These seadragons were filmed at Flinders Jetty, Australia, when Pang Quong noticed the extraordinary engagement between the pair.

The sea creatures were spotted making their way to the surface of the water before exchanging eggs. Diving underwater at the Mornington Peninsula, Pang managed to capture the breathtaking moment between the two weedy seadragons on camera – a moment that Pang believes has never been observed in the wild before.
