By studying the rocks that Myophorella lusitanica is found in, and by comparison with Neotrigonia we can deduce some information about how Myophorella lusitanica lived.

Myophorella lusitanica had
These features would have helped reduce the threat from predators and reduce the danger of being broken if washed out of its burrow.
These Mollusca are the only surviving genus of the once diverse and widespread Trigoniacea,
