Liocranchia valdiviaeRichard E. Young and Katharina M. Mangold (1922-2003)
L. valdiviae is the deeper-water member of the genus. Younger stages are commonly taken but adults are rarely captured.
The paralarvae are similar to those of L. reinhardti. Prior to the development of the dorsal row of tubercles in the latter species, L. valdiviae can be recognized by its distinctive chromatophore pattern which includes three small chromatophores on the dorsal, posterior tip of the mantle and a larger patch of chromatophores on the posterior half of the dorsal mantle.
In Hawaiian waters L. valdiviae is not a diel vertical migrator although occasionally "wanderers" are found in shallow depths at night. The squid undergoes an ontogenetic descent and generally remains at its daytime depth at night.
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 capture.
