Colonies of harmful snails have appeared in a new territory in the US

The 15-centimetre-long mollusk lays pink eggs on plants near water. When their eggs come into contact with the skin, they cause redness and itching of the skin, as well as tearing of the eyes. Egg laying is carried out weekly, thanks to which snails multiply rapidly.

Through them in the body of humans and animals can penetrate the lung nematode of rats, attacking the brain of the host and is a carrier of meningitis – a serious disease, often ending in death. The snails also have a devastating effect on ecological systems, destroying the flora that feeds a number of fauna living in the water.
