Antero-posterior patterning in the brittle star Amphipholis squamata and the evolution of echinoderm body plans [PDF]
EvoDevoAlthough the adult pentaradial body plan of echinoderms evolved from a bilateral ancestor, identifying axial homologies between the morphologically divergent echinoderms and their bilaterian relatives has been an enduring problem in zoology.

Species richness and distribution patterns of echinoderms in the southwestern Atlantic Ocean (34-56°S) [PDF]
Scientia Marina, 2014 The aim of this study was to compile and analyse available historical information on echinoderms in the southwestern Atlantic Ocean in order to make a synthesis of present taxonomical knowledge, to identify patterns of geographical distribution of ...

Symbiotic interactions on middle Cambrian echinoderms reveal the oldest parasitism on deuterostomes [PDF]
Scientific ReportsBiotic interactions are considered as major drivers of evolutionary changes, but their identification in the fossil record is extremely rare and controversial.

Environmental Drivers of Mesophotic Echinoderm Assemblages of the Southeastern Pacific Ocean
Frontiers in Marine Science, 2021 Mesophotic ecosystems (50–400 m depth) of the southeastern Pacific have rarely been studied because of the logistical challenges in sampling across this remote zone. This study assessed how oxygen concentrations and other environmental predictors explain

Symbiotic Life of Echinoderm Larvae
Frontiers in Ecology and Evolution, 2020 Echinoderm larvae have served as a fundamental system for understanding development and life history evolution over much of the last century. In the last few decades, our understanding of echinoderm larvae has expanded to the microbiota that they ...

Gene regulation of adult skeletogenesis in starfish and modifications during gene network co-option
Scientific Reports, 2021 The larval skeleton of the echinoderm is believed to have been acquired through co-option of a pre-existing gene regulatory network (GRN); that is, the mechanism for adult skeleton formation in the echinoderm was deployed in early embryogenesis during ...

EvoDevo, 2023 Background Cadherins are calcium-dependent transmembrane cell–cell adhesion proteins that are essential for metazoan development. They consist of three subfamilies: classical cadherins, which bind catenin, protocadherins, which contain 6–7 calcium ...

Draft Genome of the Sea Cucumber Holothuria glaberrima, a Model for the Study of Regeneration
Frontiers in Marine Science, 2021 Regeneration is one of the most fascinating and yet least understood biological processes. Echinoderms, one of the closest related invertebrate groups to humans, can contribute to our understanding of the genetic basis of regenerative processes.
