It has been discussed for years, which is the most deadly animals on our planet, but now there is a new method called Crespo Scale.

What is Crespo Scale?

The Crespo scale developed by the author David Duarte Crespo measures how much an animal species poses for a random individual in a particular country. The scale lists the animals according to two main factors: population size (PS) and mortality (MR). While PS shows the possibility of encountering a dangerous animal in a particular country, MRI is calculated by dividing the estimated maximum number of deaths caused by a specific species (8 billion) of the global population (8 billion).

Crespo states that the reason for using these two factors is that these data is applicable to almost any species and that it is clearly measurable or predictable contrary to the features such as aggression. In addition, pets and people are excluded from this work due to their widespread widespread people.

Dangerous degrees and categories

The numbers representing PS and MRI are distributed between five points called Danger Degrees (DOD). 1 DOD score represents “not very likely” and 5 DOD points represents “very possible”. These numbers are multiplied and the total DOD value is obtained. The maximum dod value is 25, which determines which category to place the animal. Animals are listed between 1-5 depending on DOD value; 5 “Very High Danger” and 1 “Low Danger”. 3-5 categories are considered important threats.

And here are the most dangerous animals

Animals with sufficient data are included in this scale. Interestingly, the most dangerous animals in the 3-5 categories are usually in low and medium-income countries. Apart from the Russell Ege (Daboia Russeli), most of the animals that pose the biggest threats are disease carriers or parasites.

According to the Crespo Scale, the biggest threats are often identified as mosquitoes, Russell engine, blood worms and wild dogs.
