Soupfin sharks were not known to occur in Puget Sound until one was hooked by a fisherman in 2022. Scientists say warming oceans from a changing climate may be bringing more of the species into local waters. Our series on the sharks of Puget Sound continues with a closer look at soupfins and why they are being considered for inclusion on the Endangered Species List.

Bluntnose sixgill sharks are among the largest sharks in the world, reaching lengths of almost 16 feet. Research shows that Puget Sound may be an important place for sixgills to give birth and raise their young. We continue with part three of our series on Puget Sound's sharks.

The Pacific spiny dogfish is the most abundant shark in Puget Sound, despite its former decline due to overfishing in the 20th century. Part four of our series on sharks looks at this well-known Puget Sound resident and what is being learned about its migratory habits.

While several shark species are observed more frequently off the coast of Washington than in Puget Sound, some are seen on rare occasions in the inland waterways. Detailed information on these sharks is limited, but the same thing might have been said for sixgills, sevengills and soupfin sharks until recent discoveries opened the door to new research. Part five of our series on Puget Sound's sharks outlines some of our region's lesser known shark species. The following information comes from various sources, including fishing and scuba diving reports, scientific studies and the book “Fishes of the Salish Sea” by Theodore Pietsch and James Orr.

Local shark experts say people are often surprised to find that sharks are not ruthless eating machines; rather these animals display complex social behaviors and even personalities. They say the more that people learn about sharks, the more they will want to protect them. Our series on Puget Sound's sharks continues with part six of seven.

In the final installment of our series on sharks in Puget Sound, we look at how fishing regulations have changed to protect potentially vulnerable shark species. Experts say more regulations may be needed as research evolves.
