Wild Key West Pink Shrimp are exceptionally tender and sweet. Pink shrimp (Penaeus Duorarum) are the largest species of warm-water crustaceans collectively known as Gulf shrimp, a group that also encompasses white shrimp (Penaeus Setiferus) and brown shrimp (Penaeus Aztecus). While many shrimp are treated with chemicals to add water weight or extend their shelf-life and appearance, these shrimp are the highest quality gulf shrimp and have never been chemically treated.
