Every 100 kcal of cuttlefish brings 20.6 g of protein. On that measure it ranks 26th of the 121 seafood in this database and 39th of all 796 foods on the site. Measured by weight instead, its 32.5 g per 100 g ranks 4th in its group.
About 82% of the calories in cuttlefish 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, cuttlefish has 23.2 g of protein for each gram of fat (32.5 g against 1.4 g per 100 g).
Set against smoked sturgeon, another seafood entry in the database, a serving carries about 1.1 g more protein (smoked sturgeon has 26.5 g per 3 oz).
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 55% of the 50 g FDA Daily Value for protein.

Is the protein in cuttlefish complete?
Yes. The protein in cuttlefish supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own.
What share of the protein Daily Value is one serving of cuttlefish?
About 55%. One 3 oz cooked serving has 27.6 g, and the FDA Daily Value for protein is 50 g.
