This study shows that in Nematostella vectensis, nervous system ablation leads to ectopic head regeneration in head fragments, suggesting the nervous system provides positional information to suppress head regeneration in foot fragments.

This study examines how heat stress affects the development and photosymbiosis of Cassiopea jellyfish, finding reduced chlorophyll in algae, delayed metamorphosis, and abnormal ephyra morphology.

This study examines how two nudibranch species interact with scyphozoan polyps, finding that Caloria militaris consumes them and uses nematocysts for defense, while Flabellina affinis avoids them.

The paper identifies conserved matrisomal networks in sea anemones that coordinate life history transitions through proteomic and transcriptomic analysis.

This study characterizes the nervous system of Hydra vulgaris using scRNA-seq, identifying 15 neuron subtypes, mapping their spatial distribution, and exploring regulatory mechanisms through ATAC-seq and trajectory inference.

This paper introduces a predictive framework combining hydrodynamic simulations and population modeling to forecast jellyfish blooms, focusing on moon jellyfish in the Baltic Sea.

This study examines intercellular bridges in Hydra vulgaris, identifying conserved components and revealing their evolutionary significance in cellular connectivity and coordination.

This study investigates the mechanism of eudoxid release in siphonophores, showing it involves muscle evolution and colony modification, leading to an individual-like dispersal stage that contributes to ecological success.

This study identifies new neuropeptides in Hydra using a custom pipeline, revealing a non-amidated regulator of muscle contraction and highlighting neuropeptide diversity and evolutionary adaptability.

The paper identifies bacterial taxa in Cassiopea jellyfish from the Florida Keys, finding they share major taxa with coral microbiomes.

This study shows that Aiptasia oral regeneration is faster in symbiotic anemones, suggesting symbiont-derived photosynthates support regeneration.

The paper compares gene expression in convergent jellyfish eyes, finding mostly lineage-specific expression but shared conserved vision genes across species.

The paper identifies genes involved in nematocyst sequestration in nudibranchs and shows some genes are uniquely expressed in sequestering tissues while others show reduced expression.

The paper studies neural circuit self-assembly in Hydra embryos, showing environmental factors influence neural development and suggesting universal nervous system architecture.

The paper identifies secretory cell types in placozoans involved in feeding, immunity, and behavior regulation using single-cell transcriptomics and imaging techniques.

The paper investigates the mechanical pumping efficiency of sponge choanocyte chambers by combining imaging and computational models, finding that their spherical shape and outlet angle optimize flow.

The paper sequenced transcriptomes of six sea anemone species to identify toxin gene complements and analyze their evolutionary distribution across 26 species.

This study characterizes the venom of Eunicella singularis using proteo-transcriptomic methods, revealing novel toxin folds and evolutionary insights into Octocorallia venoms.

This study simulates the feeding and respiration of early Cambrian cnidarian polyps using CFD to show how muscle contractions drive water flow, supporting hypotheses about ancestral medusozoan behavior.

The paper shows that diet-induced changes in the microbiota can cause dysbiosis and disease in Hydra, supporting the overfeeding hypothesis.

This paper investigates how anemonefish avoid triggering sea anemone nematocysts by reducing sialic acid levels in their mucus, suggesting a Trojan horse mechanism for symbiosis.
