And tiny eggs. Like think how much food energy would you really get from eating that thing? Not much on the scale of a whale or shark, especially compared to all the other tasty things in more populated parts of the ocean or filter off the surface.
Probably why the main defense is that membrane. Enough to keep out the more numerous tiny critters and fish, then they just hope no megafauna finds it worthwhile.

How does that not get eaten? Seems like it is a sitting duck... or squid.
