Micromechanics of Sea Urchin Spines [PDF]
PLoS ONE, 2012 The endoskeletal structure of the Sea Urchin, Centrostephanus rodgersii, has numerous long spines whose known functions include locomotion, sensing, and protection against predators. These spines have a remarkable internal microstructure and are made of single-crystal calcite.

Bioerosive impact of Diadema mexicanum on southern Mexican Pacific coral reefs
Ciencias Marinas, 2016 Reef ecosystem growth and maintenance is closely related to sea urchin feeding activities. Hence, quantifying the bioerosive capacity of the sea urchin Diadema mexicanum is necessary to evaluate its impact on coral communities and reefs that develop off

Eutacticity in Sea Urchin Evolution [PDF]
Bulletin of Mathematical Biology, 2007 An eutactic star, in a n-dimensional space, is a set of N vectors which can be viewed as the projection of N orthogonal vectors in a N-dimensional space. By adequately associating a star of vectors to a particular sea urchin we propose that a measure of the eutacticity of the star constitutes a measure of the regularity of the sea urchin. Then we study

Ocean warming alters predicted microbiome functionality in a common sea urchin
Proceedings of the Royal Society B: Biological Sciences, 2018 The microbiome of sea urchins plays a role in maintaining digestive health and innate immunity. Here, we investigated the effects of long-term (90 day) exposure to elevated seawater temperatures on the microbiome of the common, subtropical sea urchin ...

Gastrulation in the sea urchin
, 2020 Gastrulation is arguably the most important evolutionary innovation in the animal kingdom. This process provides the basic embryonic architecture, an inner layer separated from an outer layer, from which all animal forms arise. An extraordinarily simple and elegant process of gastrulation is observed in the sea urchin embryo. The cells participating in

Sequencing and analysis of the gastrula transcriptome of the brittle star Ophiocoma wendtii [PDF]
, 2012 Background The gastrula stage represents the point in development at which the three primary germ layers diverge. At this point the gene regulatory networks that specify the germ layers are established and the genes that define the differentiated states ...

A phylogenomic resolution of the sea urchin tree of life
BMC Evolutionary Biology, 2018 Echinoidea is a clade of marine animals including sea urchins, heart urchins, sand dollars and sea biscuits. Found in benthic habitats across all latitudes, echinoids are key components of marine communities such as coral reefs and kelp forests. A little
