A device for simulating and/or attracting aquatic life forms is disclosed. The device includes an electromagnetic module for simultaneously generating alternating or pulsed electromagnetic fields and a pulsed light output from a light emitting diode. The electromagnetic module includes a dry battery that is activated when exposed electrodes of the dry battery are placed in contact with a common electrolyte, such as sea water. The electromagnetic module includes a control circuit with one or more application specific integrated circuits for converting an input voltage from the dry battery to an operating voltage sufficient to power the light emitting diode. In further embodiments of the invention, the device includes one or more removable jackets that resemble aquatic life-forms.
