Agassiz, 1880) is a regular deep-sea urchin from the family Echinothuriidae that has undergone numerous taxonomic changes throughout history. It is characterized by the presence of tridentate pedicellariae with spoon-shaped valves with a serrated edge. The geographic distribution of Hygrosoma petersii is extended to the Colombian Caribbean, as the southernmost record of the Caribbean Sea. Species description and, for the first time, Scanning Electron Microscopy (SEM) photographs of its pedicellariae and sphaeridia are presented, comparing it with its Caribbean congeners.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN Hygrosoma petersii (A. Agassiz, 1880) es un erizo regular de aguas profundas perteneciente a la familia Echinothuriidae, que ha sufrido numerosos cambios taxonómicos a lo largo de la historia. Se caracteriza por la presencia de pedicelarios tridentados con valvas en forma de cuchara con borde dentado. La distribución geográfica de H. petersii se extiende al Caribe colombiano, como el registro más austral del Caribe. Se presenta la descripción de la especie y por primera vez, las fotografías de Microscopía Electrónica de Barrido (MEB) de sus pedicelarios y esferidios, comparándola con sus congéneres caribeños.]]></p></abstract>
