Shellfish is a term used to describe a range of aquatic life used as seafood. They are animals that dwell in water and have a shell or shell-like exterior. Shellfish can be divided into two groups: crustaceans and mollusks. Crustaceans include shrimp, crayfish, crab, and lobster, while clams, scallops, oysters, and mussels are examples of mollusks. Cephalopods like octopus, squid, and cuttlefish are also technically shellfish despite their lack of external shells, as they fall within the mollusk family.
Shellfish are rich in lean protein, healthy fats, and minerals, and regularly eating them may boost immunity, aid weight loss, and promote brain and heart health. However, shellfish are one of the most common food allergens, and some types may contain contaminants and heavy metals.
Here are some of the most popular types of shellfish:
- Crustaceans: crab, crayfish, lobster, prawn, and shrimp
- Mollusks: clams, mussels, oysters, scallops, snails, octopus, squid, and gastropods
Shellfish can be prepared in different ways and are eaten all over the world for centuries. When buying shellfish, its best to buy from a vendor you know, and for the best ocean-fresh flavor, buy and eat shellfish the same day.
