Fun facts

1. Real diamonds don't show up in X- ray.
2. The ocean is 12,080.7 feet (3,682.2 meters) deep on average. That's about eight Empire State Buildings, stacked one on top of the other. The deepest part of the ocean, however, is about 36,200 feet down (11,030 m). That's more like 25 Empire State Buildings.
3. The male platypus has a venomous spur on its hind foot capable of dispensing a poison that can kill a medium-sized dog.
4. Mantis shrimp can use their armored claws to strike at speeds of 74 feet per second (23 m/s), delivering blows with 200 pounds (91 kg) of force behind them. The crustaceans are only about 4 inches (10 cm) long.
5. Seahorses don't have stomachs, just intestines for the absorption of nutrients from food. Food passes through their digestive system rapidly, so they eat plankton and small crustaceans almost constantly.
6. Scallops have as many as 100 simple eyes. They're frequently blue.
