Italian term or phrase: Mollusco bivalve sessile obbligato
It is part of a text:

"L'ostrica concava viene definita un mollusco bivalve sessile obbligato, in quanto le larve al momento della metamorfosi si cementano con la valva inferiore a substrati di varia natura, rimanendovi tutta la vita. Queste ostriche formano solitamente banchi estesi e numerosi, sia su superfici naturali che artificiali (banchine, massicciate, ecc.)."

Can anyone help me with the term "mollusco bivalve sessile obbligato?"

Thanks!

They were likely excavated by lithophagid bivalves, thus extending the earliest record of obligate bivalve

completely sessile bivalve mollusc


Explanation:
my proposal for sessile obbligato is completely sessile, that's the meaning
Mussels and Clams (Bivalvia) - The Living World of Molluscs
www.molluscs.at › bivalvia
So it is quite easy to stop a muscle from closing its shell, but very hard to open it with the mollusc holding tight from inside. .... Swimming mussels, as well as completely sessile mussels, often have a largely reduced foot.

For some weeks the larvae swim the sea together with other plankton. From the fertilised egg hatches a larva that is called a trochophora, because it bears an equatorial ciliar belt and a terminal ciliar crest. After the first metamorphosis the trochophora transforms into a larval stage, that possesses two ciliated sail-like protrusions and thus is called veliger (sail bearer). As well as the trochophora the veliger is a planktontic larval stage. After a further metamorphosis the veliger changes into a bivalve small juvenile oyster. That clings on a suitable rock with its byssus threads and sticks its shell to he rock with a self produced cement. In their further life the oyster will not leave its place any more.
