The bootlace worm is a ribbon worm that can be one of the longest animals known, with typical specimens measuring 5 to 15 metres. It lives along the coasts of northern Europe, including Britain, Norway and Denmark. Its thick, toxic mucus is its main defence.1

Hoe om dit te herken

It is usually only 5 to 10 millimetres wide, but it can grow very long.1
When handled, it produces large amounts of thick mucus with a faint, pungent smell, like iron or sewage.1

Gifkrag

Gif in sy vel

Sy vel is giftig. Dit is gevaarlik om aan te raak, te lek of te eet.

Wat doen sy gif as jy daaraan raak of dit eet?

The bootlace worm does not bite or sting, so it is poisonous rather than venomous. Its mucus contains a relatively strong neurotoxin, which attacks the nerves. The mucus is highly toxic, but tests showed low toxicity in human cells.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: LigSoos 'n bysteek of minder. Basies onskadelik vir mense.

No human injuries or deaths from this worm are known. Its mucus is highly toxic, so it is best not to touch it.1

Wat doen dit as dit bang is?

When handled, it releases large amounts of thick, toxic mucus, which it uses to deter predators.1

As iemand daaraan geraak of dit geëet het

Sit die wond in warm water, so warm as wat die persoon kan verdra sonder om te brand, en kry mediese hulp om die stekels te verwyder. Moenie self daarna grawe nie.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As jy daaraan geraak of dit geëet het: moenie jou oë of mond vryf nie, was jou hande en kry mediese hulp.

Dit is nie uit om jou te kry nie. Sy gif is net daar sodat niks dit eet nie. Meer oor veilig bly

Feite

In 1864, a specimen more than 55 metres long washed ashore after a severe storm near St Andrews, Scotland. It was longer than the lion's mane jellyfish.1

The bootlace worm is one of the longest known animals, and individuals have been recorded at up to 30 metres.1

Its mucus kills crabs and cockroaches in tests, and it could be used as an agricultural insecticide.1

Its body is very flexible and can stretch far beyond its usual length.1

Mite-breker

Mite: The bootlace worm regularly grows to over 55 metres long.

Waarheid: Reports of worms over 55 metres may be animals that were stretched. Ribbon worm bodies are flexible, so measurements should be treated with caution. Individuals are known to reach up to 30 metres.1
