Last week, researchers from Oregon State University documented two shark species in Puget Sound for the first time. They found a broadnose sevengill shark and the critically endangered tope shark. The presence of these large predators in the sound may mean that the ecosystem is changing to fit the needs of the sharks, which could have other effects. Taylor Chapple, assistant professor and head of the Big Fish Lab at OSU, joins us to share more about his team’s findings.
