Oregon State University researchers have made the first scientific confirmation in Puget Sound of two distinct shark species, one of them critically endangered.
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 inThe authors collaborated with partners at NOAA's National Marine Fisheries Service and the Washington Department of Fish and Wildlife to confirm that the broadnose sevengill, an apex predator that can grow to nearly 10 feet, is now inhabiting heavily urbanized...
Prior to 2021, only one sevengill shark had ever been confirmed in the Salish Sea, at Point Roberts, Washington, near the Canadian border. In August 2021, however, anecdotal reports indicated several of them had been caught in South Puget Sound. The same holds for the soupfin shark, said Personius, the lead author on that paper. It is the largest species of hound shark, can be as big as 6 1/2 feet and got its name because of its use as the key ingredient in shark fin soup.
In field work concurrent with the sevengill project, the scientists caught one soupfin shark, a male that measured just over 5 feet. Graduate student Maddie English is a co-author of the soupfin shark paper, along with scientists from the NOAA Marine Fisheries Service and the Washington Department of Fish and Wildlife. Research associate Alexandra McInturf contributed to the sevengill study.
