Prompt: Why do male seahorses give birth?

Outline: Start with the surprising statement that the father gives birth, then show the egg-transfer process through footage or clean biological animation. Explain how the male pouch protects developing young before they emerge.

Context: The role reversal is instantly understandable and supports a compact transformation from surprise to biological explanation.

Editorial premise: In seahorses, reproduction shifts pregnancy-like care to the male through a specialized pouch.

Audience promise: Viewers will see how seahorse reproduction works without confusing male birth with ordinary mammalian pregnancy.
