Tagged large males were apparently unsuccessful in mating, as evidenced by the short time they spent near the egg beds. In contrast, paired males escort female mates to the egg beds and guard them as their eggs are deposited (Fig. 3). This does not necessarily imply that tags interfered with normal behavior, because males outnumber females. Most squid moved offshore at dusk; one large male was tracked 2 km offshore, where he remained relatively stationary (perhaps feeding or resting) until his return at dawn. During this male's onshore migration, his mean swimming speed was. as expected. 1 body length per sec- ond (45 cms"1), three times his speed in the mating arena. In contrast, sneakers were smaller and faster, av- eraging nearly 1 body length per second for the whole day; their tactic of avoiding large males and achieving sneak EPCs requires swift Figure^.
