What is the biggest species of earthworm in the world?
The longest known earthworm in the world, stretching to more than 2m, is the Australian Giant Gippsland earthworm Megascolides australis. Sadly, this giant is listed as a vulnerable species under the The Environment Protection and Biodiversity Conservation Act 1999.
Where are earthworms found?
Earthworms can be found in almost all areas of the globe and in all sorts of habitat: tropical rainforests, on mountains, in the branches of trees, and even in birds’ nests. The exception is extreme deserts.
Are all earthworms the same colour?
Some Asian species, which can sometimes survive as small populations in UK greenhouses, have a beautiful blue green iridescence. These worms can also jump!
Microscolex phosphoreus, which can glow, is occasionally found here – often on golf courses, where it annoys the golfers by producing tiny casts.
The ‘fried egg worm’ in the Philippines is so named because it appears to have tiny fried eggs along its body.
Are there any earthworm events?
Highlights of the worm enthusiast’s calendar include:
Blackawton International Worm Charming Festival, Devon
Teams are challenged to persuade as many worms as possible to come to the surface without digging. See http://bit.ly/1ieCr1N
Cordova Iceworm Festival, Alaska
This festival celebrates the iceworm Mesenchytraeus solifugus. This small oligochaete worm lives in the ice; it has a type of antifreeze within it and feeds on bits of algae. The next event is February 1 – 5, 2017. See http://bit.ly/2iV4lpo
The Karmai Giant Worm Festival, Korumbarra, Australia
Running for 20 years, this festival probably saved the town from economic collapse after the local mine closed in the 1970s. Korumbarra falls within the territory of the Giant Gippsland earthworm (see above), and decided to celebrate its local hero.
Both the festival and its star, a 100-metre-long worm puppet, were named Karmai after the Aboriginal word for earthworm. This extraordinary story is celebrated by Melita Rowston’s Giant Worm Show at the Fringe in Adelaide and Syney during 2017. See http://bit.ly/2j95maW
