Mitochondrial Genome Reduction and Accelerated Evolution in Planktonic Foraminiferans

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
The mitochondrial genomes of the eukaryotic lineage Retaria (Foraminifera and Radiolaria) show reductions in multiple gene categories, including complex I, transfer RNAs (tRNAs), ribosomal proteins, and ribosomal RNAs. In planktonic foraminifera, this reduction is even more pronounced, with the potential loss of atp and other genes.

Characterization of nAChRs in Nematostella vectensis supports neuronal and non-neuronal roles in the cnidarian–bilaterian common ancestor

EvoDevo, 2019
Background Nicotinic and muscarinic acetylcholine receptors likely evolved in the cnidarian–bilaterian common ancestor. Both receptor families are best known for their role at chemical synapses in bilaterian animals, but they also have described roles as

Metabolic Signatures of Aging and Gametogenesis in Hydra oligactis

Aging Cell, Volume 25, Issue 8, August 2026.
Hydra oligactis undergoes cold‐induced sexual differentiation and aging, culminating in death. GC–MS‐based metabolite profiling revealed signatures of gametogenesis, for example, polyamine accumulation, and of aging, such as loss of cytoprotection and neurotransmitter function, including taurine depletion.

Independent evolution of striated muscles in cnidarians and bilaterians [PDF]

, 2012
Striated muscles are present in bilaterian animals (for example, vertebrates, insects and annelids) and some non-bilaterian eumetazoans (that is, cnidarians and ctenophores).

Global Neuropeptide Annotations From the Genomes and Transcriptomes of Cubozoa, Scyphozoa, Staurozoa (Cnidaria: Medusozoa), and Octocorallia (Cnidaria: Anthozoa)

Frontiers in Endocrinology, 2019
During animal evolution, ancestral Cnidaria and Bilateria diverged more than 600 million years ago. The nervous systems of extant cnidarians are strongly peptidergic.

Deep-sea cnidarians of Northwest Africa: Distribution patterns [PDF]

, 2015
Cnidarians are one of the most relevant phylum in deep-waters, where Scleractinia, Alcyonacea and Antipatharia may build three-dimensional habitats which host some of the most biodiverse and vulnerable marine ecosystems (‘hot-spots’) along the ...

The role of retinoic acid signaling in starfish metamorphosis

EvoDevo, 2018
Background Although retinoic acid (RA) signaling plays a crucial role in the body patterning of chordates, its function in non-chordate invertebrates, other than its mediation of environmental cues triggering metamorphosis in cnidarians, is largely ...
