       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.
