Description: He Fish-Skull' CrawBody is a realistic, anatomically correct crayfish ('crawdad') exoskeleton made of the same light-weight, synthetic suede material as the Fish-Skull Frantic Tails. They are easy to use enabling even a novice fly tier to create simple, but effective crayfish imitations. We offer the two basic crayfish colors_olive & brown_and. One of the great advantages of synthetic suede fabric is that it accepts permanent marker pen very well which allows fly tiers to make subtle color changes or markings as desired. Each suede body is precision laser cut making each body 100% identical and with very fine detail. Once in the water, the suede fabric absorbs water, gets a little darker and takes on a very natural looking 'leathery' appearance. The suede becomes softer, resulting in much more action from the free-moving crayfish claws.
