Lobster and Crayfish are very commonly differentiated by people and people find them very similar when looked at by the naked eye. However, that is not the case.
The differences between Lobsters and Crayfish are not limited to their select cooking styles. It goes way beyond, they both are a completely different set of animals and belong to different genetic families.
Lobster vs Crayfish
The main difference between crayfish and lobster is that the crayfish live in freshwater which includes rivers, streams, lakes, and ponds. Whereas, the lobster lives in saltwater which includes oceans and the sea. Also, crayfish are generally small while lobsters are comparatively large.
For the most part, lobsters are bigger than crawfish and can grow up to more than 20 inches. When lobsters are gathered for food, they are in any event eight inches in length.
Lobsters favor little sea creatures and at times, they become scavengers. The flavor and the surface of the squat lobster are like that of shrimps. Except if something else, both the taste and the surface of crayfish and lobster is equivalent.
This is a reason that Europeans sometimes refer to Lobsters as Sea Crayfish.

Crayfish live in freshwater and mainly eat plants, worms, and insects. Appearance-wise they are green in color. They are invertebrates i.e they do not have a backbone. They defend against their attackers using their strong claws.
Many people confuse between Crayfish and Lobsters and find them similar. People fond of eating seafood often refer to Lobsters as sea crayfish. They do so because Lobsters live in seawater while Crayfish live in freshwater.
Main Differences Between Lobsters and Crayfish
- Lobster belongs to the Palinuridae family while Crayfish belongs to Canbaridae, Astacidae, and Parastacidae family.
- Lobsters are found in North America while Crayfish are generally found in Europe. This is a reason that Europeans sometimes refer to Lobsters as Sea Crayfish.
- Lobsters are large in size. Crayfish are comparatively smaller in size. This is the reason for people in North America to often refer to Crayfish as mini Lobsters.
- Lobsters mainly eat small fishes, snails, and prawns while Crayfish mainly eat plants, worms, and insects. This differentiation in eating habits is seen in their texture.
