The quantitative distribution of meiobenthos from 70 m to 1116 m is di
scussed. The nematodes are the main group in eumeiobenthos, the juveni
les of polychaetes predominate in pseudomeiobenthos. The decrease of t
axonomic diversity is due to the increasing depth. The quantitative di
stribution of meiobenthos correlates with the type of bottom sediment.
