It’s not unusual in the culinary world to find seafood terms being tossed around interchangeably, but none is more misleading than the association between clams and scallops. Although they are both beloved in cuisines around the world, these two types of mollusks belong to different biological families and exhibit a variety of distinctive characteristics. This comprehensive guide will delve into the differences between clams and scallops, explore their unique features, and clarify why not all clams are scallops, while inviting you to appreciate both for their deliciousness.
What Are Clams and Scallops?
Before diving deeper into the distinctions, it’s essential to understand what clams and scallops are.
Defining Clams
Clams are a group of bivalve mollusks that live in marine or freshwater environments. They belong to the class Bivalvia and can be found in sand, mud, or buried in sediment. Clams come in a variety of shapes, sizes, and flavors, varying from the common hard-shell clams to the soft-shell varieties.
- Common Varieties: Quahogs, Manilla clams, Littlenecks, Soft-shell clams.
- Habitat: Most clams can be found buried in the seabed where they feed on organic matter.
Defining Scallops
Scallops are also bivalve mollusks, but they belong to a different family known as Pectinidae. Unlike clams, scallops are known for their distinct fan-shaped shells and their ability to swim by flapping their shells, a unique feature among bivalves. Scallops can be found in both coastal and deep-sea environments.
- Common Varieties: Atlantic sea scallops, Bay scallops, Japanese scallops.
- Habitat: Typically found on the ocean floor, often in sandy or gravelly substrates.
Comparing Clams and Scallops
While clams and scallops share certain similarities due to their classification as bivalves, several notable differences set them apart.
Physical Characteristics
When it comes to physical appearance, clams and scallops differ significantly.

What are the main differences between clams and scallops?
Clams and scallops are distinct types of mollusks with different physical characteristics and habitat preferences. Clams typically have a more oval or round shape with two symmetrical shells that are often buried in sand or mud at the ocean floor. They are generally characterized by their siphons, which they use for feeding and breathing. Scallops, on the other hand, have a more fan-shaped shell and are known for their ability to swim by rapidly opening and closing their shells. They are usually found in more shallow waters and are often found grazing on the seafloor.
Another key difference is their culinary applications. Clams are often consumed whole, either cooked in dishes or used in chowders and soups, while scallops are celebrated for their tender texture and rich flavor when pan-seared or grilled. Their unique flavors and textures make them suitable for different types of recipes, contributing to their popularity in various cuisines.
Are clams and scallops in the same family?
No, clams and scallops belong to different families within the class Bivalvia. Clams are typically classified under the family Veneridae, which includes various species like the quahog and the razor clam. Scallops, on the other hand, belong to the family Pectenidae. This classification highlights the significant biological and evolutionary differences between the two, despite their similarities as bivalves.
Moreover, the differences in their habitat and behavior further underline their distinct classifications. Clams tend to be more sedentary, burrowing into the substrate and filtering water for nutrients. In contrast, scallops can move around by swimming, which gives them a different ecological role in their respective marine environments.
