[00:00:00]Have you ever seen millions of herrings release sperm all at once? Sounds unbelievable, right? But this isn't some mysterious or magical phenomenon. It's one of the most real and massive spawning events in the natural world.

[00:00:11]Millions of herrings simultaneously release sperm, enough to turn entire stretches of coastline a cloudy milky white. The scene is absolutely incredible. The protein-rich sperm mixes with the seawater, creating a strong almost indescribable fishy smell. When breeding season arrives, countless herrings leave the deep ocean and surge towards shallow coastal waters. A single female herring can lay anywhere from 30,000 to 100,000 eggs at once. The eggs are extremely sticky, allowing them to cling tightly to seagrass and rocks, even under pounding waves. There, they wait for the males to release sperm and complete fertilization. But after releasing sperm in these massive spawning events, many male herrings become severely exhausted. Some never make it back to the deep ocean. Using the last of their strength, they trade their lives for the birth of the next generation. About 20 days later, countless eggs begin to hatch, and newborn herrings pour into the sea. The coastline that was once turned milky white slowly returns to its original deep blue color, quietly waiting for spring to come again, and for this breathtaking spawning spectacle to repeat itself once more.
