Structure Elucidation of New Acetylated Saponins, Lessoniosides A, B, C, D, and E, and Non-Acetylated Saponins, Lessoniosides F and G, from the Viscera of the Sea Cucumber Holothuria lessoni

open access: yesMarine Drugs, 2015
Sea cucumbers produce numerous compounds with a wide range of chemical structural diversity. Among these, saponins are the most diverse and include sulfated, non-sulfated, acetylated and methylated congeners with different aglycone and sugar moieties ...

Genomic Characterization of a Novel Tenericutes Bacterium from Deep-Sea Holothurian Intestine

open access: yesMicroorganisms, 2020
Intestinal bacterial communities are highly relevant to the digestion, nutrition, growth, reproduction, and immunity of animals, but little is known about the composition and function of intestinal microbiota in deep-sea invertebrates. In this study, the

Sea Cucumber: New source of Protein for Human Consumption

open access: yesFrontiers in Marine Science, 2014
Aquaculture, probably the fastest growing food-producing sector, now accounts for nearly 50 percent of the world's food fish consumed by humans, and this share is expected to increase further to meet future demand.

Antibiotics Modulate Intestinal Regeneration

open access: yesBiology, 2021
The increased antibiotics usage in biomedical and agricultural settings has been well documented. Antibiotics have now been shown to exert effects outside their purposive use, including effects on physiological and developmental processes.

Chiridota heheva—the cosmopolitan holothurian [PDF]

open access: yesMarine Biodiversity, 2020
AbstractChemosynthetic ecosystems have long been acknowledged as key areas of enrichment for deep-sea life, supporting hundreds of endemic species. Echinoderms are among the most common taxa inhabiting the periphery of chemosynthetic environments, and of these, chiridotid holothurians are often the most frequently observed.

Novel Circular Single-Stranded DNA Viruses among an Asteroid, Echinoid and Holothurian (Phylum: Echinodermata). [PDF]

open access: yesPLoS ONE, 2016
Echinoderms are prone to large population fluctuations that can be mediated by pervasive disease events. For the majority of echinoderm disease events the causative pathogen is unknown.

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.
