I would like to have a lateral line.  No particular reason; maybe I’d be less easily startled.

Which fishes don’t have one?  Still looking.  (includes:  gizzard shad; threadfin shad; herring; alewife)

Don’t let your lateral line become infected or degenerate due to water conditions.

Most flatfishes have a lateral line on the eyed side; most of those have one on the blind side too.
