Laminella sanguinea is a species of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Amastridae. This species is endemic to the Hawaiian Islands. This species is ground-dwelling and often has debris on its shell to camouflage itself. ^{[2] [3]}

Description

Laminella sanguinea, possesses a solid, thin calcareous shell which measures about 2 centimeters in length. ^[4] The cone-shaped shell has a distinctive zigzag pattern that resembles the Kike'eke'e kapa pattern and is commonly found covered in feces, which is said too help them camouflage. ^{[2] [3]} The base of the shell starts off a brownish-red tint and slowly transitions into a tan color at the tip. ^[5] Its slimy and squishy body is a translucent grey and has the ability to retract into its shell. ^[5]

Distribution

Habitat

Laminella sanguinea, currently resides in a habitat dominated by Freycinetia arborea (i`e i`e) along rocky and craggy areas in several locations in the Wai`anae  Mountains. ^{[5] [3]} This species is extremely rare and can be usually found in the trees and on the ground where it nourishes on dead and decaying leaf material. ^{[5] [3]} They are threatened by invasive predators ( Euglandina, rats, Oxychilus ), habitat destruction, and over collecting. ^{[5] [3]}
