On top of the cuttlefish eggs are those structres attached, which look like eggs. Can anybody tell me what they are? And who did lay them? Thank you, Boris
These egg capsules were probably deposited by a species of Nassarius. They are similar to those of the Netted dog whelk N. reticulatus, but with a more rough surface.
I agree with Godfried. They are egg capsules of gastropod, probably Nassarius sp. In the photo attached you can see a lay of Nasarius obsoletus and this lay is very similar to what you have found.
The species may be found in this publication

Thank you very much Godfried, Antoni and Jorge.
Look at what I did find today on the sepia eggs. Could it be Nassarius mutabilis ?
Dear Boris,
for your information: In the western Adriatic in spring artisanal fishers use pots to catch Sepia officinalis that come nearshore on sandy bottoms without vegetation for spawning. They put inside branches of Laurus nobilis to attrach cuttlefish, that attaches its egg on the branches .
Nassarius mutabilis, abundant on these coastal sands spawns in the same period and attaches its capsules, (your photo), on the leaves of Laurus. This is the first time I see the capsules on cuttlefish eggs.
