Microchaeta Rappi, Beddard (Lumbricus microchetus, Rapp), p.271, [25] Benham, Studies on Earthworms, Part II. Microchaetus rappi was first described in 1849 by Dr. Rapp as Lumbricus microchaetus[1] with an associated proposal for a new genus named Microchaetus (p. 31). Microchaetus rappi, the African giant earthworm, is a large earthworm in the Microchaetidae family, the largest of the segmented worms (commonly called earthworms). The diagnoses for both . What are B2B and B2C explain with examples? These giant earthworms average 1 metre (3.3 ft) long and 2 centimetres (0.79 in) in diameter and can reach 3 metres (9.8 ft) in length; however, their body is able to expand and contract making them appear much larger. In Pliskos 2013 article[29], she characterises M. rappi as having a large body size extending over one meter in length, sometimes over 2 meters, with characteristic external subdivision of preclitellar segments, [V-shaped] nephridial bladders and double dorsal blood vessels. Ending the digestive tract of M. rappi, the rectum allows for the excretion of waste. Were sorry, but GBIF doesnt work properly without JavaScript enabled.

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. Plisko states in her article that the broad description of the site was imprecise[4], and when originally described by Rapp, the recorded observations on the anatomy were very few[5]. 15. The tubular intestine widens into the thin-walled sacculated intestine in somite 12, further widening to about three times its previous diameter by the next somite. Near the front, the setae on the underside were longer and had a different form to setae over the rest of the body; the thickened region, usually about the middle in the ordinary setae, is just below the free end, giving the appearance of a spear-head[19].

Beddard described M. rappi as having extreme length that [was] difficult to state with certainty, with a dark green colouration which darkened to a duller green the further down the body. The circular muscular layer of M. rappi is thick and grouped into strands separated by connective tissue for form an oblique shape, and is layered in alternating circular and longitudinal muscles[24]. Microchaetus rappi used to rule the top of the longest worm. It averages about 1.4 m (4.5 ft) in length, but can reach a length of as much as 6.7 m (22 ft) and can weigh over 1.5 kg (3.3 lb).

Beddard made the same mistake in his 1895 study, where the differences between species described by himself and Benham (l886a,b) were ignored, and the position of the clitellum on 10-25 was indicated. This may be one of the discrepancies referred to in Pliskos 1999 paper, the differences in clitellum[16]. Notes on the status of the family Microchaetidae.
