Distinctive large holothurian with sail, close morphological match to Psychropotes semperiana from Théel 1882 (Fig. 18).

Genetic data for this taxa with new GenBank accession numbers are provided in Table 2


Forms a unique monophyletic clade distinct from other AB01 specimens and no match to any GenBank or BOLD databases. Morphologically consistent with Psychropotes semperiana Théel, 1882. The type locality of Psychropotes semperiana is Atlantic (5°48'N; 14°20'W, 4500m depth) and we use the tentative name Psychropotes cf. semperiana for this material until we have a better understanding of genetic variation within the species including data from the type locality.


Observed moving on the seabed amongst polymetallic nodules.
