Аннотация:A new species of the rare and poorly studied genus Doridunculus G.O.Sars is described
from the deep-sea basin of the Sea of Japan (depth 3000-3620 m). Doridunculus unicus sp. nov. differs from the two other known representatives of the genus by a complete absence of the notal crests, asymmetrical notal lobes and by details of its radula structure. For
the new species the unusual feeding ecology was revealed. D. unicus sp. nov. lives within huge accumulations of the colonies of hydroids Egmundella sp. (Campanulinidae) and feeds on these hydrozoans (numerous broken fragments of Egmundella sp. were found in the oesophagus, stomach and intestine of the new species).
