Horse-eye jacks

This morning, we encountered a sizable school of young horse-eye jacks (also known as bigeye jacks).  Although this species reaches 2 feet in length, this group of fish were only about 12 inches long.  Jacks are open-water predators that feed on smaller fish.  When they aren't feeding, they often hang out together and swim in a big, slow spiral.  Occasionally, we are able to get inside the spiral.  Today, we viewed it from outside.  These photos were taken at a depth of about 25 feet.
