Structural Characterization and Profiles of Saponins from Two Algerian Sea Cucumbers
MoleculesSea cucumbers are benthic marine invertebrate members of the phylum Echinodermata. Due to the absence of a rigid skeleton, these species have developed chemical defenses based on the production of saponins (triterpene glycosides).

Zoologica Scripta, Volume 55, Issue 4, Page 639-651, July 2026.ABSTRACT Hadal environments (> 6000 m ocean depths) are often viewed as isolated locations with high species endemism due to limited dispersal. However, molecular studies continue to reveal greater complexity that questions historical perceptions. Recent population genetic studies focused on scavenging amphipods have identified broadly distributed ...

Journal of Biogeography, Volume 53, Issue 6, June 2026.ABSTRACT Aim The biogeography and evolution of South African sea cucumbers have been previously explored; however, these aspects lack detailed study. This study (1) explores the biogeography of sea cucumbers along the coastline of South Africa (SA) and (2) presents a preliminary molecular phylogeny based on the mitochondrial 16S marker.

Recruitment patterns of 2 sea cucumber species in a Central Mexican Pacificcoral reef community
Revista Mexicana de Biodiversidad, 2016 Holothurians are nutrient recyclers, bioturbators, and prey for other taxa in diverse marine ecosystems; thus, they directly impact the distributionof organisms with which they are associated.

Free Sterol Composition of Deep-Sea Holothurian cf.
Natural Product Communications, 2022 The free sterol fraction from the deep-sea holothurian Orphnurgus cf glaber Walsh, 1891, has been isolated and studied by GC–MS. Sterols containing Δ 7 , Δ 0 , Δ 5 , polyunsaturated and 5,8-epidioxy modified cores were found.

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.Abstract The Rowley Shoals, off northwestern Australia, are renowned as a biodiversity hotspot. This remote system comprises three atolls, Clerke, Imperieuse and Mermaid, which in recent years have been increasingly targeted by illegal fishing, a pressure rising across the Indo‐Pacific.
