Etymology

The term 'echinoderm' comes from the Greek words โ€˜echinosโ€™, meaning 'spiny', and โ€˜dermaโ€™, meaning 'skin'. First used in scientific literature in the mid-19th century, it reflects the unique features of these animals, particularly their spiny exterior. Echinoderms represent one of the major phyla of the animal kingdom and are known to date back to the Cambrian period, making them one of the oldest groups of animals in existence today. Their evolutionary lineage is significant in understanding the development of vertebrates, as they share a common ancestry. Over time, the classification and study of echinoderms have developed, leading to the recognition of their ecological importance in marine environments.
