Zenaspis
Extinct genus of jawless fishes
Zenaspis is an extinct genus of osteostracan jawless fish which existed during the early Devonian period. Due to it being jawless, Zenaspis was probably a bottom feeder. Zenaspis was around 10 inches (25 cm) in length. It had a horseshoe shaped head that probably sheltered a small brain.
