The hydrothermal vent fauna has a high ratio of taxa specific for vent biotopes, i.e. obligate vent taxa (> 90% at the species level). This observation, together with the dramatic difference between the vent and regular non-vent deep-sea communities, has resulted in vent fauna being treated as a separate evolutionary and biogeographic unit (e.g. DOVE Workshop Report). In general, the large-scale biogeographical patterns of the hydrothermal vent fauna agree well with those of the non-vent fauna. There is a strong reason to believe that the distribution of both faunas on a global scale is controlled by the same factors. The effect of the "non-vent ocean environment" on the distribution of vent organisms occurs most likely through dispersal stages of vent organisms. Various examples show that the distribution of faunistic assemblages of different types (from different environments) is described by the same zonal regularities. Thus, similar latitudinal zonation is typical for fresh-water and terrestrial faunas; similar latitudinal and vertical zonation is found in faunas of continental slopes and seamounts. Global biogeographic patterns of abyssal and ultra-abyssal (hadal, or deep-sea trench) faunas are also in a good correspondence. On the community level, hydrothermal vent fauna indeed clearly differs from the non-vent one. However, there is not enough reason to distinguish separate hydrothermal and non-hydrothermal biogeographical provinces. The distribution of vent and non-vent faunas on the global scale is most likely controlled by universal factors and both faunas belong to the same biogeographical provinces.
