Crab claws are a delicious and low-fat source of protein, but pinpointing the exact protein content in a single claw requires looking at a few variables. The species of the crab, the claw's size, and the amount of edible meat inside all play a role. Generally, a small-to-medium crab claw may yield around 1 to 2 ounces of meat, while a larger one could offer more. Since most nutritional information is based on standard 3 or 3.5-ounce servings of total meat, an accurate estimate is possible by understanding the average content per ounce.
Protein content by crab species
Different species of crab yield varying amounts of meat and possess slightly different nutritional profiles. Here's a closer look at what you can expect from some popular types.
Snow crab claws
Snow crab claws are a popular seafood choice and are known for their delicate, sweet meat. A standard 3-ounce (85g) serving of wild snow crab claws offers around 14 grams of protein. Because a single claw contains a portion of this, you can expect a large snow crab claw to contain a substantial amount of protein.
Blue crab claws
Found primarily on the Atlantic Coast, blue crabs are a staple in many seafood dishes. A 3-ounce (85g) serving of blue crab meat is reported to have approximately 15 to 17 grams of protein, meaning a single, large blue crab claw with the arm will offer a significant portion of that amount. Smaller claws, however, will naturally contain less meat and less protein.
Stone crab claws
Stone crab claws are a regional delicacy, and the crabs are known for their ability to regenerate their claws. A 3.5-ounce (100g) edible portion of cooked stone crab claws offers about 16.2 grams of protein. Since these claws are larger and denser, a single, cooked stone crab claw can contribute a good amount of protein to a meal.
Dungeness crab
While Dungeness crab is often sold whole or as legs, the claws also contain meaty portions. A 3.5-ounce (100g) portion of Dungeness crab meat contains 17.4 grams of protein, and the meat from a large claw would reflect a portion of this high-protein density.
Estimating protein per claw
Since nutritional values are typically provided per 3 or 3.5-ounce serving, you can estimate the protein in one claw by considering the yield of meat. An average, large crab claw might contain 1 to 2 ounces of meat. With approximately 5 to 6 grams of protein per ounce for many crab types, you can estimate roughly 5 to 12 grams of protein per large, individual claw.
Comparison of protein in crab claws
This table provides a generalized comparison of the protein content in a 3.5-ounce (100g) edible portion for different crab species, offering a benchmark to understand the protein density.
| Crab Species | Protein (per 100g serving) | Calories (per 100g serving) | Notes on Claws |
|---|---|---|---|
| Snow Crab | ~20 grams | ~109 kcal | Claws are meaty and yield good protein |
| Blue Crab | ~18 grams | ~87 kcal | Whole claw with arm provides a good portion |
| Stone Crab | ~16 grams | ~95 kcal | Claws are often dense and offer a solid protein serving |
| Dungeness Crab | ~17.4 grams | Low fat and calories | High-yield meat, a large claw is a significant source |
The nutritional benefits of crab meat
Beyond its high-quality protein, crab meat offers several other health benefits. It is rich in vitamins and minerals and is low in fat, making it an excellent addition to a balanced diet.
- Vitamins: Crab meat is a great source of Vitamin B12, which is essential for nerve function and the production of red blood cells.
- Minerals: It contains crucial minerals like zinc, copper, selenium, and iron. Selenium is a powerful antioxidant, while zinc is important for immune function.
- Omega-3 Fatty Acids: Many crab species contain beneficial omega-3 fatty acids, which are known to improve heart health and brain function.
- Low-fat: Crab meat is naturally low in fat, with minimal saturated fat, contributing to a heart-healthy diet.

Conclusion
While it's impossible to state one definitive number for how much protein is in one crab claw without knowing the species and size, a reliable estimation can be made. Most large claws from popular species like snow crab, blue crab, or stone crab can be expected to contain anywhere from 5 to 12 grams of high-quality, lean protein. Considering its rich profile of vitamins and minerals, a crab claw is a healthy and flavorful addition to any meal.
