This chapter discusses the distribution pattern of all of the genera, subgenera, and species groups of the Heterorhabdidae, Mesorhabdus, Heterostylites, Hemirhabdus, Neorhabdus, Paraheterorhabdus and Heterorhabdus. It notes that the distribution pattern of the Heterorhabdidae is very similar to that of the bathypelagic genus Paraeuchaeta and thus supports the hypothesis proposed by Park (1994), that endemic species with a limited geographic range are found exclusively in highly productive waters, where they are usually abundant. It further notes that they are therefore believed to be eutrophic. It observes that species with a wide range of distribution are generally rare and are believed to be oligotrophic, although the total number of specimens found in the study for some of these rare species was actually higher than the eutrophic species, because they occurred in more samples.
