the lateral line of a fish is a sensory organ,picking up vibration in the water,alerting fish to danger or prey.
They are replaced. The old lateral field is taken out, new lines and gravel is are put down and covered.
No.
They are straight lines that form the sides of a polygon.
Yes, many due in their larval form.
penguins,bears,polor bears,chickens and pigs
the lateral lines run along both sides of their body. they detect movement and vibration in the surrounding water. they are also sensitive to light and smell.
Yes halibuts, flounders, tunas, and trouts are all edible.
Fish have lateral lines as vibration sensors.Eyes as visual sensors.
Humans!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
no
yes
They do not have a lateral line but at least some have a lateral line analogue, the epidermal head lines, that are compromised of mechanosensory hair cells and detect water displacement (Budelmann & Bleckmann 1988, J Comp Physiol A)
