%X The operational function of the trunk limbs (thoracic appendages), of <em>Daphnia</em>, P3 and P4, is a long-term disputed definition between ¡°solid walls¡±, sieving filters. Sieving is unlikely process for routine particle collection, particle capture is not a simple mechanical process and not by sieving alone. Analysis promotion supported by direct observational examination of the <em>in-vivo</em> cinematographic slow-motion film and magnified solid photos of tethered <em>Daphnia</em> by high-speed camera (250 frames per second) resulted in a definite interpretation presented in this paper. The <em>Daphnia</em>¡¯s feeding mechanism achieves particles abstraction not by sieving. The existence of two internal alternate water flow routs was indicated: Lateral and Median. These micro flow structures are suggested as vulnerability reduction.
