Biology     Glossary (e.g. epibenthic)

Caught by brails and night lights and pumps and night lights. Individual behavior: pale coloration indicates relaxation while dark, high contrast chromatic elements indicate alertness; protracted inking occurs after an abrupt stop from a backward jetting squid; in swimming, drag is reduced from the tightening of fin curvature which reduces the fin span relative to the average fin chord; fins and arms were used to maneuver. Schooling and shoaling: schools at night were tighter than during the day (Ref. 94861). Mating and egg-laying occur at daylight (Refs. 94843, 94849), egg beds found at depths of 20-60 m (Ref. 94843). Minor peak of spawning in November (Ref. 94827).
