The pressure drag reduction effect of tandem swimming by Caranx sexfasciatus and Rhincodon typus.

2021.05.31

Summary

Swimming in front of a large fish (whale shark) by a small fish (bigeye trevally) reduces drag force by up to 50% compared to a small fish swimming alone. It is suggested that the bigeye trevally swims in front of the whale shark to reduce the migration cost.

小型の魚類(ギンガメアジ)が大型の魚類(ジンベエザメ)の前方を遊泳することにより,小型の魚類単体で遊泳するのに比べて抗力が最大約50%削減される.ギンガメアジは移動コストを削減するためにジンベエザメの前方を遊泳することを示唆した.
