Amphidromus cognatus is a special kind of large land snail. It's also known as the cognate land snail. This snail is `endemic` to `Australia`, which means it's only found there. It belongs to a group of snails called `camaenids`.
About the Snail's Shell
The Amphidromus cognatus snail has a big shell. Its shell can be from 21 to 33 millimeters long (about 0.8 to 1.3 inches). It's about 12 to 17 millimeters wide (0.5 to 0.7 inches).
The shell is usually bright yellow. Often, it has a brown band that spirals around the edge. The very top part of the shell might have a purplish color. The opening of the shell, called the lip, is usually light yellow or white.
Where It Lives
The Amphidromus cognatus snail has only been found in a small area in `Australia`'s `Northern Territory`.
Scientists first described this snail in 1907. They found three snails at `Port Essington` on the `Cobourg Peninsula` before 1850. However, no more snails have been found there since then. Between 1976 and 1980, people saw these snails again. They were found at one place on `Bathurst Island` and at three places on `Melville Island`.
Protecting This Snail
The Amphidromus cognatus snail is considered `Endangered` by the `IUCN`. This group works to protect nature around the world. Being "Endangered" means the snail is at a very high risk of disappearing forever.
The `Australian Government` does not list this snail as threatened. However, the `Northern Territory` government thinks it is `Vulnerable`. This means it's also at risk, but maybe not as immediately as "Endangered."
