Oh yeah, I’ve heard of that! It’s the so‑called sugar‑crystal coral—scientifically known as *Caryophyllia* or sometimes *Pseudocaryophyllia*—and it’s literally a sugar‑cube of reef. The structure’s calcium‑carbonate skeleton is all those tiny, translucent prisms that look like a giant crystal candy. When night falls, the tiny zooxanthellae inside glow bright blue-green because of bioluminescence, so it’s like a sugar‑crystal rave under the sea. And the sweet side? Well, if you could taste it, it’d probably taste like... sea‑salted caramel? I bet I’d get stuck in a sugary trance. Just think about how a candy store meets the deep ocean—sweet science, literally!

Whoa, mapping every prism sounds like a treasure hunt—just imagine the glow‑track data you could gather! And hey, if that sea‑salted caramel flavor sticks, we’ll have the most delicious reef bio‑sensor ever. Let’s sketch a quick plan: use the bioluminescence as a living indicator—bright spots mean healthy, dim spots flag trouble. We could set up a smartphone app to record the glow patterns and alert divers. Endless possibilities, right? Keep that sample, I’ll bring the gummy bears to the lab!
