About the programme: http://www.bbc.co.uk/life
These two could teach Strictly Come Dancing a thing or two. Named for their uncanny resemblance to the plant life around them, a male weedy seadragon seduces a female with some very fancy fin work. Two months later, however, its the male whos left carrying the eggs

Living off the coast of south Australia, weedy seadragons (Phyllopteryx taeniolatus) are the only known species along with sea horses and pipefish - where the male carries the eggs. Although the eggs start out in the female, she lays about 120 of them onto the tail of the male where they are then fertilized and develop until they hatch.

Feeding on plankton, larval fishes and small shrimp-like crustaceans, seadragons resemble swaying seaweed making them difficult to find in their natural habitats, even though they can grow to about 46 cm in length.
