A kind of fish found principally in the Pacific Ocean, though a distant cousin, the Atlantic Salmon, can be found in the Atlantic. Salmon are usually a foot or two long, have grey-blue scales, and spend most of their time in the ocean, returning instinctively to the streams they were born in to spawn once a year. How they do this is subject to some debate: some think they navigate by the stars, others think they taste or smell the water. Both these theories are confused by the salmon near the mouth of the Fraser river in British Columbia, many of whom will, year after year, try to go through Boundary Bay (which used to be a passage though to the river - THOUSANDS of years ago), turn around, and go around it. Programmed in? Who knows. Salmon have a distinctive pink flesh, and are popular smoked and in sushi.
