Holothurian Fucosylated Chondroitin Sulfate [PDF]

open access: yesMarine Drugs, 2014
Fucosylated chondroitin sulfate (FucCS) is a structurally distinct glycosaminoglycan found in sea cucumber species. It has the same backbone composition of alternating 4-linked glucuronic acid and 3-linked N-acetyl galactosamine residues within disaccharide repeating units as regularly found in mammalian chondroitin sulfates.

Assessing microplastic ingestion and occurrence of bisphenols and phthalates in bivalves, fish and holothurians from a Mediterranean marine protected area [PDF]

open access: yes, 2022
Microplastic (MP) ingestion, along with accumulated plasticizers such as bisphenol A (BPA), bisphenol F (BPF), and bisphenol S (BPS), and phthalates represented by diethyl phthalate (DEP), dibutyl phthalate (DBP) and bis (2-ethylhexyl) phthalate (DEHP ...

Untargeted Metabolomics Reveals Seasonal and Tissue‐Specific Metabolic Shifts in Holothuria cinerascens

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Untargeted metabolic profiling of three body tissues from Holothuria cinerascens in South Africa using 1H‐NMR and UPLC–QTOF–MS revealed distinct tissue‐specific and seasonal metabolic variations, with the body wall and gut/mesentery exhibiting high metabolite diversity.

Carbonate sedimentology: An evolved discipline

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Systematics, biology, ecology And zoogeography of holothurians: Ecology of commercially important Holothurians of India [PDF]

open access: yes, 1994
A knowledge of the ecology of holothurians is important for proper exploitation of the resource. Species like Holothuria (Metriatyla) scabra, Holothuria (Thelothuria) spinifera are distributed on sandy beds with algae in shallow waters.

CCFF‐Net: Cross‐Channel Feature Fusion Network for Underwater Object Detection

open access: yesIET Image Processing, Volume 20, Issue 1, January/December 2026.
Challenging underwater environmental conditions lead to severe degradation of underwater images, such as intensity attenuation and colour distortion. This issue causes incomplete feature representation of underwater objects, posing difficulties to state‐of‐the‐art detectors.

Chemical Defense Mechanisms and Ecological Implications of Indo-Pacific Holothurians

open access: yesMolecules, 2020
Sea cucumbers are slow-moving organisms that use morphological, but also a diverse combination of chemical defenses to improve their overall fitness and chances of survival.

YOLOViT‐DETECT: A Hybrid Approach for Real‐Time Fish Species Detection and Classification in Aquaculture

open access: yesIET Image Processing, Volume 20, Issue 1, January/December 2026.
We propose YOLOViT‐DETECT, a hybrid model combining an enhanced YOLOv8 with a spatial attention module for fish detection and a ViT‐B/16 transformer for species classification. The method achieves high accuracy in challenging underwater environments, outperforming standalone models.
