Bulimulus lycodus

Unknown

Overview

Bulimulus lycodus is a species of tropical air-breathing land snail, a pulmonate gastropod mollusk in the subfamily Bulimulinae.

Bulimulus lycodus faces severe threats from habitat destruction and invasive species on its native Galápagos islands. Introduced mammals, particularly goats and pigs, have dramatically altered the vegetation structure and soil composition that this endemic land snail depends upon. Human development and tourism infrastructure have further fragmented the limited suitable habitat, while invasive plant species compete with native vegetation that provides essential food sources and shelter.

Threat summary

Habitat

This endemic Galápagos land snail inhabits dry coastal scrublands and rocky areas with sparse vegetation, typically found under stones and among leaf litter in areas with specific moisture and temperature conditions. It requires native plant communities that provide both food sources and the particular microhabitat conditions necessary for survival and reproduction.
