BIOMIMETIC FISH DEVICE A biomimetic fish device includes a fish-shaped shell unit having a plurality of shell members arranged adjacent to each other in a front-rear direction, and a plurality of rotating mechanisms each disposed within two adjacent shell members. Each rotating 5 mechanism includes a motor module and a rotating member respectively mounted within front and rear shell members. The rotating member is pivotably connected with the motor module about an axis in an up-down direction. The motor modules are controlled and operated individually to rotate the corresponding rotating members so as to drive rotation of the shell members relative to each other. The fish-shaped shell unit can be bent with 10 a plurality of smaller bending sections so as to imitate fish caudal fin locomotion.
