Tail beat synchrony decreases when the posterior lateral line system is ablated. (A) Swimming speed increases when the anterior or posterior lateral line is ablated. (B) Tail beat frequency increases when the lateral line is ablated, especially for fish with the anterior (ant) and posterior (pos) region ablated. (C) Rayleigh R calculation for a fish’s tail excursion relative to its nearest neighbor. R decreases when the lateral line system is ablated. The effects remain when the lateral line is regenerated. Asterisks (*) indicates P < 0.05.
