More and more cases reported in Germany - expert expresses fears

In Germany, cases of a species unknown until recently are increasingly reported. These newly discovered land planariums, especially the art Caenoplana Variegata , show a worrying spread. These carnivorous whirlpool worms are unable to seriously damage people, but they are a threat to local ecosystems.

distribution and discoveries

The Zoological State Collection in Munich already pointed out the increasing spread of carnivorous whirlpool worms in January. In total, at least 25 non -domestic types of country planariums have established themselves in Europe in recent decades. The discovery of Caenoplana Variegata in North Rhine-Westphalia is particularly worrying, where several sightings from cities such as Cologne and Jülich have been reported.

causes of the spread

An expert in amphibians and reptiles, Dr. Frank Glaw realizes that the perception of these animals is influenced by people's gardening in May. Due to the increase in garden activities, there are now numerous reports. Glaw's concerns are great: he is convinced that this vortex worm type is more widespread than previously known, and that many discoveries are still standing.

special features and dangers

The properties of the strudel worm are remarkable. When the worm is cut, it can regenerate and form new individuals. In addition, the kind of life forms such as earthworms and snails feeds. Another special feature is the secretion of poisonous mucus, which is associated with the tetrodotoxin nerve poison, which can be dangerous when contacted with open wounds. Pets should also refrain from eating the animals because there are reports on vomiting after consumption.

suspected ways of introducing

The exact reasons for the introduction of the whirlpool to Germany are still unclear. It is believed that the plant trade plays an important role. Customers could unknowingly take these animals into the garden when buying plants. However, the expert Glaw does not consider the situation to be alarming because the strudel worms are currently not considered to be invasive.

The discovery of this new species in Germany therefore not only causes interest, but also a certain concern of possible effects on domestic species and the environment.
