When the bootlace worm is irritated, it releases large amounts of thick mucus that is poisonous for crustaceans.“We already know that peptide toxins are found in, for example, cone shells that live in tropical waters,” he said.“Bootlace worm live in colder waters, for example, the coastlines of Great Britain and Norway and the west coast of Sweden.”“This peptide toxin, named nemertide α-1, is the most poisonous substance to have been found in Sweden’s animal kingdom and the fact that it may be possible to use it makes the discovery even more exciting.”Toxins often affect the ionic channels, that is, proteins that control the transport of different ions in and out of cells.Professor Göransson’s team showed that the isolated toxin impedes the inactivation of the sodium channels in three species of invertebrate animals: the German cockroach, fruit fly and Laboratory tests were conducted to investigate how the toxin affects the sodium channels of mammals.

Moreover, the whole chain of research can be attributed to our team’s effort, from discovering the substance in the bootlace worm to describing the structure of the toxin and studying its effect.”

The bootlace worm (Lineus longissimus) is one of the longest known animals, with specimens up to 50 meters (160 ft) long and up to 10 centimeters (3.9 in) wide being reported. He didn’t feel much of anything. The bootlace worm is one of several hundred species of flat worms that belong to a group known as Nemertea.

Bootlace worms are free-living creatures which dwell on or in the sea floor, capturing prey with their proboscis. She has some worms in her lab that have chosen to eat no more than once in three to four years.Göransson proposes that their toxic mucus might make a useful defense.

There, the reaction was not nearly as strong.“Therefore, we believe nemertide α-1 is probably not poisonous for humans or other mammals,” the researchers said.“Today, similar neurotoxins that have been extracted from snakes, spiders and cone shells are used, for example, as pharmaceuticals, pharmacological tools, in biotechnology and as agricultural insecticides.”“We believe that the toxins from the bootlace worm can also be used to develop new insecticides.”“Nemertide α-1 has a very powerful effect on crustaceans and cockroaches, which is why it could serve as a very effective insecticide,” Professor Göransson said.“From a research point of view, it’s exciting to have discovered a new toxin in our own fauna, in a group of animals that has basically never been explored. There, he explores how animal poisons appear to have evolved.Unlike earthworms, the 1,300 or so species of bootlace — or ribbon — worms have no segments.
