Life History
Figure. Dorsal and ventral views of a paralarva of G. pacifica from Hawaiian waters, 4.8 mm GL. Note characteristic elongate mantle chromatophores.
Distribution
Vertical distribution
A study of the vertical distribution in Hawaiian waters (chart below) found most captures of squid greater than 20 mm GL in size came from depths of 700 m or more. This species does not appear to undergo diel vertical migration.
Figure. Vertical distribution chart of G. pacifica, modified from Young, 1978. Captures were made with both open and opening/closing trawls. Bars - Fishing depth-range of opening/closing trawl. Circle - Modal fishing depth for either trawl. Blue-filled circles - Night captures. Yellow-filled circles - Day captures.
Geographical distribution
Type locality - off Cocos Island, eastern tropical Pacific. Distributed throughout the tropical Indo-Pacific (Nesis, 1982).
