## Notes
Thoses sponges shelter a lot of life. Fish, [Astrophyton muricatum - Giant basket star](Astrophyton%20muricatum%20-%20Giant%20basket%20star.md), [Maguimithrax spinosissimus](Maguimithrax%20spinosissimus%20-%20Channel%20clinging%20crab.md) and other crustaceans, echinoderms... Always interesting to watch in it.
