Benham reported that the exterior of his specimen was in colour, a beautiful iridescent, greenish brown dorsally and laterally, whilst ventrally it is of a pink tint [14]. The worm lived in the sea 400 million years ago and is estimated to have been up to two metres long. eight species remained: microchaetus, papillatus, rappi, decipiens, braunsi, kloperi, stuckenbergi and vernoni.  However, the average length of this species is approximately 1.8 m (6 ft) when naturally extended. Organisms classified as Microchaetus rappi have excretory system holonephric; nephropores present; only one gizzard present, in segment 7 testes and male funnles in other than proandric arrangement testes and male pores in holandric arrangement; nephiridial bladders V-shaped spermathecae always prosterior to testis locations [11].

Ending the digestive tract of M. rappi, the rectum allows for the excretion of waste. The soil they were found in was described as impregnated with brackish water[3]. Note also that most ant casts spend most of their time underground in the nest. Microchaetus rappi has a history of confusion as being synonymous with M. The researchers claim that this case of unicoloniality cannot be explained by loss of their genetic diversity due to the genetic bottleneck of the imported ants. This may be one of the discrepancies referred to in Pliskos 1999 paper, the differences in clitellum[16]. Ending the digestive tract of M. rappi, the rectum allows for the excretion of waste.

Where is the worlds largest bootlace worm? 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]. str.) Why are certain animals much much bigger than other ones? microchaetus. I. Microchaeta Rappi, Beddard (Lumbricus microchetus, Rapp), p.268, [19] Benham, Studies on Earthworms, Part II. 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. I. Microchaeta Rappi, Beddard (Lumbricus microchetus, Rapp), p.276, [29] Plisko, J. In 1864, following a severe storm at St Andrews in Fife, UK, a record-breaking specimen was washed ashore, and was found to measure over 55 m (180 ft) long.

Reynolds, J. W., and D. G. Cook, 1993: Nomenclatura oligochaetologica. The digestive tract of M. rappi consists of: the buccal region, the pharynx, esophagus, gizzard, tubular intestine with gland, sacculated intestine, and rectum[25]. Further comparison of specimens at the British Museum of Natural History (BMNH) by Plisko showed that although Beddard's (l886a,b) comprehensive description of rappi clearly distinguishes it from microchaetus, other data supplied later by Beddard (1895) include characters for both rappi and microchaetus.[34].

Leading from the gizzard to the sacculated intestine, the tubular intestine is cylindrical and is lined with a thick, muscular wall and longitudinal ridges[27]. This may be one of the discrepancies referred to in Pliskos 1999 paper, the differences in clitellum[16]. I. Microchaeta Rappi, Beddard (Lumbricus microchetus, Rapp), p.270, [24] Benham, Studies on Earthworms, Part II.
