Article (All Levels)

Many people think sharks are scary because of movies and stories. However, sharks are usually not dangerous to people.

There are more than 500 species of sharks, and many are vulnerable or endangered. Sharks help keep the ocean healthy.

Scientists have also discovered that sharks can remember information, recognize simple number patterns, and even form friendships with other sharks.

Developed Article (B1–C2)

Despite their frightening reputation, sharks demonstrate remarkable cognitive abilities and surprisingly complex social behaviour. Studies show that some species can recognize numerical patterns, remember shapes for long periods, and distinguish between different quantities.

Researchers have also observed that certain sharks form stable social groups and learn from one another, challenging the traditional belief that sharks are solitary animals. These findings are changing public perception of these marine predators.

Unfortunately, more than one hundred shark species are now classified as vulnerable or endangered because of overfishing, habitat destruction, and climate change. Scientists emphasize that protecting sharks is essential for maintaining healthy marine ecosystems.
