摘要
Eighteen species of arrowworms have been found in Chazhma Bay (Peter the Great Bay, Sea of Japan) including 4 species (Leptosagitta ocis sp. n., L. Exigua sp. n., L. icis sp. n., and Oligosagitta entis sp. n.) described here as new. Some specimens showed peculiar morphological abnormalities, which have never been registered in arrowworms from volcanic bays and geophysically active regions. This paper analyzes the ecological situation in Chazhma Bay and presents a list of arrowworms species found there with descriptions and drawings of the new species and a list of morphological deviations registered in all species of arrowworms.
