Sharks: Diversity, Threats, and Conservation Efforts

The video discusses various shark species, from apex predators like the hammerhead and great white to filter feeders like the whale shark. Sharks have existed for over 440 million years, predating dinosaurs. However, some species are now threatened due to illegal fishing, particularly for shark fin soup.
