''Crangon'' species are found exclusively in the Northern Hemisphere, with most of the species occurring in the northern

Pacific Ocean The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the contin ...

. ''Crangon septemspinosa, C. septemspinosa'' is the only species in the genus to occur in the north-western Atlantic Ocean, while in the north-eastern Atlantic, ''Crangon crangon, C. crangon'' and ''Crangon allmanni, C. allmani'' occur. With the exception of the important commercial species ''C. crangon'', however, the distributions of ''Crangon'' species are poorly characterised. The greater number of species in the Pacific Ocean is thought to indicate that the genus originated in the Pacific.
