Either a sponge or a colonial tunicate, but yeah, the flash is pretty blinding and a pic without it may help us tell which.

colonial tunicates are typically very uniform, with all of the in-current siphons being roughly the same size and shape and being distributed very uniformly as well; sponges tend to be less uniform and more haphazard with their in-current siphons;
