The one unique characteristic of ballyhoo and houndfish that I found in examining the contents of the stomachs of billfish many years ago is that you will find the bait in different directions and folded over. With most other baitfish (goggle-eyes, small bonito, etc.), the baits tend to lay headfirst in the stomach. When eating smaller baits, a billfish can do a quick head shake and turn it, so it is directed headfirst toward the gullet. And while the baitfish wiggles its tail to escape, it actually swims itself into the stomach. Guy Harvey has filmed a lot of this, and you can actually see it on film now. With a squirmy ballyhoo or houndfish, billfish have to force it down their throat after it’s been squeezed to death. Even in a swordfish, you find a lot of the squid in one direction in their stomachs.
