How does the lateral line help a pike hunt?

The lateral line reads pressure waves and water displacement, and in pike it is unusually well developed — including rows of large sensory pores across the underside of the lower jaw, right where an upward ambush strike needs its final targeting data. Vision finds and ranges the prey; the lateral line times and corrects the last split second of the lunge, and keeps working when silt or twilight takes the eyes offline. Blinded pike have been documented surviving and feeding for years on lateral-line information alone — it is a full backup fire-control system, not a garnish.
