In Depth
Sacabambaspis was an early jawless fish, but one that seems to have had a lateral line. A lateral line is a series of sensory organs that allow the fish to detect the movement of other organisms around them, and is seen in modern fish. Sacabambaspis was probably similar to other jawless fish such as Arandaspis and Astraspis.
