*[135 - 2023-07-22 - Grottes fauconières - Saint Cyr - France](135%20-%202023-07-22%20-%20Grottes%20fauconières%20-%20Saint%20Cyr%20-%20France.md) - I really was impressed by this sponge. The color is awesome. With [Parazoanthus axinellae - Yellow encrusting anemone](Parazoanthus%20axinellae%20-%20Yellow%20encrusting%20anemone.md) around, and a very small ophiuridea, that I can't identify. I can't identify the pink sponge under it neither.*
## Notes
It's not a typical sponge, not just because of its fluorescent yellow color, but because it's made out of limestone.
There's two other variations of this species, that can be found in caraibean sea, called Car-sp1 and Car-sp2.
