Just as a cork screw on a wine bottle converts winding motion into forward motion, these tiny creatures spin their helical tails to push themselves forward in a world where water feels as thick as cork.
Proprio come un cavatappi applicato a una bottiglia di vino converte il moto a spirale in moto in avanti, queste minuscole creature ruotano le loro code elicoidali per spingersi in avanti in un mondo in cui l'acqua è densa come sughero.
