Researchers used an old theory on vibrating plane wings to study how fish swim so well. They were able to double the swimming efficiency of their robotic fish over a range of speeds.

Researchers identified simple behavioral rules that allow these tiny creatures to collaboratively build elaborate structures, with no one in charge.
Even the best engineered filters get clogged eventually. Fish mouths have evolved structures that create unique fluid dynamics patterns that solve that problem.
