What is the smallest animal that kills most people?

The smallest animal that kills the most people is the mosquito.

Here's why:

* Disease Transmission: Mosquitoes are vectors for many deadly diseases, including malaria, dengue fever, yellow fever, Zika virus, and West Nile virus.

* Global Impact: Mosquito-borne illnesses affect millions of people worldwide, resulting in a staggering number of deaths annually.

* Size: Mosquitoes are tiny insects, making them difficult to avoid and control.

While some other small animals can be dangerous, like venomous spiders or snakes, their impact on human mortality pales in comparison to mosquitoes.
