The Newcombia canaliculata is a special kind of air-breathing land snail. It's a type of mollusk that lives on land, found only in Hawaii. This makes it an endemic species, meaning it naturally lives nowhere else in the world.

Where Does This Snail Live?
These unique snails have been found on the Hawaiian Archipelago, specifically on the islands of Molokai (in a place called Halawa) and Maui (in Wailau).
Even though they are rarely seen, you might find them resting in higher, mesic areas. Mesic means these places have a balanced amount of moisture, not too wet and not too dry. These snails are masters of disguise! They often blend in perfectly, looking just like pieces of a tree branch. They like to live on lehua trees and also on lantana trees.
What Does the Newcombia canaliculata Look Like?
The Newcombia canaliculata has a long, thin, spiral shell. It's made of something called calcium carbonate, which is the same material as chalk or eggshells. The shell usually comes in different shades of brown.
Some shells are a solid color, while others have cool patterns or mixes of neutral colors like white, black, and brown. What makes the Newcombia canaliculata so special is the thin, spiral ribs that coil all around its shell. Some snails even have zigzag patterns on a single whorl (a full turn of the spiral). These patterns sometimes look a bit "blurred."
Why Is This Snail in Danger?
The Newcombia canaliculata is on the IUCN Red List as Critically Endangered. This means it's at a very high risk of disappearing forever. For a while, people thought these snails were extinct, meaning they had all died out. But then, they were excitingly rediscovered on the island of Molokai!
What Threats Does the Snail Face?
These snails face several dangers. They are hunted by rats, including the black rat, the Polynesian rat, and the Norway rat. Chameleons, especially Jackson's chameleons, also prey on them.
Besides being hunted, the Newcombia canaliculata also has trouble reproducing. They have low reproductive rates, meaning they don't have many babies. Also, inbreeding (when closely related animals have babies together) can make their population weaker. All these things make it hard for the Newcombia canaliculata to survive and grow its numbers.
