This construction is interesting, the [Porites sp.](Porites%20sp..md) coral has grown on a sponge and the valonia made it in the middle of this mess.*  *[112 - 2023-02-27 - Pointe Lamarre - Saint Pierre - Martinique](112%20-%202023-02-27%20-%20Pointe%20Lamarre%20-%20Saint%20Pierre%20-%20Martinique.md) - I don't know if the white spots are made by the algae or if it's another animal/vegetal that is using it as a substrate, like the [Electra posidoniae](https://doris.ffessm.fr/Especes/Electra-posidoniae-Bryozoaire-de-la-posidonie-1701) or [Chorizopora brongniartii](https://doris.ffessm.fr/Especes/Chorizopora-brongniartii-Chorizopore-de-Brongniart-1685/(rOffset)/0) bryozoans on [Posidonia oceanica](https://doris.ffessm.fr/Especes/Posidonia-oceanica-Posidonie-265). The best match seems to be [Pneophyllum spp.](https://en.wikipedia.org/wiki/Pneophyllum_cetinaensis), a red unicellular epibiont algae. * ## Notes Curious thing as it shine like metal underwater and is very spheric. I thought at first that it was an animal, like a crustacea or a human related thing, but no, it's an [Algae](Algae.md)! ## References - https://en.wikipedia.org/wiki/Valonia_ventricosa - https://doris.ffessm.fr/Especes/Valonia-ventricosa-Valonie-perle-1279 (fr)
