Description

Annette's cowrie is a medium-sized, glossy seashell with an ovate shape. Its dorsal surface is characterized by a mottled pattern of rich brown or reddish-brown blotches and spots on a lighter, often cream or pale tan background. The base is typically lighter, cream to pale orange, and features distinct dark brown spots along the margins. The aperture is long and narrow, lined with prominent, fine teeth, and the interior of the aperture often displays a purplish hue.
