Seahorse

In a stunning role reversal, it is the male seahorse that ultimately gives birth to babies. Following an elaborate courtship ritual, the mom lays hundreds of eggs inside dad's belly pouch, which he then proceeds to fertilize. Following a month-long gestation period, the father releases numerous tiny seahorses into the ocean.
