Genetic testing has determined that a new fish species, cedar sculpin, are present in the Coeur d'Alene and St. Joe rivers in northern Idaho.

U.S. Forest Service biologist Michael Young tells The Spokesman-Review in a story on Thursday that for decades biologists thought the minnow-sized fish was the more common shorthead sculpin.

Young says scientists found small variations and sent samples to a lab in Missoula, Mont. He says identifying the fish was a combined effort between the Forest Service and the University of Montana.

Sculpin are typically found in North America's major river systems.

Young says cedar sculpin probably emerged as a distinct species thousands of years ago.

He says waterfalls on the Spokane River likely blocked fish passage and cut off intermingling with othersculpin.
