Recently I had some shrimp scampi from a restaurant and the shrimp were unnaturally white, a very bright white, and the skin of the shrimp was a bright red, not the usual dull orange. The meat of the shrimp was quite tough, more like a lobster than a shrimp.
Is this some special species of shrimp, or was the shrimp treated by some chemical process to make it that way?
