Nur mit der Wirbelstruktur der Elasmobranchier hat diese Struktur einige Ähnlichkeit. Die Schuppen von Acanthodes besitzen keine Pulpa und es tritt kein Gefäßkanal in den Basalteil der Schuppe ein. Die Schuppen bestehen nur aus Dentin. Sie schließen sich zu einem geschlossenen Panzer aus kleinen, regelmäßigen, quadratischen Plättchen zusammen. Die Flossenstacheln tragen keine Schmelz- schicht.
