Brittle snail and stone snail are two common mollusks, and there are some obvious differences between them, which can be distinguished from their appearance, shell characteristics, living habits and so on.

First of all, from the appearance, brittle snails and stone snails are different in size and shape. The shell of brittle snails is usually small, conical or cylindrical, mostly taupe or brown in color, and the shell is smooth. The shell of the stone snail is relatively large, conical or cylindrical, generally brown or reddish brown, and there are obvious threads and tooth shapes on the shell.

Secondly, the characteristics of the shell are also the key to distinguish brittle snails from stone snails. The shell of brittle snail is brittle and easily broken, so it is named brittle snail. The shell of the stone snail is hard and has high strength, so it is not easy to break. This is one of the important differences between two kinds of snails.

Finally, there are differences in living habits between brittle snails and stone snails. Crispy snails mainly inhabit shallow seas, estuarine wetlands and other waters, and like to hide in shells, reefs or seaweed. Stonesnails are common in the sand and gravel on the coast and beach, and they can also cover themselves by drilling sand.

Therefore, according to the shape, shell characteristics and living habits, brittle snails and stone snails can be distinguished. If you meet these two kinds of snails in your life, you can refer to the above characteristics to judge.
