Though crabs are omnivorous, meaning they eat both plants and animals, most of their diet consists of vegetation. Crabs primarily feed on algae and other types of aquatic plants, as well as small invertebrates like mollusks, worms, and tiny crustaceans.

In saltwater habitats especially, crabs are known to hunt for larger prey such as small fishes or snails. While these protein sources make up a smaller portion of their diet overall, they provide important nutrients necessary for a healthy crab life.

Considering their wild diet preferences, crabs kept in captivity can pose something of a challenge when it comes to mealtime. Most owners typically provide them with the same type of food they would find in their natural habitats, such as seaweed and algae. Commercial crab diets are also available, but should be supplemented with fresh fruits and vegetables for added vitamins and minerals. In addition to these plant-based foods, owners can give their crabs seafood like shellfish or shrimp to provide them with more protein.
