blureef conosce tutte e 2000 le specie?
lo sai che molte ofiure vivono all interno di coralli vivi?

e la cosa ti dovrebbe far riflettere...
leggi qua:
Brittle Stars & Serpent Stars (Class Ophiuroidea): There are quite a few ophiuroids that live on various corals. My understanding is that relationships are generally commensal, with the ophiuroid living in or around the coral (and/or sometimes sponges). Both in tropical shallow-water and deep-sea habitats. Examples include:
* The six rayed Ophiothela danae from tropical shallow-water habitats
* Several deep-sea "serpent stars"(Phrynophiurida) i.e., those with big fleshy arms that split into massively branched arms such as this that often live on octocoral hosts.
*The Ophiacanthidae-a weird but diverse group of globally distributed spiny brittle stars). Shown here co-occurring with some deep-sea coral.
Ophiuroid-octocoral relationships are quite interesting. And various aspects of this research are being studied, including
systematic relationships
sublethal predation
and other aspects of feeding ecology and reproduction.
Perhaps though, one of the most significant relationship between echinoderms and corals is that several echinoderms EAT coral!!
preso da qui mo non so se č scientifico 
pure io l inglese non č che lo mastico molto ...pero mi sembra di capire che qualche possibilitā ci sia...

Una volta mi fu detto che le ofiure verdi o molto colorate rischiavano
di attaccare i coralli......
