The larva of the hermit crab Diogenes nitidimanus Terao, 1913 was found in the ballast waters of the tanker Minotaur that arrived from the Chinese port of Laizhou (Bohai Bay, Yellow Sea). Earlier, an abundant population of mature adults of D. nitidimanus was found in Vostok Bay (Peter the Great Bay), this suggested the introduction and naturalization of this species in the Peter the Great Bay.
