I DIDN'T KNOW THAT!

TOOK PIC OF THIS DRAGONFLY AT PINCHOT STATE PARK

A damselfly nymph breathes with gills at the end of its abdomen. The dragonfly nymph's gills, oddly, are inside its rectum. That's right, it breathes with its butt.

The dragonfly nymph will pull water into its anus, where gas exchange occurs. When the dragonfly expels the water from its rear, it propels the nymph forward, providing the added benefit of locomotion.

I have no idea why I just posted this except I liked the picture of the dragonfly at the lake, and it needed explanation. BUTT then, maybe it didn't.
