A biomimetic aquatic device includes a housing, a driving module, a cam, and a weight unit. The driving module is disposed in a receiving space of the housing, and includes a driving shaft rotatable about its own axis. The cam is mounted co-rotatably to the driving shaft, and has a cam groove formed in an outer surface of the cam and having at least a portion that extends spirally about the axis. The weight unit is mounted to the driving module, is movable along the axis relative to the driving module, and includes an engaging member engaging and movable along the cam groove. When the driving shaft and the cam are rotated, the weight unit moves relative to the driving module along the axis via engagement between the engaging member and the cam groove, thereby changing a center of gravity of the biomimetic aquatic device.
