What is the scientific name of a carnivorous creature called "dirt road" in Hai 'an dialect?
"Dirt road" should refer to mud snails, and Hai 'an belongs to the southeast of Jiangsu. The dialect area from southern Jiangsu to Shanghai belongs to Wu dialect area, and the "Wu Nong Ruan Yu" is characterized by its small opening and shallow pronunciation position-that is, it feels that most of the sounds come from the parts of the mouth close to the teeth. Therefore, the snail sounds "Luo, Lu".

Bullacta exarata (Philippi) (English name say'spaper-bubble, Latin name Bullacta exarata) belongs to mollusks, Gastropoda, Subbranchia, Cephalotaxus, Adirondaceae and Bullacta (only one species of Bullacta), which is a special product of seawater and brackish water on the west coast of the Pacific Ocean. It is distributed along the coast of China. The body is rectangular, the head plate is large and thick, and the mantle is underdeveloped. The lateral foot is developed, covering part of both sides of the shell. The shell is oval, the larval shell is thin and brittle, the adult is hard and white, the surface seems to be engraved with spiral rings, the inner surface is smooth, and there is a yellow-brown epidermis. No steeple and umbilical cord, no sadness.

Life habit: The mud snail moves slowly. It digs out the sediment with the headboard, mixes it with the mucus secreted by the body, and wraps it on the body surface, which looks like a protruding tower of sediment and plays a role in mimicry protection. Adapted to the changes of temperature and salinity in life, easy to grow. Bullacta exarata is hermaphrodite, but during fertilization and sexual maturity, male and female snails can often be seen mating on the beach, giving birth to a round and transparent egg group, which is covered with colloid membrane, and each group has a colloid handle fixed on the beach. The dense egg flocks fluctuate in the water with the tide, which is very spectacular. When the water temperature is 25-28℃, the fertilized egg can complete embryonic development in 4 days, and the development speed will slow down at low temperature. In the development process, it experienced a floating life, and then changed into the benthic life of young snails.

Usually peach blossoms have the best quality when they are in full bloom. At this time, the snail has just begun to grow, and there is no mud in the body, which is sterile and delicious. Although the "osmanthus snail" produced in Mid-Autumn Festival is not as good as the "peach snail" produced in March of the lunar calendar, it is also rich in fat and extremely delicious. Bullacta exarata is rich in protein, calcium, phosphorus, iron and vitamins. Bullacta exarata is rich in nutrition and has certain medical functions. According to Compendium of Materia Medica, Bullacta exarata has the functions of nourishing liver and kidney, moistening lung, improving eyesight, promoting fluid production and quenching thirst. People also use wine stains to prevent and treat pharyngitis and tuberculosis.
