Morphology
The phrase simply names a taxonomic group: 'family' (a scientific grouping) combined with the proper name 'Rachycentridae' directly signals the family called Rachycentridae. This compositional, label-like structure is standard in scientific nomenclature and is immediately understandable to learners who know both constituents.
Etymology
Family Rachycentridae is like a 'family' with only one member — the fish called the cobia. Scientists use family Rachycentridae to show this group of open-ocean fish contains just that single species.
