Modelling the early evolution of extracellular matrix from modern Ctenophores and Sponges [PDF]
, 2019 Animals (metazoans) include some of the most complex living organisms on Earth, with regard to their multicellularity, numbers of differentiated cell types, and lifecycles.

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

(Table 1) Variation in chemical composition of Black Sea ctenophores depending on size
, 1991 Data of chemical analysis of Black Sea ctenophore Mnemiopsis leidyi indicates that their body contains on average 5.28% carbon, 3.48% nitrogen, 0.11% phosphorus, and 0.03% silicon on dry weight. Mean ratios of the main biogenic elements in ctenophores is

People and Nature, Volume 8, Issue 6, Page 1957-1973, June 2026.Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey

The phylogenetic position of ctenophores and the origin(s) of nervous systems. [PDF]
, 2015 Ctenophores have traditionally been treated as eumetazoans, but some recent whole genome studies have revived the idea that they are, rather, the sister group to all other metazoans.

Molecular Ecology, Volume 35, Issue 12, June 2026.ABSTRACT Southern right whale (Eubalaena australis; SRW) populations are recovering from the impacts of commercial whaling, however, recovery has been spatially variable, with strong associations between reproduction and prey availability. The diet of SRWs has not been widely examined, and with SRW foraging shifting away from high‐latitude foraging ...

Advanced Science, Volume 13, Issue 28, 18 May 2026.Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Optimising Zooplankton DNA Metabarcoding: Methodological Considerations for Large‐Scale Monitoring
Molecular Ecology Resources, Volume 26, Issue 4, May 2026.ABSTRACT DNA metabarcoding is becoming an increasingly common approach in ecological monitoring of marine and freshwater planktonic communities, yet methodological choices along the metabarcoding workflow and data post‐processing approaches remain highly inconsistent across studies, limiting the ability to track biodiversity trends, detect range shifts,
