A new species of brooding Psolidae (Echinodermata: Holothuroidea) from deep-sea off Argentina, Southwestern Atlantic Ocean
This paper describes a new species of Psolus (Holothuroidea, Echinodermata), P. lawrencei sp. nov., (19 specimens) found in the deep sea (308–1398 m) in the Southwestern Atlantic Ocean (SWAO) (around 38°S–54°W) with brooders (up to 3.15 mm) in the tentacles of females and a penis-like genital papilla on males.

متن کاملPhylogeny of Holothuroidea (Echinodermata) inferred from morphology
Holothuroids, or sea cucumbers, are an abundant and diverse group of echinoderms with over 1400 species occurring from the intertidal to the deepest oceanic trenches. In this study, we report the first phylogeny of this class, based on a cladistic analysis of 47 morphological characters. We introduce several previously unconsidered synapomorphic characters, examine the relationships between rep...
