On a recent swim, I was turning to head for home when I saw this large school of fish rocketing towards me. As they zipped by I snapped the top photo. I could see they were mackerel scads, known in Hawaii as Opelu.
The reason for their haste also became clear as the last of them went by. The bottom photo shows a rainbow runner hot on their tails. Both fish are members of the jack family, but it’s a family that doesn’t get along. Mackerel scads are a favorite food of rainbow runners.
In a matter of moments, the fish disappeared out of sight. These were the only two photos I was able to take of the episode and I was thrilled that both turned out pretty well.

Seeing a big school of fish, like a flock of birds, is a great experience. How they can move in unison the way they do is beyond me.
