[4] Myochama exhibit cementation where one valve is fixed to some hard substrate – similarly as oysters.

In Myochama, it is the right valve that gets cemented, typically to the posterior region of shells of large infaunal bivalves.

In Myochama anomioides, this happens when the shell is few millimeters in height (range 1.2–3.9 mm (0.05–0.15 in)).

[4] Typical substrata for attachment include shells of Neotrigonia, Venericardia, and Glycymeris.

Individuals that attach themselves to living objects tend to do so at smaller sizes than those attaching to inanimate objects (e.g., dead shells, rocks).
