These structures are important in earthworms taxonomy and have been studied since the 19th century. More recently, Briones et al. (2008) suggested that their main function is to fix CO2. In Neotropical worms–(Rhinodrilidae and Glossoscolecidae)–calciferous glands have been studied primarily for their systematic value. Michaelsen proposed a classification system that defined at least seven morphological categories of calciferous glands for glossoscolecid genera.  aEarthworms  aGlanders  aGlossoscolecidae  aGlândula  aMinhoca  aGlossoscolex1 aFUKUDA, M.
