Dynamic Sinking and Surface‐Area Based Decay Modeling Reduce Estimates of Gelatinous Zooplankton‐Mediated Carbon Export to the Deep Sea

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Gelatinous zooplankton (GZ) have been proposed as a potentially important but largely overlooked contributor to the biological carbon pump. However, estimates of GZ‐derived carbon transfer efficiency to the ocean floor reflect uncertainties in key parameters that govern carbon export, leading to contrasting interpretations of the role of GZ in

Never ending analysis of a century old evolutionary debate: unringing the urmetazoon bell

Frontiers in Ecology and Evolution, 2016
Our understanding of the early evolution of animals will be greatly improved if a final solution can be found to the evolutionary relationships between Porifera, Placozoa, Ctenophora, Cnidaria and Bilateria.

Benthoplanidae, a new family of benthic ctenophores (Platyctenida), based on morphological and genetic data

Journal of Systematics and Evolution, Volume 64, Issue 2, Page 387-400, March 2026.
The benthic ctenophore Benthoplana meteoris (adults left and bottom, planktonic juveniles to the top right), type species for the genus, which in turn is type for the newly erected family: Benthoplanidae (Ctenophora, Platyctenida). Abstract We present a phylogenetic analysis of benthic ctenophores of the order Platyctenida, sampling all but one genus ...

Anthozoan eDNA primer set characterizes Ctenophora and Medusozoa inhabiting mesophotic and deep waters off the Gulf Coast of the southern USA

Frontiers in Marine Science
While gelatinous zooplankton (GZ) constitute a vital component of the marine food web, understanding their biology and ecology has been hindered because traditional collection methods often destroy their fragile bodies.

A study on the biodiversity of benthic invertebrates in the waters of Seogwipo, Jeju Island, Korea

Journal of Asia-Pacific Biodiversity, 2014
The biodiversity of benthic invertebrates in the intertidal and subtidal regions of Gapado, Beomseom, and Munseom islets was surveyed twice in May and September 2013 to study the state of biodiversity in Seogwipo, Jeju Island.

Disentangling the counteracting effects of water content and carbon mass on zooplankton growth [PDF]

, 2016
Zooplankton vary widely in carbon percentage (carbon mass as a percentage of wet mass), but are often described as either gelatinous or non-gelatinous. Here we update datasets of carbon percentage and growth rate to investigate whether carbon percentage ...

The Seasonal Rhythms of Coastal eDNA: Insights Into Biodiversity and Regional Detection Patterns

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Seasonal variation affects environmental DNA (eDNA) detection, yet its influence on species monitoring remains underexplored. This study examines eDNA detection windows across taxa, primers, and regions, finding that most species have short detection periods (1–2 months) that vary with taxonomy and primer choice. These results underscore the importance

The homeodomain complement of the ctenophore Mnemiopsis leidyi suggests that Ctenophora and Porifera diverged prior to the ParaHoxozoa

EvoDevo, 2010
Background The much-debated phylogenetic relationships of the five early branching metazoan lineages (Bilateria, Cnidaria, Ctenophora, Placozoa and Porifera) are of fundamental importance in piecing together events that occurred early in animal evolution.

Environmental Gradients and Ecological Processes Are Main Drivers of Eukaryotic Diversity in the Eastern Red Sea

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Across 266 water column samples, COI eDNA metabarcoding detected 4298 eukaryotic MOTUs spanning 40 phyla in the Eastern Red Sea. Community composition varied strongly across depth and regions, revealing hidden biodiversity patterns and providing a baseline for conservation‐oriented monitoring in a future‐ocean analogue.

Investigating Environmental DNA Variability and Species Detections Through Passive and Active Sampling Across Time: A Case Study From a Hyper‐Diverse Coastal System

Environmental DNA, Volume 8, Issue 1, January–February 2026.
This study compared the ability of active and passive eDNA filtration methods to capture environmental DNA in a marine environment with highly variable eDNA signals. Active sampling detected a greater proportion of fish biodiversity, whereas passive sampling detected a larger proportion of metazoa, with a trend of significant accumulation of numbers of
