Exploring the world of scientific discoveries - Researcher encounters venomous snakes 40,000 times in study
A type of snake known as the Jararaca lance adder is responsible for the majority of snakebites in a certain area, leading to around 20,000 instances of envenomation annually. According to "Nature," Alves-Nunes put himself at risk by stepping on these hazardous creatures. His actions may potentially save lives.
In a discussion with "Science," Alves-Nunes shared that research into snake behavior is often overlooked. He examined 116 of these animals, pushing down on each of them 30 times each, resulting in a total of 40,480 steps near or on the snakes.
The study took place in an area measuring two square meters with an aluminum floor and polystyrene walls. The snakes were allowed fifteen minutes to adjust to their new surroundings before being approached. Alves-Nunes randomly stepped next to the snake or applied pressure to its head, mid-body, or tail. Both day and night were included in the experiment.
The analysis revealed that smaller snakes were more likely to bite, and females were more aggressive, especially if they were young and caught during the day. Higher temperatures also caused the snakes to be more agitated.
The probability of a defensive bite increases if you touch the head rather than the middle of the animal's body or its tail.
Alves-Nunes' Boots
Despite the foam-covered boots giving Alves-Nunes a sense of security, he was bitten by a rattlesnake during an experiment. Unfortunately, he had an adverse reaction to the antivenom, as well as the snake toxins. "Unfortunately, I discovered that I am allergic to both the antivenom and snake toxins," he stated.
Improved Antivenom Distribution
The researchers hope that the results of this study will lead to a more effective distribution of antivenom. In some areas, accessing antivenom can be difficult and time-consuming due to its lack of availability.
Alves-Nunes stated, "By combining our data with data from other studies on the distribution of snakes, we can identify the places where the animals are more likely to be aggressive. Prioritizing these areas for the distribution of antivenom is particularly important for regions with warmer temperatures and a higher proportion of female snakes."
