Weaving snails, commonly known as conch, sea lion snail, wheat snail or white snail, are also called cut sweet snail, small yellow snail and trypanosoma in some places. It belongs to mollusca, Gastropoda, Odontomyiidae. Snails are characterized by a sharp and slender tail, about 1 cm long and 0.5 cm wide, which is about the size of a fingernail. Weaving snail is a poisonous creature, which is more toxic every spring and summer. After eating, it can cause dizziness, vomiting, numbness of lips and fingers and other poisoning symptoms. The shortest incubation period is 5 minutes and the longest is 4 hours. The Ministry of Health of the People's Republic of China has banned the sale and management of snails.
External characteristics:
From the outside, this snail looks like a cone, about the size of a nail. It circled eight stories, and its foundation contracted. Snails have a sharp tail and a slender body, about 1 cm long and 0.5 cm wide. There are often 1-3 purple-brown or red-yellow spiral bands on the shell surface, and the body is light yellow.
Related toxicity:
Weaving snail itself is not toxic, and its fatal toxicity is obtained from its growth environment. Whether a snail is poisonous depends on the food it eats. Because of this, red tide is generally considered as the chief culprit of snail poisoning.
Shellfish mostly feed on toxic algae, so that toxins are enriched in the body and become toxic organisms. Snails eat toxic algae on rocks, which is actually a process of gradually accumulating toxicity. Microalgae attached to rocks, such as Alexandria tamarense and Dunaliella salina, are toxic algae.
There is also a saying that red tide is an important condition for large-scale poisonous snails to lay eggs, but this is mainly based on the premise of toxic red tide. Red tide is formed by the accumulation of a large number of plankton. Once this environment becomes a gathering place for poisonous creatures, a large area of poisonous snails may appear.
