Appalachina chilhoweensis, also known as the queen crater, is a species of pulmonate land snail in the family Polygridae. It is the largest North American land snail found east of the Rocky Mountains.[3] It is named after Chilhowee Mountain.[4]
Physical appearance
[edit]The queen crater is a large snail, with a shell ranging from 26.5 to 42 mm (1.04 to 1.65 in) in diameter. The base of the shell is yellow-brown in color, with dark-brown splotches and a pale, broad lip.[5]
Ecology
[edit]The queen crater is endemic to the southeastern United States, being found in Tennessee, Kentucky, and North Carolina.[1] It is fairly common in Tennessee, and its populations are considered secure. However, in Kentucky and North Carolina, where the species is considerably rarer, it is listed as imperiled.[1]
The queen crater is most commonly found in mixed upland hardwood forests, high up in the Appalachian mountains.[1][5] They typically reside on wooded hillsides or slopes, under leaf litter or on or around sandstone talus.[6] The highest elevation a queen crater has been recorded at is 1,666 meters, or 5,465.88 feet.[7]
