I have just had from a fisherman twelve specimens of Argonauta trawled at 450m on mud bottoms in the Jonian Sea (Central Mediterranean). I think that when the egg case is discarded it slowly falls on the bottom like the shell of many other pelagic shells (Atlanta, Peracle, Limacina, Carinaria, etc. etc.), so it may well be trawled.
