In 1967, a South African worm was found by the side of a road in Williams Town that measured an incredible 6.7 meters (22 I. Microchaeta Rappi, Beddard (Lumbricus microchetus, Rapp), p.268, [19] Benham, Studies on Earthworms, Part II. The buccal region is a short, slightly protrusible, thin-walled section directly after the mouth that is theorised to have the function of exposing the muscular pharynx of M. rappi to food, allowing it to grasp and consume food with the pharynx directly. These worms collect food from above ground in the form of organic matter such as fallen leaves and drag them back underground to their burrows. I. Microchaeta Rappi, Beddard (Lumbricus microchetus, Rapp), p.269, [18] Benham, Studies on Earthworms, Part II.

Fetida translates roughly to foul-smelling, which is a reference to that bad-smelling liquid the worm produces when it is handled. Fossil evidence shows that earthworm-like creatures have been around for at least a half a billion years, surviving the mass extinction of animals about 65 million years ago that finished off the dinosaurs, among others. Earthworms have many adaptations that allow them to live underground successfully. These worms have been able to survive that conversion, despite the removal of the native vegetation. The African Nightcrawler can grow over 8 inches in length and is largest composting worm. According to research done at the Rothamsted Experimental Station, depending on soil quality, there can be anywhere from 250,000-1.75 million earthworms per acre of land. They live in the subsoil of blue, grey or red clay soils along stream banks and some south- or west-facing hills of their remaining habitat which is in Gippsland in Victoria, Australia. WebAfrican Night Crawler are a distinctive mix of a grey and purple color and grow to over twice the size of red worms, often reaching over 8 inches. Anecic is greek for out of the earth, because although these worms live below ground, they come up to soil level for their food. On this Wikipedia the language links are at the top of the page across from the article title. This is for two reason; first, because they cant allow the mucus on their skin to dry out or they will suffocate; second, because most also cant handle direct exposure to UV rays for more than a few minutes to an hour. Even if you dont mean any harm, this can be very harmful to them. It is also becoming a problem in some parts of Europe where it originated from. However, the average length of this species is approximately 1.8 m (6 ft) when naturally extended. It has not been spotted since around 1980. This is actually a major problem in forests such as in Rhode Island and Minnesota, which had previously been worm free since the ice age; with the arrival of the worm, it is changing the eco-system of these forests. Descriptions of New or Little-Known Earthworms. This worm is now commercially produced on a mass scale for use in composting. The clitellum and tubercula pubertatis exceptionally extended on numerous segments (from 10 to 34, or on some of these segments)[30]. Guinea worm was once widespread in Africa, the Middle East and many parts of Asia.

Poor quality soil will have closer to the 250,000 range; good quality soil, such as farm land, will have closer to the 1.75 million worms per acre. Guinea worm was once widespread in Africa, the Middle East and many parts of Asia. The knock-on effect of the presence of these worms is a threat to some plant species and microbial communities. Native worms, on the other hand, are enormously advantageous to our ecosystem and offer numerous benefits to our soils and plants. This physical alteration means that water and soluble nutrients can travel more easily down to the plant roots. On average Temperatures less than 60 F or greater than 86 F for extend periods of time can be fatal. It is semi-aquatic, living in swamps and mudflats in its native region of Louisiana. How long can an African Giant Earthworm reach? These worms are those that burrow vertically in the mineral layers of soil, creating permanent burrows as deep as six feet below surface level. The soil they were found in was described as impregnated with brackish water[3].
