Senescence and Longevity of Sea Urchins. [PDF]

open access: yesGenes (Basel), 2020
Sea urchins are a minor class of marine invertebrates that share genetic similarities with humans. For example, the sea urchin species Strongylocentrotus purpuratus is estimated to have 23,300 genes in which the majority of vertebrate gene families are ...

Interaction among sea urchins in response to food cues [PDF]

open access: yesScientific Reports, 2021
Interaction among sea urchins remains largely uninvestigated, although the aggregation of sea urchins is common. In the present study, 1, 15 and 30 sea urchins Strongylocentrotus intermedius (11.06 ± 0.99 mm in test diameter) were placed in a 1 m2 ...

Biosynthesis of Polyunsaturated Fatty Acids in Sea Urchins: Molecular and Functional Characterisation of Three Fatty Acyl Desaturases from Paracentrotus lividus (Lamark 1816) [PDF]

open access: yesPLoS ONE, 2017
Sea urchins are broadly recognised as a delicacy and their quality as food for humans is highly influenced by their diet. Lipids in general and the long-chain polyunsaturated fatty acids (LC-PUFA) in particular, are essential nutrients that determine not

Lipidomic Profiling of Edible Japanese Sea Urchins by LC–MS [PDF]

open access: yesFoods
Sea urchins (Echinoidea) are marine echinoderms commonly consumed as seafood in East Asia. To date, various metabolic components of sea urchins have been analyzed, and their health benefits for humans have also been attracting attention.

Macroalgae and interspecific alarm cues regulate behavioral interactions between sea urchins and sea cucumbers [PDF]

open access: yesScientific Reports, 2022
Sea urchins and sea cucumbers are mutually beneficial organisms in kelp ecosystem. As herbivores, sea urchins process kelp through feeding and egestion, providing inaccessible food for benthic consumers such as sea cucumbers.

Species and Abundance of Sea Urchins (Diadematidae) on Different Environmental Pressure Conditions [PDF]

open access: yesJournal of Tropical Life Science, 2017
Genetic diversity of sea urchin are very high; there are no two organisms of the same species that are exactly alike. Dense aggregation of sea urchin is responsible for the destruction of marine algae communities on coral reef ecosystem.

The feces of sea urchins as food improves survival, growth, and resistance of small sea cucumbers Apostichopus japonicus in summer [PDF]

open access: yesScientific Reports, 2023
Mass mortality and low growth highly decrease the production efficiency and sustainable aquaculture development of the sea cucumber Apostichopus japonicus in summer. Sea urchin feces was proposed to address the summer problems.

Living in future ocean acidification, physiological adaptive responses of the immune system of sea urchins resident at a CO2 vent system

open access: yesScience of the Total Environment, 2019
The effects of ocean acidification, a major anthropogenic impact on marine life, have been mainly investigated in laboratory/mesocosm experiments.

Rearing Sea Urchins to Promote ‘Ready-to-Spawn’ Conditions for Ecotoxicological Surveys [PDF]

open access: yesToxics
The sea urchin Paracentrotus lividus is a good model in ecotoxicology, but adults living along the Italian coasts have a limited reproductive period.

Detrital kelp subsidy supports high reproductive condition of deep-living sea urchins in a sedimentary basin

open access: yesAquatic Biology, 2014
Highly productive kelp beds off Nova Scotia, Canada export detrital material to adjacent sedimentary habitats in deeper waters. We evaluated the importance of this subsidy to sea urchins Strongylocentrotus droebachiensis in less productive habitats ...
