Distribution
Vertical distribution
In waters off Hawaii, Young (1978) found the distribution pattern shown on the right. Small octopods (ca. 5-15 mm ML) were found near 150-200 m depth or mostly below 600 m. One gravid female was captured at 1400 m. Two nearly mature males were taken at 1200 and 1425 m. Four brooding females were taken between 800 and 900 m.
