Monika,
 
I always thought the pallidula was the one that attached the sponge to
its apex and not the other way around.  Now that I think about it, I
guess it makes sense for a sponge to grow on an pallidula apex but I am
not sure I can envision a full sized sponge spanning two shells and
attaching to each.  Very bizarre.  After the earlier comments about red
tide, I think this may have happened after both shells succumbed to
something and happened to be in the right (or wrong) place at the right
time.
