The kāhuli (Hawaiian tree snail) once inhabited forests across the Hawaiian Islands in abundant diversity and is recognized for its beautifully patterned shells and its ecological role grazing fungi from ʻōhiʻa leaves. Kāhuli are arboreal and sensitive indicators of forest health, able to reflect habitat changes and environmental degradation. Due to habitat loss, invasive predators, and climate change, many species are now critically endangered or extinct. Kāhuli also hold deep cultural significance, appearing in chants, legends, and lei traditions as symbols of longevity, fragility, and ancestral presence (U.S. Fish & Wildlife Service, Kupaa I Au, Island Conservation).
