Granata cumingii is a species of small to medium-sized sea snail, a marine gastropod mollusc belonging to the family Chilodontidae. It is characterized by its distinctive shell morphology and is found predominantly in the Indo-Pacific region.

The species was first scientifically described by A. Adams in 1850. Over time, it has been referred to by various scientific names, and synonyms include Stomatella cumingii A. Adams, 1850, and Euchelus cumingii (A. Adams, 1850). The genus Granata itself was established by Cotton & Godfrey in 1934.
Description The shell of Granata cumingii is typically depressed or flattened, giving it a somewhat discoidal or limpet-like appearance, though it retains a coiled structure. It generally measures up to a few centimeters in diameter. The exterior surface can range from relatively smooth to sculptured with fine spiral striae or granulations. A prominent feature is its relatively wide and often deeply open umbilicus (the central cavity on the underside of the shell). The aperture (shell opening) is wide, often giving the animal ample space to extend its foot. Shell coloration is often drab, including shades of white, cream, grey, or light brown, sometimes with subtle patterns or streaks. The nacreous (pearly) layer is often visible inside the aperture, particularly on the inner lip and columella.
Distribution and Habitat Granata cumingii is widely distributed throughout the Indo-Pacific biogeographic region, encompassing a vast area from the eastern coast of Africa to the central Pacific Ocean. It inhabits marine environments, typically found in subtidal zones on various substrates such as rocky reefs, coral rubble, and sandy areas. It occurs from shallow intertidal or subtidal waters down to moderate depths. Like other members of the Chilodontidae family, it is likely an herbivore or detritivore, grazing on microalgae and detritus found on the substrate.
