CHAPTER 3
DISTRIBUTION AND SYNONYMY
The euphausiids are restricted to the marine environment and do
not occur in areas of salinity less than about 28%,. Many sea areas have
been inadequately sampled but the general geographical distributions
of most species are known. Einarsson (1945) describes the distribution
of the species in the North Atlantic and Ponomareva (1963) and
Brinton (1 962c) provide information about species in the North Pacific.
Brinton (1962a) and Johnson and Brinton (1963) discuss the distribution
of euphausiids throughout the whole of the Pacific Ocean while other
authors, such as Nemoto (1965) describing euphausiids in the Kuroshio
Region, confine themselves to relatively limited geographical areas.
The so-called " distributional literature ) ) of euphausiids is vast and,
for the most part, beyond the scope of this book because we have not
attempted to define in detail the geographical limits of any one species
but only to define the general areas of occurrence of each species and
consequently only quote references which enable us t o do this.
