Oregon State University researchers have made the first scientific confirmation in Puget Sound of two distinct shark species, one of them critically endangered.

The presence of the broadnose sevengill shark and endangered soupfin shark in the sound, the southern portion of the Salish Sea, may indicate changes in what biologists in OSU's Big Fish Lab describe as an economically, culturally and ecologically valuable inland waterway.

The Salish Sea separates northwest Washington from British Columbia's Vancouver Island. The 6,500-square-mile body of water stretches into Washington as Puget Sound, and the sharks were caught close to Olympia near the sound's southernmost point.

Taylor Chapple, an assistant professor in Oregon State's College of Agricultural Sciences, and graduate students Jessica Schulte and Ethan Personius report the broadnose sevengill and soupfin documentations in papers published in Frontiers in Marine Science.
