Polychaetes are only seldom inhabitants of fresh water; more often they are euryhaline (tolerant to variable salinities to brackish or fresh water) and in some instances they can be experimentally cultured in salt-free water. Nine species are known from North America. With few exceptions they inhabit streams or lakes which have, or have had, recent connection with the sea. Most of the species are small (a few mm long) and thus escape detection. They are members of widely dispersed families and are presumed to have originated separately in their unusual (nonmarine) habitats. Some differ from their nearest relatives in having modified methods of reproduction or physiological peculiarities. Some fresh-water polychaetes are members of monotypic genera, but many others are representatives of marine genera. Other geographic areas, notably South America (Correa, 1948) and southern Asia (Feuerborn, 1932), are known to have a more diversified fresh-water polychaete fauna.
