Predation of Oligochaeta by the exotic invasive snail Tanychlamys indica (Gastropoda, Ariophantidae) and expansion of the invasive species' distribution in Brazil

Key Points

• The aim is to investigate the impact of the invasive snail Tanychlamys indica on Oligochaeta populations and its expansion in Brazil.
• Field observations of Tanychlamys indica predation on Oligochaeta
• Mapping distribution of invasive snail species
• Analysis of ecological impacts
• Significant predation of Oligochaeta by Tanychlamys indica was observed.
• Expansion of Tanychlamys indica's distribution across various regions in Brazil was noted.
• Predation may threaten local Oligochaeta communities.
