"I think the genetic study is a tremendous first breakthrough into our understanding of the movements and population associations between whale sharks in different parts of the world," Norman said. "All types of research add to our understanding of this cryptic species." Still, Norman said, the work is in its early stages, and more needs to be done. His studies using photographs to identify and track hundreds of whale sharks based on their unique patterns of spots suggest that most whale sharks actually stay close to home most of the time. Many are spotted in the same places year after year. As scientists work to learn more about whale sharks, it's worth making efforts to protect them now, Norman said. In a new study in Endangered Species Research, he and colleagues reported that a population of whale sharks that lives in Ningaloo Marine Park in Western Australia is maintaining its numbers and even increasing slightly, thanks to careful monitoring and management. "Hopefully," he said, "We can take that message to other parts of the world."
