Available data do not rule out Ctenophora as the sister group to all other Metazoa. [PDF]
Nat Commun, 2023 Redmond and McLysaght (RM) 1 conclude that the position of Ctenophora as sister to all other animals is unsupported. Here, we contend that this conclusion is not consistent with their analyses.

Flow cytometry methods for targeted isolation of ctenophore cells
Frontiers in Marine Science, 2023 Cell suspension fluidics, such as flow cytometry (FCS) and fluorescence-activated cell sorting (FACS), facilitates the identification and precise separation of individual cells based on phenotype.

Speciation of pelagic zooplankton: Invisible boundaries can drive isolation of oceanic ctenophores
Frontiers in Genetics, 2022 The study of evolution and speciation in non-model systems provides us with an opportunity to expand our understanding of biodiversity in nature. Connectivity studies generally focus on species with obvious boundaries to gene flow, but in open-ocean ...

Transposon-derived transcription factors across metazoans
Frontiers in Cell and Developmental Biology, 2023 Transposable elements (TE) could serve as sources of new transcription factors (TFs) in plants and some other model species, but such evidence is lacking for most animal lineages. Here, we discovered multiple independent co-options of TEs to generate 788

Early animal evolution: a morphologist's view [PDF]
Royal Society Open Science, 2019 Two hypotheses for the early radiation of the metazoans are vividly discussed in recent phylogenomic studies, the ‘Porifera-first’ hypothesis, which places the poriferans as the sister group of all other metazoans, and the ‘Ctenophora-first’ hypothesis ...

The Biodiversity of Peter I Island-The Most Remote Island in the World. [PDF]
Ecol EvolPeter I Island is one of the most isolated and least visited islands on earth; lying within the Antarctic Polar Front but over 420 km from continental Antarctica. Here we assess the biodiversity of the island from both previous records and our own BioBlitz in January 2022.

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux. [PDF]
J Exp Zool B Mol Dev EvolEpithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.

Long Term Copepod Culture Houses a Rich Microbial Eukaryotic Community Including New and Known Symbionts. [PDF]
J Eukaryot MicrobiolABSTRACT Copepods, dominant marine zooplankton, are hosts to microbial eukaryotic symbionts, but the copepod eukaryome remains largely unexplored. We used 18S rRNA gene primers with reduced metazoan amplification to identify microbial eukaryotes in a culture of Calanus finmarchicus (Copepoda).

Maximum depth extensions for Hydrozoa, Tunicata and Ctenophora
Marine Biology, 2023 The observation of singleton or rare species in the deep sea is extremely valuable for gaining a census of biodiversity. At hadal depths (> 6000 m), these records provide a more complete picture of the vertical distribution of fauna.
