Conteúdo: 	There are approximately 288 known species of earthworms in Brazil although 800 to > 2000 species are estimated to exist, placing Brazil as number one in the biodiversity of this ecologically important invertebrate. At present, most species (87%) are native and only 13% are exotic, invasive worms. Most of the native species show a restricted distribution and high enmicity, while exotic species have extensively colonized mostly disturbed habitats. One species (Pontoscolex corethrurus), native to N Brazil, should be considered invasive, as it has spread throughout the country and is the most abundant and well-known Brazilian earthworm. There more than 40 species of giant (>30 cm lenght,> 1cm diam.) earthworms (minhocuçus) in Brazil. Several are harvested and widely commercialized as fish bait. Although prohibited, many families derive their income from worm harvesting and one species is on the IUCN endangered list; others may also be endangered. Due to their importance for soil properties and processes and services to natural and agricultural ecosystems, conservation and sustainable use of these invertebrates is an imperative. Nevertheles, this is hampered by the lack of knowledge of their biology and ecology as well as the lack of trained taxonomists and earthworm researches in Brazil.
