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.

Species DiversityAn association comprising a solitary ascidian attached to the dorsal surface of a holothurian was discovered in 2022 on the bathyal seafloor (ca. 2000 m depth) of the western slope of the Chishima (Kuril-Kamchatka) Trench, off the southeastern coast of ...

Holothurian Nervous System Diversity Revealed by Neuroanatomical Analysis. [PDF]
PLoS ONE, 2016 The Echinodermata comprise an interesting branch in the phylogenetic tree of deuterostomes. Their radial symmetry which is reflected in their nervous system anatomy makes them a target of interest in the study of nervous system evolution. Until recently,

Carbonate sedimentology: An evolved discipline
The 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.

Metabolic rates are significantly lower in abyssal Holothuroidea than in shallow-water Holothuroidea [PDF]
Royal Society Open Science, 2018 Recent analyses of metabolic rates in fishes, echinoderms, crustaceans and cephalopods have concluded that bathymetric declines in temperature- and mass-normalized metabolic rate do not result from resource-limitation (e.g. oxygen or food/chemical energy)

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

IET 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.

Molecular mechanisms of fission in echinoderms: Transcriptome analysis. [PDF]
PLoS ONE, 2018 Echinoderms are capable of asexual reproduction by fission. An individual divides into parts due to changes in the strength of connective tissue of the body wall.

Diversity and antimicrobial potential in sea anemone and holothurian microbiomes. [PDF]
PLoS ONE, 2018 Marine invertebrates, as holobionts, contain symbiotic bacteria that coevolve and develop antimicrobial substances. These symbiotic bacteria are an underexplored source of new bioactive molecules to face the emerging antibiotic resistance in pathogens ...
