The mean female size is 3.978 mm (n = 9; SD = 0.5585), and the mean male size is 3.785 mm (n = 10; SD = 0.5493). The size ratio (male : female) is 0.95 (n = 6; SD = 0.0752).

Remarks

epi-mesopelagic.
After Grice (1963, p.175) it is probable that Tsuryta's & al (1957) record of C. pacifica (= C. columbiae) from the tropical eastern Indian Ocean is a misidentification, because C. columbiae is a north Pacific cold-water species.
