The Yaquina Bay samples were found near the Toledo Airport. “The widespread distribution of H. diadroma indicates that it is a successful invader of the North American Pacific and it may have long escaped detection because of its morphological similarity to the native species, H. limnicola. The long pelagic life of H. diadroma larvae could have facilitated its successful transocean dispersal with ballast water of ships.” (from the Abstract) ER -
