Hum, yes and no. Some parasites of salmon are dangerous of course, but here is a different feeling.<p>First because salmons are fishes. A common dolphin&#x27;s heart could easily pass by a human heart, is not really much different in size or shape, so when you spot a long worm titillating inside, you can&#x27;t help to make the connection in your mind and is specially disgusting.<p>And second because all is much bigger and more numerous in cetaceans and sharks.
