Lanistes grasseti

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Lanistes grasseti faces significant pressure from habitat degradation in its freshwater environments, particularly through sedimentation and pollution of lake and river systems. Water level fluctuations and human activities around water bodies have altered the aquatic vegetation communities that this gastropod depends on for feeding and shelter. Agricultural runoff and urban development in watersheds have introduced chemical pollutants that affect water quality in its native range.

Threat summary

Habitat

This freshwater gastropod inhabits lakes, rivers, and associated wetland systems in East Africa, typically found among aquatic vegetation in shallow waters. It prefers areas with moderate water flow and abundant organic matter that supports its feeding on detritus and algae.
