The Snake River fine-spotted cutthroat trout is a form of the cutthroat trout (''Oncorhynchus clarkii'') which is considered either as a separate subspecies ''Oncorhynchus clarkii behnkei'', or as a variety of the Yellowstone cutthroat trout (''Oncorhynchus clarkii bouvieri'').〔 (【引用サイトリンク】title=Oncorhynchus clarkii behnkei )〕 The fish takes its common name from its original habitat, the Snake River of southern Idaho and western Wyoming, and from its unusual pattern of hundreds of small spots that cover most of its body, differing from the larger-spotted Yellowstone cutthroat pattern. Genetically it cannot be distinguished from the Yellowstone cutthroat trout,〔〔 and before the construction of dams there were no physical barriers between the ranges of the two subspecies in the Snake river drainage.〔 The subspecies was scientifically named in 1995 in a popular book by the columnist M. R. Montgomery, to honor the fisheries research of Dr. Robert J. Behnke, who had presented its (unnamed) description in 1992.〔Behnke R (2002) (Trout and Salmon of North America ) p. 175. The Free Press, New York, NY. (Simon & Schuster, electronic version 2010)〕 ==Hybrids== While fine-spotted x rainbow trout crosses are observed in the South Fork of the Snake River in Idaho, they are infrequently encountered and appear to be hatchery hybrids. Conversely, Yellowstone x rainbow crosses are common; the "cutbows" of Yellowstone Park in the Lamar River drainage are natural hybrids.
