Complete mitochondrial genome of the feather star Cenometra bella (Hartlaub, 1890) (Crinoidea: Colobometridae)

open access: yesMitochondrial DNA. Part B. Resources, 2022
The complete mitochondrial genome of the feather star Cenometra bella was sequenced in this study. The mitogenome is 15,872 bp in length, with 13 PCGs, 22 tRNA, and two rRNA, and nucleotide composition was as follows: 24.38% A, 47.79% T, 11.16% C, and 16.

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 521-544, July 2026.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

Los equinodermos (Cystoidea. Homalozoa. Stelleroidea. Crinoidea) del Paleozoico Inferior de los Montes de Toledo y Sierra Morena (España)

open access: yesEstudios Geologicos, 1984
Se confirma la presencia de los cistideos Codlocystis y Phlyctocystis en el Llandeilo de España, junto a un Diploporito indeterminado que quizá corresponda a un nuevo género.

The complete mitochondrial genome of the starfish Coscinasterias acutispina Stimpson, 1862 (Echinodermata, Forcipulatida) from the East China Sea

open access: yesMitochondrial DNA. Part B. Resources, 2022
In this study, we determined the first complete mitochondrial genome sequence of Coscinasterias acutispina Stimpson, 1862. The mitogenome was 16,186 bp in length and contained 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes ...

Biogeography of intertidal invertebrates is influenced by latitude along the west coast of Australia

open access: yesEcography, Volume 2026, Issue 6, June 2026.
Along the west coast of Australia, intertidal rock platforms support high invertebrate diversities that provide vital ecosystem services, yet patterns in diversity are not well understood. Here, we document and examine the invertebrate assemblages on intertidal rock platforms in Western Australia and delineate ecoregions according to assemblage ...

Plated Cambrian bilaterians reveal the earliest stages of echinoderm evolution [PDF]

open access: yes, 2012
Echinoderms are unique in being pentaradiate, having diverged from the ancestral bilaterian body plan more radically than any other animal phylum. This transformation arises during ontogeny, as echinoderm larvae are initially bilateral, then pass through

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.
