1. Fertility Champions

In a world where size doesn't seem to have much of an impact on fertility, oysters have taken a masterclass on being "fruitful and multiplying": an adult female oyster has the astounding ability to produce between 50 and 100 million eggs every season, while their male counterparts churn out an uncountable number of sperm, making them one of the most fertile species on the planet.

2. Natural Water Filters

Why did the oyster start a cleaning business? Because it's fantastic at filtering: In fact, a single adult oyster can filter more than 50 gallons of water per day, effectively removing excess nutrients that could harm aquatic environments. Just imagine—one million three-inch oysters can eliminate 198 pounds of nitrogen and 22 pounds of phosphorus, turning their farming into a smart nutrient management strategy. So when you're slurping down that oyster, remember it's not just your taste buds it's keeping spotless, but the environment too!
