Advanced Science, Volume 13, Issue 41, 22 July 2026.We uncover a large variety of putative inhibitory ligand‐gated ion channels (LGICs) in the phylum Cnidaria, the sister group to all bilaterian animals. Phylogenetic analysis suggests a complex evolutionary history of inhibitory LGICs with diverse neurotransmitter ligands.

BMC Biology, 2018 Background Multiple RNA samples are frequently processed together and often mixed before multiplex sequencing in the same sequencing run. While different samples can be separated post sequencing using sample barcodes, the possibility of cross ...

Evaluating 18S Phylogenetic Placement Accuracy to Uncover Hidden Diversity in Non‐Bilaterian Animals
Environmental DNA, Volume 8, Issue 4, July‐August 2026.We assembled the largest curated non‐bilaterian 18S reference dataset and demonstrate that barcode choice strongly influences phylogenetic placement accuracy. Full‐length 18S provides the most robust framework for biodiversity discovery, recovering previously unknown non‐bilaterian lineages, whereas V9 should be interpreted with caution. ABSTRACT Small

Extensive mitochondrial gene rearrangements in Ctenophora: insights from benthic Platyctenida
BMC Evolutionary Biology, 2018 Background Complete mitochondrial (mt) genomes have been sequenced for thousands of animals and represent a molecule of choice for many evolutionary studies. Nevertheless, some animal groups have remained under-sampled.

First records of two lobate comb-jellies (Ctenophora) from the Pakistani coast [PDF]
Check List, 2015 The knowledge on the comb-jellies faunistics along the southern Asian coast is very scarce. For some countries such as Pakistan there are no previous formal records of ctenophores. This study is a first survey to the group diversity along Pakistani coast,

Reproduction and Development in Calcareous Sponges: A Panorama of the Last Two Centuries
Molecular Reproduction and Development, Volume 93, Issue 7, July 2026.ABSTRACT Nearly 200 years ago, scientists began examining reproductive cells in calcareous sponges (Calcarea, Porifera). Since then, 238 studies have been published, encompassing descriptions of gametes and embryos (including ultrastructural studies), life history, asexual reproduction, regeneration, and molecular aspects of development.

A late-surviving stem-ctenophore from the Late Devonian of Miguasha (Canada)
Scientific Reports, 2021 Like other soft-bodied organisms, ctenophores (comb jellies) produce fossils only under exceptional taphonomic conditions. Here, we present the first record of a Late Devonian ctenophore from the Escuminac Formation from Miguasha in eastern Canada. Based

Water Environment Research, Volume 98, Issue 7, July 2026.Urban stormwater ponds support pollution‐tolerant diatom and macroinvertebrate assemblages that are shaped more by local water quality, contaminants, and habitat features than by surrounding land use. Integrating biological monitoring can better inform stormwater management and urban biodiversity planning.

New genomic data and analyses challenge the traditional vision of animal epithelium evolution
BMC Genomics, 2018 Background The emergence of epithelia was the foundation of metazoan expansion. Epithelial tissues are a hallmark of metazoans deeply rooted in the evolution of their complex developmental morphogenesis processes.
