Trophic Requirements of the Sea Urchin Paracentrotus lividus Varies at Different Life Stages: Comprehension of Species Ecology and Implications for Effective Feeding Formulations

Frontiers in Marine Science, 2022
Investigations on trophic requirements of different life cycle stages of Paracentrotus lividus are crucial for the comprehension of species ecology and for its artificial rearing.

Morphological and Morphometric Characterisation of Selected Camarodont Sea Urchin (Echinoidea: Camarodonta) Pedicellariae (Paracentrotus lividus, Psammechinus miliaris and Echinus esculentus)

Acta Zoologica, EarlyView.
ABSTRACT Pedicellariae are small appendages on the surface of the echinoid test, involved in defence, cleaning, and locomotion. Pedicellariae in three species of camarodont sea urchins common in UK waters (Paracentrotus lividus [Lamarck, 1816], Psammechinus miliaris [P.L.S Müller, 1771] and Echinus esculentus [Linnaeus, 1758]) are the focus of this ...

Separating Faces in ARMS Metabarcoding Improves Marine Biodiversity Monitoring: A Comparison Across Protocols, Experimental Designs and Photographic Surveys

Molecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT Monitoring marine biodiversity requires approaches capable of capturing its spatial and temporal complexity. DNA metabarcoding coupled with Autonomous Reef Monitoring Structures (ARMS) is increasingly used for this purpose, yet most applications still pool all sessile fractions and rarely benchmark molecular outputs against photographic ...

Thermal Plasticity Supports Translocation of Wild Paracentrotus lividus to Recover Overexploited Populations

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT The gonads of the purple sea urchin Paracentrotus lividus are considered a delicacy in some European countries. Combined with rising international demand, their harvesting has become unsustainable in most regions. Despite recent fishing bans and seeding programmes using juveniles reared in hatcheries, challenges such as poaching, the long time

The thermal responses of barren‐forming urchins: Common patterns and knowledge gaps

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract As climate change accelerates, there is increasing need to understand how species and ecosystems respond to warming. The challenge we face is the huge diversity of responses among species, and their variability across biological, temporal, and spatial scales.

PROPOSAL OF SANITARY MANAGEMENT OF EDIBLE ECHINODERMS IN SARDINIA

Italian Journal of Food Safety, 2011
Sea urchin (Paracentrotus lividus) is an edible echinoderm very common in the Mediterranean sea. In the Sardinian gastronomic tradition it represents a product very used in some periods of the year, but in practice the sanitary controls by the competent ...
