<unk>  is a genus of tapeworm which can cause Diphyllobothriasis in humans through consumption of raw or undercooked fish.  The principal species causing diphyllobothriosis is<unk>  latum, known as the broad or fish tapeworm,  or broad fish tapeworm.  D. latum is a pseudophyllid cestode that infects fish and mammals.  D. latum is native to Scandinavia, western Russia, and the Baltics, though it is now also present in North America, especially the Pacific Northwest.
Other members of the genus<unk>  include<unk>  dendriticum (the salmon tapeworm), which has a much larger range (the whole northern hemisphere), D. pacificum, D. cordatum, D. ursi, D. lanceolatum, D. dalliae, and D. yonagoensis, all of which infect humans only infrequently.  In Japan, the most common species in human infection is D. nihonkaiense, which was only identified as a separate species from D. latum in 1989.
