Seahorses just love shrimp. Seahorse fry (baby seahorses) eat an amazing 3,000 pieces of food a day.
Seahorses live in shallow weedy areas, especially eel grass beds. They are found in most parts of the world outside of the Polar regions.
Seahorses are often used in traditional Asian medicine. They are also often caught to be sold as pets, or to be dried out and sold as souvenirs.
Seahorse males are the only males in the world that can get pregnant. The female transfers her eggs to the male. He then carries them until the baby seahorses (called fry) are born.
