Sea anemones might hold secrets to immortality. Researchers found stem cells in Nematostella vectensis that regenerate endlessly, showing no signs of ageing. Unlocking how they work could help us better understand human ageing

Sea Anemone went down to the aquarium this weekend. #seaanemone #aquarium #seattle #detail #tentacle #nature #naturephotography #photography #ocean #closeup
Before spines or skeletons, there was BMP shuttling. Sea anemones just helped reveal the deep roots of your back. #Evolution #DevelopmentalBiology #SeaAnemone

Solving a marine mystery: How #anemonefish avoid stings from their sea anemone hosts

Anemonefish use #SialicAcid metabolism as Trojan horse to avoid giant #SeaAnemone stinging: Natacha Roux et al. https://bmcbiol.biomedcentral.com/articles/10.1186/s12915-025-02144-8
"anemonefish have evolved to maintain very low levels of sialic acid in their skin mucus to avoid triggering the release of stinging cells in their sea anemone hosts."
The aggregating anemone (#AnthopleuraElegantissima), or clonal anemone, is the most abundant #species of #seaAnemone found on rocky, tide swept shores along the Pacific coast of North America. This #cnidarian hosts #endosymbiotic #algae called #zooxanthellae that contribute substantially to #primaryProductivity in the #intertidalZone. The aggregating anemone has become a model organism for the study of temperate cnidarian-algal symbioses.

La anémona burbuja (Entacmaea quadricolor) recibe su nombre por los engrosamientos de los tentáculos de las colonias de individuos jóvenes cercanas a la superficie. Es la compañera inseparable de 14 especies de peces payaso (Amphiprioninae). 📷Jan (Arny) Messersmith #anemona #seaanemone

2) Orange Sea Pen (Ptilosarcus gurneyi)
3) Egg-yolk Jelly (Phacellophora camtschatica)
