Why are Dragonflies Interesting?

• Nearly all of the dragonfly’s head is eye, so they have incredible vision that encompasses almost every angle except right behind them.

• Dragonflies are expert fliers. They can fly straight up and down, hover like a helicopter and even mate mid-air. If they can’t fly, they’ll starve because they only eat prey they catch while flying.

• Dragonflies catch their insect prey by grabbing it with their feet. They’re so efficient in their hunting that, in one Harvard University study, the dragonflies caught 90 to 95 percent of the prey released into their enclosure.

What Do We Have in Common with Nature?

Echolocation is the ability to use sound, rather than sight, to detect the location of objects. Did you know dolphins and bats evolved echolocation in the same way?

That’s particularly interesting, because they are two animals that never come in contact. One’s domain is the sea–the other, the skies.

“Now, a study shows that this ability arose independently in each group of mammals from the same genetic mutations. The work suggests that evolution sometimes arrives at new traits through the same sequence of steps, even in very different animals.” – Elizabeth Pennisi

What do you think this means for people? If such diverse animals are connected on a fundamental level, what does this say about our interconnectedness as a human race? How much might we have in common with the natural world that we don’t yet realize?
