Sponge ID confirmation please

[DangerDave]

Hello

I believe that both of the pics below are of sponges, can anyone confirm? They do seems to have dots that appear to be mouths? This is confusing me, I didn’t thing sponges did, and that’s causing me to second guess my ID as sponges...

Yup to sponge.

The opening is the Osculum.

The top picture is most definitely a sponge, the bottom is a little harder to discern.
