The oil snail is a carnivorous mollusk that lives on the deep seabed. From March to April every year, when the weather warms up and the water temperature rises, the oil snail begins to forage for food. After a winter of growth, the oil snail is particularly fat, this is the best time to catch the oil snail. The oil snail is delicious, rich in vitamins and proteins, and has a remarkable effect on relieving urination, foot odor, and headaches.

The oil snail is a cold-water predator that preys on bivalves or other invertebrates in the sea. Most are gastropods are coiled to the right, but some are typically left-handed. A very large stepped spiracular tower grows all the way up to the raised body shell order. The oval orifice has a short, wide suction duct. The ornamentation, if any, is confined to spiral lines, annular bands, or keels, although sometimes there are rough transverse growth lines. Substances secreted by the brain nerves of the conch can cause food poisoning. The incubation period for food poisoning caused by conch is as short as 1 to 2 hours, and the symptoms are nausea, vomiting, and dizziness, so it is important to remove the head of the conch during cooking.
