Genetic variation in the brooding brittle-star: a global hybrid polyploid complex? [PDF]

Royal Society Open Science
The widespread and abundant brooding brittle-star (Amphipholis squamata) is a simultaneous hermaphrodite with a complex mitochondrial phylogeography of multiple divergent overlapping mtDNA lineages, high levels of inbreeding or clonality and unusual ...

Antero-posterior patterning in the brittle star Amphipholis squamata and the evolution of echinoderm body plans [PDF]

EvoDevo
Although 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.

An evo-devo perspective on the regeneration patterns of continuous arm structures in stellate echinoderms

The European Zoological Journal, 2022
Regeneration is a post-embryonic developmental process common in Metazoa, which, despite obvious taxa-specific differences, can often share common principles and patterns.

Macrofaunal Communities Associated with Ecklonia radiata Holdfast Along the Southeast Coast of South Africa

Diversity
Kelp forests are recognized as biodiversity hotspots and ecosystem engineers, while the macroinvertebrates linked with their holdfasts serve as markers of pollution and ecological and environmental change.
