|“||An armour-plated fish.||”|
Astraspis was a jawless, armour-plated fish from the Ordovician. It was a primitive type of fish which lacked fins and jaws. It was a cousin of the earlier Haikouichthys and the Silurian Cephalaspis, as well as of modern-day lamprey and hagfish
Physical appearance and biology
Astraspis was a jawless fish. It lacked fins and its only method of movement was with its tail. Because of that and its heavy shell-like armor, Astrapis was a poor swimmer and a bottom-feeder that fed on algae and similar substances. Because of this lifestyle, Astraspis had a large head with small eyes and a large sucking mouth.
In Sea Monsters, Astraspis had a green body and a yellow tail.
