also known as the Paraguayan anaconda, the Bolivian or Beni anaconda and the dark-spotted anaconda. [3] The species appears to have been introduced in Florida, although it is unknown whether the small population (thought to derive from escaped pets) is reproductive.[9]. Female Yellow Anacondas release a pheromone which entices the males to breed. Yellow Anacondas prefer to attack prey from the water and their victims often drown rather than suffocating.
Habitat destruction is another cause for concern for anaconda populations. Although they are at the top of their food chains, swallowing a large animal such as the jaguar may result in injuries that cause death.
In the movies, the animal is depicted as strong, agile, meticulous and cunning. Like all boas and pythons, it is non-venomous and kills its prey by constriction. They may have brown or black egg-shaped spots on the back of their bodies. They'll climb too, just most people don't give them the opportunity to do so. Looking at the Spurs on their skin, males have larger spurs than their female counterparts do.
[11], The yellow anaconda has few predators. They are also considered sacred. Their sides may at times be more yellow than they are green. These balls may last for weeks. They also have small scales on their bodies. There is some trade for their skins, but anacondas do not suffer to the extent of other species.
Its nostrils and eyes are located at the top of the head. After mating, the female carries the embryos inside her body for seven months and will not eat during this time to avoid injuries. They adapt to their surrounding with ease.
Habitat. Further information on etymology of generic name: Last edited on 2 September 2020, at 21:07, Synopsis of the species of Holcosus and Ameiva, with diagnoses of new West Indian and South American Colubridae, "Hay registros de anaconda amarilla (Eunectes notaeus) en el norte del país", "Eunectes notaeus (Yellow Anaconda). The animal ends up dying because blood could not reach the brain.
Where there is humidity, heat and a dense foliage of the rainforest, anacondas will thrive because the temperature is conducive for them to hunt and grow.
The color pattern consists of a yellow, golden-tan or greenish-yellow ground color overlaid with a series of black or dark brown saddles, blotches, spots and streaks. Description. Generally, both in length and weight, females are larger than male anacondas significantly. Their jaw is large and has loose joints that move when there is a large animal to be swallowed. This design is as unique to each snake as the fingerprint is to the human beings. In captivity the species has a reputation for being unpredictable and somewhat dangerous to humans. Once the anaconda gets everything figured out, it will attack its prey restraining it with its powerful curved teeth. Although in this wrestle the strongest may win, the female can also choose who she wants because she is bigger and stronger than the males.

Its physical characteristics make it stand out from other snakes. When born, the babies are surrounded by a membrane that they have to break out of. It is estimated that green anacondas can weigh up to 250kgs.
Unlike other boas, it is stocky, muscular and exceptionally large. Yellow Anacondas are yellow-green in colour with pairs of overlapping oval black spots: in fact, the pattern of yellow and black scales on the underside of the lower tail is unique to each snake. Their necks are thick and narrow. You will therefore never find a pack of them together unless it is mating season. This website uses cookies to improve your experience.

Larger specimens can prey upon larger animals, such as brocket deer, capybaras or peccaries. Dark-spotted. The yellow anaconda (Eunectes notaeus), also known as the Paraguayan anaconda[1] is a boa species endemic to southern South America. No subspecies are currently recognized.
Weights are also not known for sure. They too grow to about 9 feet just like most of the anacondas. For instance, anacondas that live in grasslands, bury themselves in mud during the dry season. Females produce a pheromone which attracts males. Yellow Anacondas live in swamps and rivers, and because they spend most of their life in or around water they are sometimes known as “Water Boas”. Female anacondas are longer that male anacondas. A female will grow to a height of up to 15 feet while males grow only to 10 feet.
The Neo-Latin specific name notaeus derives from Ancient Greek: νωταίος, romanized: nōtaios, lit.
Its constriction is thought to work in one of two ways, it will squeeze the lungs too tightly for them to work and the other is that it will break all the bones in a prey’s body. Near their cloaca region, anaconda’s scales have spurs. This structure is perfect for its aquatic life. Female yellow anacondas have reportedly been measured up to 4.6 m (15 ft). [1], The range of the yellow anaconda encompasses the drainage of the Paraguay River and its tributaries, from the Pantanal region in Bolivia, Paraguay, and western Brazil to northeastern Argentina[6] and northern Uruguay. The estimate may be off since the animal is not measured. Because of their size and their strength, it has been consistently dangerous for people to stretch the animal out to measure its full length. Usually, anacondas will hunt for their prey in the darkness. These anacondas have a yellow-green coloring. However, some countries have quotas for the number of snakes that they can export to zoos, for research or for the pet trade each year. Their prey consists nearly exclusively of aquatic or semi-aquatic species, including a wide variety of mammals, birds, reptiles, amphibians, fish and eggs. For the longest time, they were thought to either belong to the green or yellow anaconda species depending on which characteristics were most common in the snake. Their camouflaging color conceals them as they lurk in murky waters. This maybe the reason you want to find out more facts about the anacondas. They swallow their prey whole and, as they can unhinge their jaws, are able to eat prey much larger than the size of their mouths would suggest.

One female anaconda can have up to 29 babies: The number may be large or smaller depending on the size of the anaconda. There are also stories of the giant anaconda, which is often featured in movies, where the animal grew to 100 feet. Because their nostrils are on their heads, they can breathe and see while fully submerged in water. This activity is known as a breeding ball and it is most commonly associated with Garter Snakes[12]. Scientists say that the constriction power is so strong that it restricts blood circulation. [3] The prey-to-predator weight ratio is often much higher than for other types of Boidae. "[2], Adults grow to an average of 3.3 to 4.4 m (10.8 to 14.4 ft) in total length. These anacondas have a brown skin with black or dark brown spots. The name Eunectes is derived from the Greek word Eυνήκτης, which means “good swimmer”. Large prey takes a long time to digest, so anacondas may not eat for weeks or months after a kill. The males compete for the female, with the strongest and largest male often being the victor.
