Potamopyrgus antipodarum slugs are no different from pencil heads, but they are spreading rapidly from New Zealand to Asia and the Americas, attacking native snails elsewhere.

What makes this small mud snail become a powerful invader? The answer lies in their rapid fertility. Females can produce up to 230 descendants each year and especially do not need males.

And the researchers have found that the slug can survive without water for two days, meaning they can snuggle on the bird's body, fishing equipment or terrestrial animals to get to the territory. new.

Spanish experts Alvaro Alonso and Pilar Castro-Diez of Alcala University drew their conclusions when conducting experiments on New Zealand slugs, according to a report on NeoBiota.

With the above information, scientists have given some advice to prevent the spread of this species. For example, fishing gear needs to be dried for at least 50 hours continuously if fishermen often operate in different waters.
