Answers

1. Sharks first appeared in the ocean during the Silurian Period, around 420 million years ago. This is about 200 million years before the dinosaurs.
   
   
2. There are over 500 species of sharks. The smallest known shark species is the Dwarf Lantern Shark, which can be as small as 17 centimeters in length.
   
   
3. Some sharks can detect a drop of blood in the water from as far as 3 miles (5 kilometers) away.
   
   
4. Whale sharks can grow up to 18-20 meters (60-65 feet) in length. They are filter feeders, meaning they feed by swimming with their mouths open to filter plankton and small fish from the water.
   
   
5. The three primary modes are oviparity (egg-laying), viviparity (live birth with a placenta), and ovoviviparity (live birth with the egg hatching inside the mother’s body).
   
   
6. The Great White Shark is known for the longest recorded migration, traveling over 12,000 miles (19,312 kilometers).
   
   
7. Approximately 25% of shark species are at risk of extinction. The primary threats include overfishing, habitat loss, and the demand for shark fins.
   
   
8. The Epaulette Shark is known for its ability to walk on its fins. It is primarily found in shallow waters around Australia and New Guinea.
   
   
9. The Goblin Shark is a deep-sea shark known for its distinctively long and flat snout. It’s rarely seen by humans due to its deep-sea habitat.
   
   
10. The Shortfin Mako Shark is considered the fastest shark, capable of swimming up to 60 mph (97 km/h). Its streamlined body and powerful tail contribute to its speed.
    
    
11. A shark can lose and regrow as many as 30,000 teeth in its lifetime.
    
    
12. These areas are known as “nursery grounds.” They are essential for the survival of young sharks, providing abundant food sources and protection from predators.
    
    
13. The Ampullae of Lorenzini are the organs responsible for electroreception. This sense allows sharks to detect the electrical impulses of prey, aiding in hunting, especially in murky waters.
    
    
14. The Greenland Shark can live for over 400 years, making it one of the longest-living vertebrates. It has a very slow growth rate and an unusual diet that includes carrion and other fish.
    
    
15. The Bull Shark is known for its ability to live in both saltwater and freshwater. It is often found in rivers and lakes, including the Mississippi River and the Amazon River.
    
    
16. Shark attacks on humans are extremely rare, with only about 75-100 incidents reported globally each year. In contrast, humans kill millions of sharks annually. This disparity highlights sharks’ generally non-aggressive nature towards humans and the significant impact of human activities on shark populations.
    
    
17. Sharks have a larger brain relative to their body size compared to many vertebrates, indicating high intelligence and advanced sensory capabilities.
    
    
18. The Megalodon lived approximately 23 to 3.6 million years ago during the Miocene and Pliocene epochs. Estimates suggest it could grow up to 60 feet (18 meters) in length.
    
    
19. The Wobbegong shark uses its patterned skin to blend with the ocean floor. It lies in wait for prey, using camouflage to ambush.
    
    
20. Shark finning involves removing a shark’s fins and discarding the rest of the body at sea. This practice severely threatens shark populations. Conservation efforts include legislation banning finning and trade restrictions.
    
    
21. This ability is known as endothermy. The Great White Shark can regulate its body temperature, allowing it to hunt in various water temperatures.
    
    
22. Sharks exhibit both solitary and social behaviors. An example of complex social behavior is the formation of large groups or “shivers” of sharks in certain conditions or for specific activities.
    
    
23. Remoras attach themselves to sharks for transportation, protection, and to feed on scraps from the shark’s meals. This relationship benefits both species.
    
    
24. The Thresher Shark is known for its long, slender body and unique tail, which it uses as a whip to stun prey, a rare hunting method among sharks.
