Dear David,
It may be your first message, but I hope it's not your last. It's not often we get all this biological information so quickly for a species only a few days old.
The white network in the sponge in the upper photo is not, as you thought, made of siliceous spicules, but is the very characteristic network of spongin fibres found in the dysideid genus Euryspongia. Species of Hypselodoris, and other chromodorids, feed on sponges which lack skeletal spicules. Your observations are very interesting because quite a few of the 'high profiled' species of Hypselodoris feed on Euryspongia. The spiderweb-like tangle of fibres all over your lower photo are part of the sponge colony's remains, showing just how much of the colony these nudibranchs have consumed.
This is a valuable contribution to our knowledge.
Best wishes,
Bill Rudman
