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). | |||
