These are moon snail egg cases, not pieces of rubber that someone littered. Moon snails use sand and mucus to make the pliable cases. The eggs hang out in the case for a couple of months, then break free and become free-swimming larvae for a while before they settle down and become fully-realized moon snails. We know some humans who've followed a similar trajectory.
