True limpets of the order Patellogastropoda are key near-shore marine benthic elements of inter- and sub-tidal rocky ecosystems. The Nacellidae includes two genera, Cellana and Nacella, with markedly disjoint distributions in the Indo-Pacific and the Southern Ocean, respectively. Cellana includes more than 35 species and several subspecies distributed in tropical and warm-temperate waters across Indo-Pacific. In general, nacellid limpets exhibit short larval lifespan (< 20 days) compared to other gastropods. In spite of these short larval lifespan, several nacellids are endemic to isolated islands. Across the Southern Hemisphere, Cellana expands its distribution to several Pacific Islands including those from Micronesia, Melanesia, and Polynesia. The eastward distribution of the genus includes the Juan Fernández Archipelago, located ~ 700 km off the coast of Chile and more than 6000 km from its closest relatives currently found in the Marquesas and Austral islands.
