The number of leeches has decreased worldwide and there is a great lack of knowledge about how common or unusual the leech is in the interior of Sweden. Now researchers want help from the public in gathering information from those who come across the bloodsucking animal, SVT Dalarna reports.
– This means that we can get a more complete picture of the blood lizard and try to understand where it is and why it is in one place, but not another, says Ulf Bjelke, from the Swedish University of Agricultural Sciences, to SVT.
He believes that blood lice have probably decreased because the number of cobwebs has decreased in Sweden.
– In many places where cows once grazed, there were leeches, but today there are no leeches. Now maybe it’s the moose next, Ulf Bjelke tells SVT.
A leech generally sucks blood from frogs and fish, but it can also suck blood from warm-blooded animals such as cows and elk. It is not dangerous for a person to be bitten, but the wound can bleed for a long time.
