Do seahorses have male and female organs?

Yes, seahorses are unique in the animal kingdom because the males get pregnant and give birth to live young. They have specialized reproductive organs to facilitate this. Male seahorses have a brood pouch, which is a pouch on the ventral side of their abdomen where they carry the fertilized eggs. The female seahorse deposits her eggs into the brood pouch of the male during mating, and the male's body provides nourishment and protection for the developing embryos until they are ready to be released.
