Since studying ocean biology， Thys has focused her research on how sea animals live.One animal she particularly studies is the ocean sunfish.“It's so different from any other fish，” says Thys.“It looks like a mistake.Where does the tail go？” Thys adds.“The sunfish provides an entry point to understanding more about the behavior of creatures in the ocean， and about how environmental changes impact underwater ecosystems.” Thys's work also takes her above ground， where she's looking at ways to create new connections between human populations and natural environments to help address social and environmental challenges.For instance， she's working on nature's effects on mental well－being. Thys's passion for her work is evident in every lecture， video， and public appearance she makes.Using the media， Thys encourages people to learn about the ocean and love it.Due to many ocean research projects and activities from the media， Thys is up to her neck in work every day.She could hardly spare plenty of time for a good rest.Thys's devotion to her work as an ocean scientist and ecological warrior is infectious.She's a role model and an inspiring guide to ocean life.
