|Thomas Wright Blakiston (1832-91)|
Blakiston was the first to observe that fauna of the northern island of Hokkaido differed from that of Honshu. Thus the Strait of Tsugara formed a zoogeographical barrier of a type similar to the Wallace Line (previous post). It is referred to as the Blakiston Line.
