What happened

Andrew Zinin Lead Editor The deadliest animals are not lions, spiders or snakes, but the tiny mosquitoes that suck our blood, make us itchy and infect us with disease.

Why it matters

Mosquitoes kill around 760,000 people every year, according to research site Our World in Data, with humans ourselves coming a distant second.

Common ground

This is because mosquitoes account for 17% of all infectious diseases, including malaria, dengue, yellow fever, chikungunya and Zika.

Perspective signals

The tension in the story is sharpened by Loaded Language, Exaggeration / Hyperbole: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
