Read on to learn more about clams vs oysters – their taste, size, shape, color, which one produces pearls, and other facts used for even easier identification of each.

The 7 Key Differences Between Clam and Oyster

Taxonomy: Both clams and oysters are members of the phylum Mollusca, order Bivalvia. However, that’s where their similarities end and their differences begin. Clams are members of the family Veneridae and oysters, Ostreidae.Types: Both clams and oysters generally have two types, aside from edible and non-edible species. Whereas clams are divided into hard shell and soft shell, oysters are divided into true and pearl species.Habitat: There is some overlap in the locations of clams and oysters. Both can live in saltwater or freshwater. However, oysters are more commonly found in saltwater. Another one of their differences is in how they live. Clams live buried in the ocean floor and oysters live attached to rocks or other oysters.Body: There is some overlap in the size of clams and oysters from the smallest to the largest species. Both have pale white to tan meat. Also, they can have different colors and even different shapes, such as razor clams. It’s the texture of the shells that make for the easiest identification between them. Clam shells are exfoliated by the sand they bury themselves in, so they are smooth. Oyster shells are rough and bumpy with wavy lines.Taste/texture: Similarities in taste between clams and oysters are greatest if they are both saltwater or freshwater species. Hence, it’s the texture where the biggest differences lie and make for easy identification. Clams are chewy, but oysters are tender and can be slurped down. Clams tend to have a saltier flavor than oysters, and the taste can be very strong. Oysters, on the other hand, are often described as having a sweeter, almost buttery flavor.Nutrients: Both clams and oysters are low in calories and fat and excellent sources of protein, vitamin B12, zinc, potassium, calcium, and phosphorus. But whereas clams are rich in vitamin C, manganese, selenium and iron, oysters are rich in zinc, potassium, and phosphorus. These differences also account for their taste.Cooking: Oysters and clams can be cooked in many different ways or eaten raw. It’s how they are eaten that most distinguishes them. Although people can eat both oysters and clams raw, it’s far more common to eat oysters raw. Also, while raw oysters can be eaten with or without cocktail sauce, the sauce is necessary for eating raw clams. It’s also far more common to have clams in meals with other ingredients, such as clam chowder, or even with other seafood, such as paella. Oysters are often eat by themselves and as a luxury dish or appetizer, such as oyster shots.
