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."

"Scientists at the Okinawa Institute of Science and Technology (OIST) and their international collaborators have discovered that anemonefish have evolved to maintain very low levels of sialic acid in their skin mucus to avoid triggering the release of nematocysts (stinging cells) in their sea anemone hosts.
The researchers found that sea anemones also lack these sugar compounds in their own mucus, likely to avoid stinging themselves".

I printed my rose bubble tip anemone a little anemonefish friend. There two animals have a mutualistic symbiotic relationship and benefit one another!

Clownfish of the day: OK, one more clownfish to share. This time we have tomato clownfish in the beautiful reefs of Apo Island. Wide angle photography is not my specialty, but I really like this reef scene with the clownfish moving through the huge anemone arcing across the surface, giant clam in the foreground, and soft corals in the background.

Scientists reveal new lineages of giant sea anemones in Japan and their surprising associations with anemonefish

Anemonefish are better taxonomists than humans https://www.cell.com/current-biology/fulltext/S0960-9822(23)00990-9

"The scientists discovered that #anemonefish are better at distinguishing different populations of giant #SeaAnemones than humans. Through one or more sensory organs, these #fish identify a particular species of giant sea anemone to make their home and avoid other species."
