Yes, White Sea roundworms

Roundworms (Nematoda) is a group of mostly parasitic worms found pretty much everywhere. Naturally, Russia and the former Soviet Union haven't been spared the tremors. “Nematodes and their role in the Meiobenthos” is a book by T A Platonova and V V Galtsova. The Russian-language version was published by Nauka in Leningrad back in 1976, while the translation is dated 1985. For some reason, it's printed in Faridabad, India. The book is marked Volume XV (XXIII) of “Studies on Marine Fauna”, or rather “Issledovanie Fauny Morei”. It includes two highly technical sections, “Lower Enoplida of the Seas of the Soviet Union” and “Free-living marine nematodes as a component of the meiobenthos of Chupa inlet of the White Sea”. The illustrations are black-and-white drawings of (scary) diagnostic characters of nematodes. We're talking parasitical worms here, remember?
