Could anyone identify this algae species??? I need the species level!

Hello everyone,
I trying to find out which species is this algae. It's in New Caledonia, in shallow waters.
Found in sandy bank and also nested in acropora branches.
It definitly looks like a Codium, but if it is the case, I can't find the species.
It has dichotomous branches and numerous perforations all along the membrane.
If anyone could help me identify this species that would be great.
Thanks ahead!!!

It almost looks like it's calcareous, which, if this is so, it's not Codium sp. Also, most of the Codium I know of, or have ever kept, tends to be a temperate water macro.

Yeah you are probably right, it might not be Codium.
If it can help ere the water temperature varies between 22-28°C.

looks more like a sponge to me, going by all the pores... just a thought.

Thanks for the hint. I finally found out what it is.
It's Ceratodyction spongiosum, a symbiose between a sponge and a red algae.
Case closed! thanks for your help!
