Remarks

± brackish, estuary-neritic.
The locality records in the Chinese and Korean seas seem to be confirmed.
After Shanthi & Ramanibai (2011, p.135) the dominance of species in the near shore waters from Cooum and Adyar (SE India) can be considered as an indicator of pollution status.

For Itoh (1970 a, fig.2, from co-ordonates) the Itoh's index value from mandibular gnathobase = 840.
After Wellershaus (1969, p.275), samples from water between 10 and 31 p.1000.
A doubt subsists on the synonymy between A. pacifica female in Wellershaus (1969, p.276) and A. spinicauda female.
