Every 100 kcal of scallops brings 18.5 g of protein. On that measure it ranks 42nd of the 121 seafood in this database and 69th of all 796 foods on the site. Measured by weight instead, its 20.5 g per 100 g ranks 83rd in its group.
About 74% of the calories in scallops come from protein, which makes it extremely protein-dense - close to the practical ceiling for a whole food. Foods in this band are the ones that let you raise your protein intake without raising your calorie intake much at all.
Weight for weight, scallops has 24.4 g of protein for each gram of fat (20.5 g against 0.84 g per 100 g).
Set against pacific herring, another seafood entry in the database, a serving carries about 0.5 g less protein (pacific herring has 17.9 g per 3 oz cooked).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving quoted here is measured by weight at 85 g, and it covers about 35% of the 50 g FDA Daily Value for protein.
