Archachatina knorri is a large, air-breathing land snail endemic to Liberia, West Africa. Belonging to the family Achatinidae, it was first described in 1839 and remains relatively rare in captivity and poorly studied in the wild. This species is known for its robust shell, which may feature a red apex in some morphs, and its slow growth compared to other giant African land snails. In captive breeding, F1 and F2 generations have shown improved hardiness and stability, making them more accessible to dedicated keepers.
 
Wild populations are limited and fragile, with the IUCN listing A. knorri as Data Deficient due to a lack of comprehensive field studies. In nature, it likely plays a role in decomposing organic matter and maintaining soil health, though its exact ecological niche remains under-documented.
