mmm interesting about the snook and the frog. I bet you're right about the crab. Crabs and the way fish react to them is a very interesting topic.
One time I was anchored up on a blue hole and surrounded by permit; like thousands.
It was totally glass flat calm and I got up on the T top with a bucket of live blue crabs, a fly rod every permit fly known to man at the time, and my box of flytying stuff. I pitched live crabs and watched how they sank, and how they moved in the water. I watched the permit eat them, over and over. Then I began to dismember the crabs hoping to determine what it was about the crab that inspired the fish to eat it. I figured if I gave them parts missing crabs, one part missing at a time there would be a point at which they would no longer eat it. I would then take another crab with the "trigger part" still attached and toss it out to make sure. I had many many crabs and learned a great deal. Including that a dead crab, with all the parts still intact did not get eaten very often or until they had achieved a depth of 25'+.
The key seemed to be the little swimmers, plus a diagonal path, often zig zagging on it descent.
Not one of the flies I had, which was every single pattern, color and size of "local" permit flies got eaten. Not one. They might track it now and then, but never eat it.
I cut a curly tail from a piece of dental dam, secured it in two places so it's leading edge was parallel to the curve of the hook, made a flat body of trimmed brown deer hair with a flat piece of lead around 1/4 oz in weight secured with bone white epoxy to the belly. when I got the tail trimmed to the right length, they bit it immediately and I caught a bunch of them. Actually I made two flies and the people who were with me broke them off after I gave them the fly rod so they could see what it felt like to pull on one. I've not tied any since!
The little flippitys on the frog ain't all that far off a real crab, nor is the profile.
thanks for the post it gives me some ideas!
