The difference between sea cones and textured snails lies in their different external features. The texture of the textured snail body is a line, not spiral, while the texture of the sea screw is coiled on the snail body. The price of the textured snail is generally a few yuan, while the sea screw is about 20 yuan.

Textured snails are commonly known as sea snails, sea lion snails, wheat snails or white snails. In some places, they are also called cut snails, small yellow snails and cone snails. It belongs to the phylum Mollusca, the class Gastropoda, and the family Velvetidae. The appearance characteristics of textured snails are that the tail is pointed and slender, with a length of about 1 cm and a width of about 0.5 cm, about the size of a fingernail. The textured snail is a poisonous organism. It is more toxic every spring and summer. After eating, it can cause poisoning symptoms such as dizziness, vomiting, numbness of the lips and fingers. The minimum incubation period is 5 minutes and the maximum is 4 hours. The Ministry of Health has banned the sale and operation of textured snails.

External characteristics:

From the outside, the textured whorl is like a cone, about the size of a fingernail, spiraling 8 layers, and the base is contracted. The textured snail has a pointed tail, a slender body, about 1 cm in length and 0.5 cm in width. The shell surface often has 1-3 purple-brown or reddish-yellow spiral strips, and the flesh is light yellow.

Related toxicity:

The textured snail itself is not toxic, and its fatal toxicity is obtained from the growth environment. Whether the textured snail is toxic or not depends on the food it has eaten. Because of this, red tide is generally considered to be the culprit of snail poisoning.

Most shellfish eat poisonous algae. When the snails eat toxic algae on rocks, they accumulate toxins in the body, which is actually the process of gradually accumulating toxicity on microbial algae such as Alexandria tamarensis and Salodora algae that are attached to the rocks. , it is precisely toxic algae.

There is also a theory that red tide is an important condition for the emergence of large-scale toxic snails, but this is mainly based on the premise that toxic red tide occurs when a large number of plankton gathers. As a result, once this environment becomes a gathering place for poisonous organisms, large areas of poisonous textured snails may appear.
