For example, after mating, a female anaconda often eats her mate, the male anaconda. The female species of the giant snake does not want to keep the male alive after mating. After mating, she wraps her body around the male snake and wraps it around her.
The Latin name of this species of snake is Eunectes acaima, meaning northern green snake. This snake weighs about three times as much as a human. It is almost as thick as a car tire. It lives in the deep jungles of the Amazon. There are many legends in the world about this giant snake of the Amazon, known as the terror of the water jungle. This snake is known as the messenger of death of the Amazon.
A rare and terrifying behavior of the female snake of this species is that after mating, she often eats her male partner. After mating, she wraps her body around the male snake and kills it, eating its flesh.
A chemical called pheromone is released from the body of a female snake that wants to mate. That smell drives multiple male snakes crazy. Sometimes the number is as high as a dozen. This is called a breeding ball. The competitors start fighting among themselves to get the mate. The seven females mate with multiple partners at the same time. Once the mating is over, it is the turn of the male snake to sacrifice himself.
But it is good to say one thing. The female green anaconda eats her partner not to survive herself. To show her child the light of the world. After seven months, the female snake gives birth to 20 to 40 babies.
Studies have shown that the weight of the offspring of female snakes that eat their mates is 25 percent higher than that of those that do not, and the survival rate of the offspring is 90 percent.
There are two divisions of the green anaconda. Earlier, scientists considered the green anaconda to be a single species. Later, it was found that the green anaconda in the Ecuadorian Amazon region and the green anaconda in the southern Amazon basin have genetic differences. The division was made on that basis.
According to the Natural History Museum, the green anaconda is the largest snake in the world. One report states that the heaviest snake ever recorded weighed 227 kg, was 8.43 meters long and 1.11 meters wide.
In addition to anacondas, sexual cannibalism is also observed in female bell frogs. Usually, the female frog attracts the male frog for vaginal intercourse. But she can change her mind just before mating.
She thought she would mate with the male frog and so she hunted him down. Female frogs of the Bell species swallow the male's penis not only before mating, but in some cases even during mating. This is what the female frog does to the male after mating.
