Dragonfly Larvae / Chris Hoving / LicenseCC-by-nd - Attribution No Derivatives

The larvae of dragonflies squirt water out their anuses to lunge forward after prey thanks to hydraulic linkages.

BIOMIMICRY TAXONOMY
Summary
"Hydraulic linkages occur in a wide variety of biological systems…In addition, one can point to the predatory strike of dragonfly larvae, which lunge forward by squirting water out their anuses (Tanaka and Hisada 1980)…" (Vogel 2003:420-421)
