Estimation of growth parameters for the exploited sea cucumber Holothuria arguinensis from South Portugal [PDF]
Understanding how species grow is critical for choosing appropriate fisheries management strategies. Sea cucumbers shrink during periods of aestivation and have naturally flaccid bodies that make measuring growth difficult.

SeeCucumbers: Using Deep Learning and Drone Imagery to Detect Sea Cucumbers on Coral Reef Flats
Sea cucumbers (Holothuroidea or holothurians) are a valuable fishery and are also crucial nutrient recyclers, bioturbation agents, and hosts for many biotic associates. Their ecological impacts could be substantial given their high abundance in some reef

Spatial distribution patterns and movements of Holothuria arguinensis in the Ria Formosa (Portugal) [PDF]
Holothurian populations are under pressure worldwide because of increasing demand for beche-de-mer, mainly for Asian consumption. Importations to this area from new temperate fishing grounds provide economic opportunities but also raise concerns ...

Origin of the holothurians (Echinodermata) derived by constructional morphology [PDF]
According to a recent hypothesis, the holothurians originated by a process of extreme paedomorphism as "giant larvae", with "de novo" developed radial systems.

Probabilistic ecological risk assessment for deep-sea mining: A Bayesian network for Chatham Rise, Pacific Ocean. [PDF]
Abstract Increasing interest in seabed resource use in the ocean is introducing new pressures on deep‐sea environments, the ecological impacts of which need to be evaluated carefully. The complexity of these ecosystems and the lack of comprehensive data pose significant challenges to predicting potential impacts.

Chiridota heheva—the cosmopolitan holothurian [PDF]
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.

In Situ Holothurian Noncontact Counting System: A General Framework for Holothurian Counting [PDF]
Holothurian counting is a basic requirement in aquaculture. An in situ noncontact approach for holothurian counting is basically harmless, which makes such techniques an optimal choice for aquaculture monitoring. To develop an in situ noncontact counting system, there are two main challenges.

Reproductive biology of the sea cucumber Holothuria sanctori (Echinodermata: Holothuroidea)
The reproductive biology of the sea cucumber Holothuria sanctori was studied over 24 months (February 2009 to January 2011) at Gran Canaria through the gonad index and a combination of macro- and microscopic analysis of the gonads.
