Platypuses produce a variety of low growls, grunts, and high-pitched trills for social communication. Mothers use calls to signal presence to young in burrows. Males may use sounds during territorial disputes or courtship. Vocalizations are subtle, allowing covert communication in murky waters. Juveniles respond to maternal calls early in life. This vocal repertoire is more complex than previously assumed. Communication aids social coordination despite generally solitary behavior.

It ensures survival and reproductive success in dense habitats.
