What is the only fish species where males become pregnant?
Answer
Seahorse
In seahorses, the male is the one who becomes pregnant. The female deposits her eggs into the male's brood pouch, where he fertilizes and incubates them until they are fully developed. The male seahorse provides oxygen and nutrients to the developing eggs, making seahorses one of nature's most unique reproductive examples.
💡 Did you know?
Male seahorses become pregnant with 100-1,500 babies; they regulate the baby's oxygen and salt intake like a placenta during pregnancy.
