Here's why:
* Male Pregnancy: Male seahorses have a brood pouch on their abdomen where the female deposits her eggs.
* Fertilization: The male fertilizes the eggs in the pouch.
* Gestation: The male carries the eggs for several weeks, providing them with oxygen and nutrients until they hatch.
* Birth: The male seahorse then gives birth to tiny, fully formed seahorses.
This unique reproductive strategy is a fascinating adaptation in the animal kingdom!
