This figure is the Northern Snakehead, Channa argus , model 24 and figure 9 from the second series. These large, strictly freshwater predators are naturally found in the Korean Peninsula, China and Russia. Given the northern range, it is not surprising that they are cold tolerant, and have since been introduced to several other places including the US, Japan and parts of Europe (so far Canada has kept them out, but they are heading to the Great Lakes, so we’ll see how that goes) edit–at least no established populations since this was written.
