#DYK ? #NoWay
1. **Octopuses Have Three Hearts**
Two pump blood to the gills, and one pumps it to the rest of the body. Interestingly, the heart pumping to the body stops when the octopus swims, making them prefer crawling to conserve energy.
2. **Sharks Can Live for Centuries**
Greenland sharks, for example, can live up to 500 years, making them one of the longest-living vertebrates on Earth.
3. **Bananas Are Berries, But Strawberries Aren’t**
Botanically, bananas meet the criteria of berries (developing from a single ovary), while strawberries don’t since they form from a flower with multiple ovaries.
4. **Butterflies Taste with Their Feet**
Their taste sensors are located on their feet, allowing them to "taste" leaves and determine whether they're suitable for laying eggs.
5. **Hot Water Freezes Faster Than Cold Water**
Known as the Mpemba Effect, under certain conditions, hot water can freeze more quickly than cold water, although the exact reasons for this phenomenon are still debated by scientists.
