They breed in the warmer months and produce egg capsules that are 4 centimetres (1.6in) to 7 centimetres (2.8in) in length which are laid in their burrows. I don't know exactly what fraction of the time of foragers are spent outside and I would suspect it would varies from species to species. Sperm-pores were not visible on the surface as there [were] no papillae or other marks but by tracing down the sperm duct [it was found] to end in somite [19][21]. I. Microchaeta Rappi, Beddard (Lumbricus microchetus, Rapp), p.274, [26] Benham, Studies on Earthworms, Part II. Given the sizes of other non-mammalian tetrapods and how few of them are burrowers whichever the largest underground animal is may well be a mammal. The Microchaetus rappi is the longest earthworm. 31-56. [5][6], Gippsland earthworm colonies are small and isolated,[7] and the species' low reproductive rates and slow maturation make those small populations vulnerable. He also described an increase in body thickness in somites 4-7, due to the thickness of the muscular layers of the body wall[15].
