Do all fish have a lateral line?

    No, not all fish have ‘lateral lines’.  However, all fish have some sort of neuromasts which help them detect pressure changes in the water.  Lateral lines are neuromasts which can be seen as lines along the fish’s side. Skates, rays and sharks have neuromast canals.  The blind cavefish has neuromasts in lines on it’s head.
