To add to the problems for the evolutionists, this sponge has a symbiotic relationship with algae:

Taking inspiration from the age of telecommunications, Italian scientists recently discovered the secret of the symbionts. It turns out that some sponges have a system of fiber optics that allows them to gather what little light reaches their murky depths and to direct it to the algae.

When evolutionists can prove to me that needing a million dollars results in a million dollars being deposited in my bank account, I will start believing in evolution.

Yes the sponge "Rossella racovitzae" has that relationship, and the sponge mentioned here, "Euplectella aspergillum" has a relationship with shrimp. Sprinkler from the Phillipines

Sponges like our treasure have an interesting commensal relationship with some species of shrimp. Pairs of shrimp penetrate the sponge skeleton and upon growing are unable to escape. They spend their entire lives in this "sponge prison". In olden Japan, our treasure was frequently offered as a wedding present to symbolize the idea "until death do us part".
