It looks like the Tethya has grown over the cream coloured sponge

Porifera sp.

With its black operculum and being so far south this might be Nerita melanotragus, I'm not sure

Nerita atramentosa

@Jennyncmg the cream coloured sponge the Tethya is on, is that part of the tethya or a different sponge? The cream coloured one seemed to be growing around/under the Tethya and wasn't present in all the spots I found Tethya.

Porifera sp.
