Rare cactus plant, with a greenish-gray globose stem, which over time tends to take on a cylindrical shape. This species is distinguished from other Copiapoa for its much longer and thinner white thorns that completely cover the plant. It has multiple well-defined ribs, with white fluffy areoles. Flowering occurs rarely and only in mature specimens, generating yellow funnel-shaped flowers.
