description Araeosoma violaceum Overview
*Araeosoma violaceum* is a species of deep-sea sea urchin classified within the family Echinothuriidae. Known for its distinct purplish hue, it inhabits the deep ocean floor. Members of this family are commonly known as leather urchins due to their flexible, soft tests, unlike the rigid shells of shallow-water species. This morphological adaptation allows them to withstand the intense hydrostatic pressure of their deep-water environment.
