During recovery I was scrolling through quora I found this great passage: “The most efficient killers in the animal kingdom are not lions.
Nope, not sharks.
The most efficient killers are dragonflies.
Dragonflies catch their target midair an astounding 95% of the time.
By contrast, lions, known for their hunting prowess, do so 25% of the time on their luckiest days.
Dragonflies devour their catch without even thinking about needing to land. Still in flight, they tear and swallow. Then they immediately move after another fly.
The nervous system of a dragonfly is able to focus on one fly, even when that single fly is in the middle of a cloud of other flies. It can track its target, calculate how fast it’s moving and in what direction, and intercept it.
The fly doesn’t know what hit it until it’s being chomped.
Dragonflies don’t just fly. They dive. They fly backwards. They hover. They have four transparent wings attached to their thorax, each one with its own muscle that moves independently from the others.
Their eyes are comprised of 30,000 facets – like pixels – that take up most of their heads. This means that as they fly towards you and as they fly away from you they can still see you.
I think mothers everywhere develop dragonfly eyes.
According to scientists, dragonflies have simple brains (less than a million neurons) that behave like complex brains when it comes to their ability for selective attention. (I want fly A. No, I want fly B. But I haven’t lost track of fly A.)
Do you know who supports dragonfly research? Among other organizations, the United States military.
The dragonfly is the dream high precision drone.” @dushkaamateur at Sheraton Grand Sydney Hyde Park
