Earthworms of different origin (tropical and temperate) and ecological category (endogeic, anecic and epigeic), individuals of the same species occupying different soils, and earthworms of different species from the same soil, have been studied. Intestinal mucus production suggests the existence of the mutualistic digestion system. The mucus percentage in the gut was greater in the epigeic than in both anecic and endogeic. Nevertheless, the relative enrichment was higher in the endogeic species. The organic matter content of the substratum seems to play a regulating role in the mutualistic system, because the greater the substratum organic matter content the lower the relative enrichment. Generally, in temperate zones more mucus was added to the substratum, suggesting that the low temperature do necessary a greater microflora simulation.
