Bitter snails are distributed in all parts of China's coastal areas and generally live in rock crevices in the upper intertidal zone. They are one of the most common snails in the intertidal zone. Feeding on barnacles and bivalves.

Bitter snails like to stay in places with uneven rocks, and they are exposed to broad daylight after low tide, which has become a hobby of women and children in fishing villages besides picking up shells. However, there are only small spicy snails on the surface of the reef. Those big spicy snails obviously have the experience of avoiding risks and are still hiding in the cracks of underwater reefs. This requires the help of tools.
