Underwater propulsion that leaves little traceable wake structure while producing high levels of thrust is a highly desired goal. A potential biological model is the California sea lion, a highly maneuverable aquatic mammal that produces thrust primarily with its foreflippers without a characteristic flapping frequency. In an effort to mimic the sea lion flipper, a flipper from a sea lion carcass has been scanned using several non invasive methods with the goal of manufacturing a robotic flipper with identical geometry. The scanning methods are hereby compared for overall quality, accuracy, and level of detail captured.

The aim of this study was to clarify postural control in the pitch direction using a combination of the flexion angles of the root and fin tip of the pectoral fin in Mobula japanica using Three-D-Computational fluid dynamics analysis. We made Mobula models that allow flexion of the tip of the fin and the root of the fin independently. It was revealed that independent pectoral fin flexion promotes a change in the velocity distribution around the body and, as a result, the pitch moment is generated.

Daphnia magna show strong positive phototaxis to blue light. Here, we investigate the effectiveness of behavior control of D. magna by blue light irradiation for their use as bio-micromachines. D. magna immediately respond by swimming toward blue LED light sources. The behavior of individual D. magna was controlled by switching on the LED placed at 15° intervals around a shallow Petri-dish to give a target direction. The phototaxic controllability of Daphnia was much better than the galvanotactic controllability of Paramecium.
