Shells of Liguus fasciatus can reach a size of 42–68 millimetres (1.7–2.7 in). [6] [1] These polished shining shells, ranging from white to almost black, have whorls banded with many colors (chestnut, orange, yellow pink or green). [1]

These tree snails feed on fungus and algae scraped from the bark of the host plants (mainly wild tamarind ( Lysiloma latisiliquum ), pigeon plum ( Coccoloba diversifolia ) and Myrsine species). They can be found mainly from May through September, but they are active throughout the year. [1]

Distribution

This species is the most widespread of all the Liguus. It occurs in the Caribbean Area (South Florida. Florida Keys, North coast of Cuba, Isle of Pines). [1] [7]

Habitat

These tree snails can be found in southern Florida on hammocks, tropical forest and shrubs habitats that are slightly higher in elevation than the surrounding area. [1]
