Exactly! :) We discuss the dinoflagellate mucosphere (from Larsson et al) in our study. The problem (or charm!) studying Radiolaria is that they don't reproduce in culture, so much of their biology and ecology is based almost only on field observations.

I was lucky enough in college to see a bioluminescent dinoflagellate bloom on the Florida panhandle.
Just absolutely amazing.
Just absolutely amazing.
If you visit the Maldives, located at an intersection of seas in the Indian Ocean, you might witness the SEA OF STARS.
A glittering spectacle made of microscopic organisms generating their own light, mirroring the twinkling of stars above.

So why does San Diego get a uniform blue glow, while the Maldives get sparkling stars?
*I don't know*.
There's a 2nd species of dinoflagellate, Noctiluca scintillans, that's more common in tropical waters & it could be contributing.
Or it could be local chemistry or biota?
It's gorgeous though.

The blue glow comes from dinoflagellate 'Lingulaulax polyedra' (formerly Lingulodinium polyedra).
These single-celled eukaryotes contain organelles called 'scintillons' that produce enzyme 'luciferase' & substrates needed to produce bioluminescence, similar to fireflies.

By comparing heat-tolerant & heat-sensitive dinoflagellate algae, Tingting Xiang of UC-Riverside will ID genetic switches controlling photosynthesis under thermal stress, providing insights to improve bioenergy crop resilience. 🖥️🧬

Thank you Miguel! Of course a Dinoflagellate is completely different, but a mucosphere could serve the same purpose in attracting and capturing prey for other organisms as well.

Had a one semester job at one once, teaching plant biodiversity. Structured the course along the lines of plant evolution. Gee I had fun quoting Exodus, rivers of blood stuff. “This is a probable example of early documentation of a toxic dinoflagellate red tide” 🤔😁

Always a pleasure to see a Tripos sp. dinoflagellate in one of my samples. I don’t see them too often so when I spot one I do get a little excited!
