Shrimp is one of the most popular seafoods on the planet, showing up in everything from Cajun gumbo to Japanese sushi. It's also one of the leanest sources of protein you can eat.

Here's what's actually true about shrimp, from its nutrition profile to how it's farmed and caught.

Shrimp range enormously in size, from tiny "salad shrimp" to jumbo tiger shrimp that can stretch several inches long.
Shrimp is low in calories and high in protein: a 3-ounce cooked serving has roughly 84-99 calories and about 18-24 grams of protein, depending on preparation.
Shrimp contains omega-3 fatty acids, which support heart and brain health.
Shrimp is a good source of selenium, an essential trace mineral involved in thyroid function and antioxidant defense.
A 3-ounce serving of shrimp has about 161 mg of cholesterol, but research shows dietary cholesterol from shrimp has a much smaller effect on blood cholesterol than saturated fat does.
Shrimp is a staple of Cajun and Creole cooking and appears widely in Asian cuisines, from sushi to stir-fries.
Most shrimp sold in the U.S. is farmed, though wild-caught shrimp is also widely available; sustainability depends heavily on the specific farming or fishing method used, not just whether it's wild or farmed.
Shrimp can be bought shell-on or already peeled and deveined; cooking with the shell on is often said to add richer flavor to the meat.
Shrimp can be boiled, grilled, baked, sautéed, or steamed, and takes on marinades and spices easily.
Shrimp is a go-to ingredient for appetizers like shrimp cocktail, shrimp scampi, and spring rolls.
Shrimp is one of the lowest-mercury seafood choices: FDA testing found commercial shrimp averages about 0.009 parts per million (ppm) of mercury, far below the FDA's 1 ppm action level.
Shrimp shells are edible and are sometimes fried until crisp, but most people peel them off before eating because they're tough to chew.
Boiled shrimp typically cooks in 2-3 minutes, while grilled or sautéed shrimp takes about 4-5 minutes; properly cooked shrimp turns pink and opaque.
Raw shrimp can be frozen for several months in an airtight container; the USDA recommends thawing it in the refrigerator rather than at room temperature.
Shrimp are decapod crustaceans, related to crabs and lobsters, and most species swim rather than crawl along the seafloor.
