An approach about internet trade in Brazil of live terrestrial and freshwater molluscs

Introduction: We present one first known assessment about of the biodiversity of land and freshwater molluscs (native and exotic introduced) involved in legal and clandestine trade activities developed in the vast Neotropical territory of Brazil, South America, principally by the ornamental aquarium trade sector. Objective: An initial general review of the legal and clandestine trade activities in Brazil envolving exotic introduced and native moluscs. Methodology: Based on the combination from wide bibliographical consultation, occasional visits to specialized stores, reception of data provided in a timely manner by informants and, mainly, through access to and monitoring of specific trade actions carried out through the social networks/ internet. Results: Were able to record a total of twenty-two (22) species, being fifteen (15) aquatic freshwater gastropod forms (12 operculated & 3 pulmonate -- 8 of them exotic introduced) and seven (7) terrestrial pulmonate snails -- 2 of them exotic introduced -- and 5 native of forestry habits, taxonomically distributed all in 10 genera, 9 families and 3 subclass. Conclusions: The purpose of this checklist is to provide a immediate and important reference source for future monitoring of this particular widely neglected sector in the country, while also aiming to contribute to the advancement advance towards the creation and organization of a more critical, appropriate and sustainable trade in these invertebrate animals.
