Berryteuthis magister nipponensis
Tsunemi Kubodera
Introduction
B. magister nipponensis was described by Okutani and Kubodera (1987) based on a single male holotype (182 mm ML) collected by a fixed net along Sanriku northeastern Honshu and a paratype (120 mm ML) collected in Toyama Bay, in the Sea of Japan.
Diagnosis
A Berryteuthis with ...
- slender muscular mantle, MW=22% ML.
- relatively small fins, FL=55% ML, FW=76% ML.
- slender tentacular club with numerous small suckers whichi extending about 45% of tentaclar stalk from distally.
- size differences between suckers of the median portion of club and those of marginal portion of club are less distinct than B. magister (holotype).

Life History
No informations is available for early life stages of B. m. nipponensis. Judging from the gonad development of the holotype, this species might be fully matured when relatively small in size (smaller than 20cm ML for males).
Distribution
The distribution of B. m. nipponensis is confined to the waters off Sanriku and Toyama Bay, northern Japan.
