A genus of ancient armored fish with prominent spines or ridges on the head.
From Greek 'kephale' (head) + 'akantha' (spine or thorn) + '-us' (Latin nominative singular suffix). This is a scientific genus name following binomial nomenclature rules.
Cephalacanthus represents a fascinating dead-end in evolution—these fish thrived for millions of years with their elaborate head armor, then disappeared entirely, leaving no descendants in modern oceans.
