Unveiling a 7.5-Meter Giant Anaconda: A First Encounter in the Amazon with Will Smith

Four new species of eyelash vipers, it is on the side of the Anacondas that the family is now growing! Anaconda would actually be made up of two species, one of which is disappearing, according to a scientific article published in 2024.

Male or female, a drastically opposite physique

As part of a documentary series by National Geographic, entitled Pole to pole With Will Smith, Professor Bryan Fry at the University of Queensland, began to study the impact of oil drilling in the Amazon on long -term local flora and flora, in close collaboration with the Waorani, an Aboriginal people.

According to the researcher, the physical aspect of the anacondas varies considerably according to the sex of the snake. Indeed, the females measure about 5 meters, but the males are twice as large. Therefore, their diet is drastically different, to suit their respective energy needs. As the anacondas are higher predators, they are very vulnerable to the degradation of the habitat.

A species in Brazil, a species in Ecuador

Also, the idea for Bryan Fry and his team of scientists is to compare the concentration of heavy metals in the body of snakes, to detect the consequences of oil spills in the wild. In conclusion, males have 1000% in addition to lead and cadmium in their bodies than females. The males are fond of waders (birds living in aquatic environments). As for females, they prefer grazers. This proves how much oil infiltrates the aquatic ecosystem to go up the food chain to the big serpent.

It was during this study that scientists discovered that the Green Anacondas of Ecuador were larger than those in Brazil. As for the largest females, they are shorter by one meter on average. After taking genetic samples, the team of researchers came to the conclusion that these two different territory snakes do not actually belong to the same species, although their appearance and behavior is significantly identical.

Thus, it is the Brazilian species that is in danger, because of its relatively smaller distribution area than the species of Ecuador. In addition, “hydrocarbon pollution affects the male fertility” of the anacondas, according to Bryan Fry.
