In February 2025, marine scientists saw whale sharks near St. Helena, a small island in the South Atlantic Ocean. These whale sharks are the largest fish in the world. They can grow to 18 meters long. Many male and female sharks were at this place. This is unusual because other places only have feeding whale sharks. Scientists believe this place may help whale sharks reproduce. This finding is important. It may help people know why the sharks go to this island.

Some scientists saw sharks do mating actions. Male sharks followed female sharks and touched their fins. Large whale sharks also swam close together. But no videos were taken. Whale sharks are now endangered. People must work to protect them. Some sharks got camera tags, but the tags fell off when the sharks swam very deep—over 2,000 meters. Tools now cannot go that far. In the future, better technology may help. Animal experts want to find the breeding places. This can help the shark population grow and protect the species.
