re: Shrimps with heavy black on their back stripes...(now updated with pics)

I'll take a pic tomorrow evening when I get home from work, really don't think they are iqf as I bought them directly off the boat and even saw them coming directly from the hole. I don't believe they are tiger shrimp, and most of the shrimp is white, but black stripes from the collar on down. They did seem a little stronger than normal when eating them, and the ice water in my cooler darker than usual.
