4. Around the globe, there exists a handful of
snakes capable of causingserious harm or death
to humans. Although the majority of snakes in
theworld are relatively harmless and capable of
inflicting only minor flesh wounds.
A small number of species are quite dangerous
to humans due to their aggressive behavior and
potent venom.
This Research Workexplores the 10 deadliest
snakes currently known to exist, based on an
analysis of their overall toxicity and potential
for human fatalities in the absence of medical
attention or appropriate antivenom.
