Within the animal species, there are several genera. Some are domestic and some are wild. Most people tend to believe that the wild ones are the most dangerous. Taking into account the concept of dangerousness according to which an animal is dangerous, when it has a certain capacity to make a lot of victims, it is found also among the domestic animals, the dangerous animals like mosquito, snake and snail.
The mosquito is a very small and insignificant invertebrate. But it is the cause of death for more than 750 thousand people a year around the world. The mosquito is the animal that man should fear most, especially the females who transmit sporocysts to man during their blood meal.
These sporocysts, once in the bloodstream, attack the red blood cells, causing them to lyse. This leads to diseases such as malaria and yellow fever.
These diseases, especially malaria, are prevalent throughout the world. Even researchers have not been able to find a vaccine to prevent them. There are also tiger mosquitoes, which are even more dangerous and multiply rapidly. This type of mosquito is even capable of biting in the middle of the day.
It is then found that the mosquito, despite its small size, is capable of inducing a very dangerous disease with a very high mortality rate.
The snake is a highly venomous animal and its bite is fatal to humans. After the bite of a snake, certain signs reveal the critical state in which the man is. Among these signs, the best known are nausea, an anarchic acceleration of the heartbeat, asthenia and even vomiting.
The snakes, although they are used to fleeing from man, feel obliged to face man and bite him when they feel attacked. With all this, one hundred thousand deaths per year due to snake bites can be recorded. This constitutes a large and not inconsiderable number of the population.
In the case of a snake bite, the best thing to do is to seek medical attention as soon as possible.
Snails are harmless animals, i.e. they do not attack humans. They are quiet and often live in close proximity to humans. Despite this, they carry parasites that can easily harm human health. For people living near water sources or in lakeside villages, they are at much greater risk of contracting diseases such as bilharzia, which is a disease known in various forms, each with its own genus of schistosome.
