Morphology

genus + Arca

The phrase denotes a taxonomic label formed compositionally from 'genus' (a biological rank) and 'Arca' (the name of that genus), so its meaning as 'the genus called Arca' is directly derivable from the constituents. This follows standard scientific naming conventions common across languages, making it transparent to a learner who knows both words.

Etymology

Genus Arca gets its name from the Latin word Arca, which means 'box' or 'chest'. The shells of these clams look like small boxes or tiny 'arks', so that picture explains why the group has this name today.
