Here are more facts about sharks:

- Found Everywhere: Sharks live in all oceans, from warm seas like the Caribbean to icy Arctic waters.
- Secret Superpower: Sharks have a sixth sense! They can feel tiny electrical signals from other living things' muscles. This helps them find hidden food, even in murky water, and helps them navigate!
- Forward Only: Even with their swimming skills, sharks can only swim forward. They can't swim backward.
- Powerful Noses: A shark's nose is strong. They can smell things in the water from three kilometres away. That's like smelling cookies baking while you're still far from home!

Why We Need to Protect Our Shark Friends:
Sharks help keep everything in balance and make sure the ocean stays healthy for all the other creatures. But sadly, some people are hunting too many sharks. Why are they hunting sharks?
- For their fins: Sadly, some people want shark fins to make soup.
- For their meat and skin: Some people eat shark meat or use their skin to make leather.
- For their oil and cartilage: Sometimes, people use parts of sharks to make oils or things they think are healthy.
Because of this hunting, many types of sharks are in danger. We need to be their friends and help protect them!
