Shooting gobs of water at targets requires quick changes and fine control
Ingo Rischawy (Schuster lab, University of Bayreuth)
When archerfish hunt by precision spitting water into the air, they do a lot more with their mouths than put their lips together and blow.
If a Toxotes archerfish can’t jump high enough to snatch an insect off an overhanging leaf, the fish spits a water stream upward that knocks prey off its perch. In a quirk that puts extra punch into the water blast, the fish fires the trailing end of a water stream faster than the water released at the beginning.
