Sharks on the Shores?

And I’m not talking Sharky’s gift shop — a Web site devoted to shark sightings has the following posting — the big question is, were they really sharks, or dolphins? (No photo evidence):

Ocean Shores, WA  —  On July 31, 2009 Rick Chastain, his 4 year old son Cooper and 15 year old niece Kiara Drake were in between Damon Road and beach access West Chance A La Mer NW, Ocean Shores at Grays Harbor, Washington. There was a light fog with over a mile of visibility. It was 2:30 PM and the air temperature was approximately 70 degrees Fahrenheit. Chastain reported the following ; “I was watching three to four whales, about 300 yards off the shore, when I caught a glimpse of a dorsal fin in the breakers. As I watched more than one appeared, usually 30 – 40 feet apart from each other. They were traveling across the water rather than up and down. Then as we were watching a seal appeared between us and the sharks. We watched as the sharks would roll in the waves as they were breaking. The sharks would roll and the seal would show up 50 feet or so in either direction. They were actively chasing it up and down the shore. One shark would roll and before it made it under another would surface from the other direction. Then we would see another approximately 30 – 40 feet away from where the first had surfaced. I was watching the Seagulls and it did not seem that they were able to pick up any scraps. At least while I was there. We watched for an hour and they were still actively surfacing when we left. Whether they caught the seal or not I have no idea. But the seal kept surfacing quite aways from where the sharks were each time. I believe there was only one seal. There were many, many people enjoying the warm weather. Many were surfing with long boards and body boards, as well as using boogie boards. Most of them had no idea what was only 100 feet away from them. The sharks appeared to be 12 – 15 feet in length with a dark colored back and dorsal fin and a white underbelly.”
