Perdicella ornata is a species of tropical, tree-living, air-breathing, land snails in the family Achatinellidae. This species is endemic to Hawaii in the United States.

Description

Perdicella ornata has a shiny, acutely pyramidal shell with six margined whorls that reaches a height of approximately 1.48 cm. The shell's surface is patterned longitudinally with alternating white and black zigzags. The shell's lips are slightly thick at the edge, and the columella is broad and flattened.

Distribution and habitat

Perdicella ornata is endemic to the island of Maui, Hawaii. In 1853, it was found in the rainforest on Mt. Helu in western Maui, while another population was found in eastern Maui. In a small area, this unique species can be found in a deep ravine behind Lahaina, Hawaiian islands. It thrives in arboreal areas.

Conservation threats

Its global status is G1, indicating that it is critically endangered and at high risk of extinction. It was last reviewed on August 7, 1990. In 1982, only one population was reported from West Maui. Its national status is N1, indicating that it is in grave danger of extinction due to a small population and number of occurrences, a limited range, severe threats, and other aspects. Furthermore, the species' state status is S1, which has a comparable reason to G1. Threats to Hawaii's rare species of snail, Perdicella ornata, include over-collection, invasive predators such as Euglandina, Oxychilus, and rats.As well as destruction of habitat,that may be due to climate change. The preservation of these snails and their fragile ecosystems depends heavily on conservation efforts since it is said to be not managed and protected.In order to preserve populations, stop habitat loss, and lessen the effects of climate stress, advocacy for conservation and awareness-building and its importance are crucial. Because of the inspiration that Perdicella ornata's intricate shells provide for art, stories, history, culture, survival, creativity, cultural responsibility, and educational programs, protecting this species show us how stewards of the land and its communities we are.
