Morphology

Centriscidae = Centriscus (opaque) = centriscus + idae

The suffix '-idae' is a specialist taxonomic marker (family) and is not transparently meaningful to an average B1 learner.

Etymology

Centriscidae comes from a Greek word kentriskos meaning 'small sharp point'. It shares the same root as the word center, which originally meant a 'point'. That fits these fish because their long, tube-like snouts make them look like thin spikes when they swim head down, so the name reminds us of their pointed shape.
