There is a tiny creature with an amazing ability to put its eggs into a deep sleep. The ten-year hatching cycle of water flea eggs, also known as Daphnia, is quite remarkable. These little critters, which look like specks in the water, can be found in pools, ponds, and lakes all over the world. They might be small, but they have a big impact on their watery homes. And they have a pretty incredible survival tactic.
