 1. Yellow Anaconda description

The anaconda is a snake known for its impressive size. It has a massive head stuck in the neck. Short and square nose, small eyes implanted on the top of the skull (adaptation to semi-aquatic life), powerful and muscular body. Yellow to greenish-yellow color, with large black spots becoming smaller on the sides. 

This species reaches 2 to 3 m. The largest specimens can sometimes reach 4 or 5 meters. Females are larger than males. Finally, its longevity is 15 to 20 years in captivity, probably less in the wild.

The yellow Anaconda is, as said before, semi-aquatic and semi-arboreal. It cannot move quickly on the ground. Moreover, it avoids large dryland areas where parasites (ticks) are more numerous and more troublesome. Camouflaging itself in the water also allows it to surprise its prey more easily. It remains less dependent on water than its big cousin, the green Anaconda. It climbs trees to capture the sun's rays better and keep warm or escape a land predator. It spends its nights on the ground.

Like all Boas and Pythons family snakes, it is not venomous and kills its prey by suffocating it. It is a constructor. Highly precise, it rarely misses its prey when it attacks.

2. Yellow Anaconda diet

This snake has sharp teeth with which it captures its prey around, which it wraps itself to bring it to the bottom of the water and drown it. It feeds on large rodents, fish, turtles, birds, sheep, and pets. He watches for animals that come to drink, and that's how he catches them.

An anaconda does not chew, it swallows its prey head first, and since its jaws are disarticulated, it can swallow a capybara (the largest rodent in the world), but it will take 6 hours to do so.

After such a meal, the Anaconda will remain lethargic for 4-5 days and even several weeks, depending on the prey's size. It can even last for two years.

3. Yellow Anaconda reproduction

Males are sexually mature at 2 years, females at 3 years. It is a viviparous animal, meaning that the young are born already formed. Mating is done underwater, and the female can have a good dozen partners. After a gestation period of 5 to 7 months, she will give birth to 10 or 15 young, measuring between 60 and 80 centimeters.

The little snakes have to manage from birth, but few will survive because there are many predators. The Anaconda does not stop developing once it is an adult. This is why some are huge, up to 100kg per meter in length.
