I wondered about being a dolphin. Still a lot bigger than a carp! Also that would be a very big dolphin. Any of our Aussie brothers want to weigh in, I hear they see a few more sharks than we do.
Hard to say whether the rear fin is vertical ala shark or horizontal ala dolphin. Comparing the size of the person in the foreground, which should be artificially enlarged relative to the creature in the background, it would be huge for a dolphin. If the pic shows the dorsal fin to be curved in the rear it would be a dolphin or perhaps a pilot whale. Hard to tell. I have seen Bull sharks in the Bahamas cruising the waves like that right next to shore. .They are a man eating shallow water shark that also is cruises into sounds and up rivers here in NC. Very dangerous. Same shark was thought to have killed a male Russian and took off the leg of his girlfriend on the NC outer banks right next to the beach a year or two ago. Same shark killed a man's son at Virginia Beach. The father and the uncle pulled it on shore.
I was just about to say that. Anyways that would definetely make me faint. By the size of it I think that it's a shark for sure.
Swimming is no problem. Most of the water in the great lakes is very high quality. There are some issues with sediment in a few places. Unfortunaltly this creates problems in the food chain and large fish accumulate toxins in their fat. The end result is a limit on how much of the fish you should eat, especially the salmon.
Hmmm, I'm a tad biased. I was a kid in Sudbury in the early seventies... Industrial Foam was a pretty common sight on the lakes back then.
The first one looks to be a little bigger. But if you go on his site and you read and look I think that you'll find that its a dolphin. http://www.surfshooter.com/DolphinInfo.html
