Abstract
A new species of chaetognaths, Sagitta dimitryi sp. nov., was discovered in the waters of the Sea of Okhotsk, near the northwestern part of Sakhalin. The aim of this article is to describe the new species. A table of identification keys for species of the genus Sagitta is given, including Sagitta dimitryi sp. nov. The relationship of modern Sagitta with ancient Chaetognatha is discussed, including possible reasons for the evolution of the intestinal apparatus.
