A Quick Brief On How Seahorses Eggs Are Fertilized
Seahorse eggs are fertilized through a unique process that occurs within the male seahorse’s brood pouch. Here’s a simplified explanation of how seahorse eggs are fertilized:
- Courtship: Male and female seahorses engage in an intricate courtship dance, displaying their interest and compatibility.
- Egg Transfer: During courtship, the female deposits her eggs into the male’s specialized brood pouch through a tube called an ovipositor.
- Sperm Delivery: Once the eggs are inside the male’s pouch, he releases sperm to fertilize them.
- Fertilization: The sperm penetrate the eggs, fertilizing them and initiating the development process.
- Embryo Development: Inside the brood pouch, the fertilized eggs develop into embryos, receiving nourishment and protection from the male.
- Gestation: The male carries the developing embryos in his brood pouch for a period ranging from a few weeks to several months, depending on the seahorse species.
- Parturition: When the embryos have fully developed, the male undergoes contractions, similar to giving birth, and expels the newborn seahorses, called fry, into the water.
Now, let’s explain each part of it, from the moment of the egg reproduction to the egg transfer and fertilization:
