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 southern 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.
