When it comes to seahorses, it is the male that gets pregnant and gives birth to baby seahorses. The female swims to the surface of the water with the interested male in tow. It transfers its orange eggs into the pouch of the male which then adds its sperm and seals the opening. The growing babies will remain in their dad’s pouch till they develop. Once they are born the babies are on their own.
After completing an elaborate courtship dance that may go on for hours or days, the female seahorse transfers her mature eggs into the male’s brood pouch, where they are fertilized. At the end of a gestation period usually lasting from two to four weeks, the pregnant male’s abdominal area begins to undulate rhythmically, and strong muscular contractions eject from a few dozen to as many as 1,000 fully formed baby seahorses into the surrounding water. After that, the offspring must fend for themselves. Large litters are necessary because only about 0.5 percent will survive to adulthood.
Many, if not all, of the 47 known seahorse species—14 of which were identified only in the 21st century—are in decline worldwide.
Because seahorses generally live in shallow, near-coastal waters, human activities including development, pollution, fisheries, and traditional medicine have reduced their numbers. At the same time, their universal appeal has worked against them; until recently, wild seahorses were often captured for the aquarium trade. The delicate creatures tend to fare poorly in aquaria, however. In recent years, captive-bred seahorses have shown promise as hardier tank-dwellers than their wild relatives.
