This must have been one hungry little fish:
While fishing in about 1,400 feet of water off the South Coast of Grand Cayman, Mr. Wrightâ€™s attention was drawn to an object that was floating on the surface nearby. He motored over to investigate and picked up a dead fish that simply amazed him:
In the belly of the fish was another fish, and this one was clearly much, much bigger. In fact when it was measured it was determined that the fish he picked up had eaten a â€˜snake mackerelâ€™ that was more than four times its own length.
