Both lobster and crayfish are delicious seafood, and both are crustaceans because of their hard-outer shell. Both also have four pairs of legs, antennae, pincers, and a long tail. The chief difference is in size as adult crayfish do not grow past six inches. On the other hand, lobsters are typically eight inches long. Crayfish overall tends to be smaller.
A recipe that calls for a sea creature two to three inches long, you know that you will be serving crayfish and not a lobster. Lobsters can be found in oceans, while it is common to catch crayfish in lakes and streams. They live at the bottom, underneath rocks and muddy waters.
