Helicostyla smargadina
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Helicostyla smargadina faces severe population decline primarily due to extensive deforestation and habitat conversion throughout its limited range in the Philippines. Agricultural expansion and urban development have fragmented the remaining forest patches where this endemic land snail occurs. Over-collection for the shell trade and introduction of invasive species further compound the threats to this critically endangered gastropod.
Habitat
This endemic Philippine land snail inhabits tropical rainforest environments, typically found in the leaf litter and understory vegetation of primary and secondary forests. The species requires humid microhabitats with stable moisture levels and organic debris for feeding and shelter.
