Is it?

I found a research abstract about black snails from the Internet: black snails have short spiral shells with only the top of the shell and two conchoidal layers, the body conchoidal layer cannot fully accommodate the soft body, and the calcium carbonate content of the spiral shells is about 60.3%, which makes it easy to soften. On the back of the body grows the outer coat membrane and shell membrane, the outer coat membrane in the spiral shell wrapped around the visceral capsule, the shell membrane covers the surface of the spiral shell, can be extended in different directions. There are excretory holes in the shell membrane at the mouth of the shell, which are connected to the respiratory holes in the coat membrane, and they have multiple functions of respiration, fecal excretion and urinary excretion. It is proved that the black snail is a new kind of mollusk - the most primitive snail, and also a transitional species of terrestrial mollusks whose shells degenerate into inner shells. It belongs to the family Zonitidae (amber snails), the genus Hawaiia (amber snails), and the species Yishui amber snail (Hawaiia?yishuiuscule?Li).

If you ask his species is for how to raise him and worry, then you can rest assured, the snail is very good to raise I have also raised, from the discovery of his place to take some wet soil in the box to raise snails, spray some water every day, food with endive, green vegetables, lettuce, chopped earthworms can be.
