چکیده
Seven species of holothurians of the family Psychropotidae were collected during the cruise D300 of RRS Discovery to Crozet plateau. Three of them, Benthodytes wolffi, Psycheotrephes discoveryi and Psychropotes xenochromata are described as new to science. One species, Benthodytes abyssicola Théel, regarded recently as incertae sedis, is redescribed with designation of a lectotype. Additional notes are provided to descriptions of Psychropotes scotiae (Vaney) known from two specimens and Psychropotes longicauda Théel, the cosmopolitan highly variable species.

A new genus and species of laetmogonid holothurian (Elasipodida, Laetmogonidae), collected from around the Crozet Plateau in the Southern Indian Ocean, is described. It differs from other members of the family in that the body wall lacks the wheel-shaped calcareous deposits completely. Instead only rods are present. The genus is also distinguished by the combination of other morphological chara...

BACKGROUND There is growing interest in mining polymetallic nodules from the abyssal Clarion-Clipperton Zone (CCZ) in the tropical Pacific Ocean. Despite being the focus of environmental studies for decades, the benthic megafauna of the CCZ remain poorly known. In order to predict and manage the environmental impacts of mining in the CCZ, baseline knowledge of the megafauna is essential. The AB...
