A shellfish with hundreds of species divided into 2 classes: warm water or cold water. Cold-water shrimp generally are smaller and more succulent. Shrimp come in a variety of colors, including light brown, pink, red, grayish white, yellow and green. When cooked, most shrimp shells change color, such as from pink to bright red. Raw, unshelled shrimp can also be referred to as green shrimp.
Rinse raw shrimp under cold water and drain thoroughly. Tightly cover and refrigerate up to 2 days.
