This stunning HD footage from the acclaimed BBC - Life series of two Weedy Seadragons showing off their courtship ritual is truly a sight to behold.
The Weedy seadragon is a marine fish related to the seahorse. It is found in water 3 to 50 m deep around the southern coastline of Australia. They resemble drifting weed when moving over bare sand but they have got nothing on their cousins, the Leafy Seadragon.
