As they cling to each other (much like this baby is clinging to its bit of seaweed), the female seahorse uses her ovipositor (egg-laying tube) to place anywhere between 50 and 2,000 eggs (depending on the species) into the male’s waiting pouch. The male jiggles around a bit to get the eggs into position in his brood cavity. Now, he fertilizes the eggs, which then stick to the spongy lining of his pouch. Having done her bit, the female seahorse proceeds to swim away, and the hard work is left to the male.
