Diving with a Squid Egg Mass

We encountered this in the Philippines, off Ticao Island. No one in our party could identify it (even the divemaster hadn’t seen one before), so we turned to the Internet for help. Reddit user RunningWhale initially identified it as a Pyrosome, but a couple YouTube commenters, below, suggested that it was an egg mass from a diamond-shaped squid. That seems like the most likely explanation at this point. More about squid egg masses:
