Orcas, also known as killer whales, are highly social marine mammals famous for their complex clicks, whistles and pulsed calls, which they use to communicate and hunt in pods. Their distinctive vocalisations have long featured in nature documentaries and wildlife footage, helping audiences recognise them instantly. Online, short orca clips are now shared on soundboards and in video edits as a quick shorthand for the ocean, intelligence and wild power, because even a second of the call carries a strong sense of place.
