Written on
Chapter 1: Introduction to Deadly Cobras
Across the globe, various cobra species pose significant threats to human safety due to their potent venom. This guide delves into the ten deadliest cobras, ranking them based on their venom strength, aggression, and bite statistics.
Selection Criteria for Ranking
To determine the most lethal cobras, we established specific criteria. The potency of venom against humans and animals is the foremost factor. Additionally, we considered the frequency of bites, as some less-venomous species may have higher encounter rates with humans. Finally, we analyzed average fatality rates and the time taken for a victim to succumb to the venom without seeking medical help. This holistic approach provides insight into the overall danger posed by each species.
