Bioeconomic modeling for a small-scale sea cucumber fishery in Yucatan, Mexico.
PLoS ONE, 2018 Due to the heavy exploitation of holothurians over the last few decades, it is necessary to implement fishing regulations aimed at reversing this situation. Holothurians require specific regulations that take into account their biology and ecology. Their

Proteases from the regenerating gut of the holothurian Eupentacta fraudatrix. [PDF]
PLoS ONE, 2013 Four proteases with molecular masses of 132, 58, 53, and 47 kDa were detected in the digestive system of the holothurian Eupentacta fraudatrix. These proteases displayed the gelatinase activity and characteristics of zinc metalloproteinases.

Deep-sea holothurians (Echinodermata, Holothuroidea) from the Colombian Southern Caribbean Sea [PDF]
Check List, 2020 Fifteen morphotypes of deep-sea holothurians were documented by photography or videography at depths of 596–2,566 m, using Remote Operated Vehicles (ROV) video surveys and towed camera transects, during hydrocarbon exploratory activities in the

Remote Sensing in Ecology and Conservation, EarlyView.This research established a new object detection model based on YOLOv11 to recognise benthic organisms, specifically sea cucumbers, by utilising high‐resolution photogrammetric‐based orthomosaics acquired along infralittoral Mediterranean Sea beds. The model demonstrated impressive performance metrics and, when combined with the Deepness plugin for the

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.Brachiopods are able to repair drill holes made in their shells by predatory gastropods. However, in most samples examined, drill hole repair is rare to absent: Presumably the drilling attack is usually fatal to the prey. The shells of short‐looped brachiopod Abyssothyris wyvillei, from deep‐sea dredge samples from two localities in the Tasman Sea, New

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).

Frontiers in Physiology, 2018 Research into the effects of reduced pH caused by rising CO2 on echinoderms has been strongly biased toward those groups which rely heavily on calcification, such as sea urchins.

Chiridota heheva—the cosmopolitan holothurian [PDF]
Marine 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.

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.ABSTRACT There is growing interest in the co‐culture of macroalgae and filter‐feeding bivalves due to anticipated trophic benefits that may enhance the productivity of both organisms. Detritus from cultured macroalgae has the potential to supplement bivalve diets, yet few studies have directly examined this relationship in co‐culture systems.
