Animals communicate using a variety of signals including visual signals like gestures, facial expressions, and color changes; auditory signals like sounds; olfactory signals through smells; electro signals using vibrations; tactile signals through touch; and seismic signals. Visual signals can include gestures of body parts, facial expressions, gaze following, and bioluminescence. Auditory signals involve using sounds to communicate, while olfactory signals use smells and tastes.
