Newcombia canaliculata is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinellidae. This species is endemic to Hawaii.
Taxonomy
The Newcombia genus is divided into three series: [2]
- Newcombia plicata
- Newcombia philippiana
- Newcombia cumingi
Distribution & Habitat
These mollusks have been found in the Hawaiian Archipelago, on Halawa, Molokai and Wailau, Maui. [3] Though rarely seen, they can be found resting at higher, mesic elevations. Commonly they camouflage as pieces of a tree branch. [4] They live on lehua trees, as well as lantana trees. [5]
Description
Newcombia canaliculata has a long, sinistral, thin textured spiral shell, made up of calcium carbonate that ranges in varieties of brown tones. [5] Shells may be solid colors completely, or have multiple tinges/patterns of neutral colors like white, black and brown. What makes the Newcombia canaliculata so unique is its thin spiral ribbing coiled around the shell. [5] Additionally some snails may have zigzag patterns on a single whorl and oftentimes appear “blurred.” [5]
Conservation
Newcombia canaliculata on the IUCN Red list as critically endangered. They were recently thought to be extinct until a recent discovery on the island of Molokai. [6]
Threats
These mollusk are at risk to predation by rats ( Rattus rattus, Rattus exulans, and Rattus nowegicus) and Chameleons ( Chamaeleo jacksonii). Predation as well as low reproductive rates and inbreeding are all threats to Newcombia canaliculata. [6]
