[Coral-List] Halichondria okadai -Japanese sponge on reefs?

[Stephanie Wear]

Hello Listers!
I am trying to determine if the sponge: Halichondria okadai is a coral reef
sponge ­ that is, does it live on or very near coral reefs? I have been
trying to cross reference its distribution with coral reef maps in Japan and
just want to be sure. Thanks for any info you can provide on this species.
Cheers-
Stephanie
