Which sense organ of a terrestrial amphibian resembles the fish’s lateral line in function?

The fish's lateral line is used in a multiplicity of ways, in a sensory capacity.  The lateral line in fish is used to detect direction, depth, water temperature, currents, schooling patterns, and motions associated with predator fish.  The lateral line accomplishes this by use of a group of canals either on the skin or just beneath the skin.  Amphibians have ears, just behind the eyes, that take over this function for them.  The mechanic device that achieves this detection of vibration is hairs that exist within these canal areas.  The hair cell is the same type of cell that exists within vertebrate ears.  In amphibians, tadpoles lose their lateral line as they develop into adult frogs, but the hair-like structures present in their inner ears help fulfill the same function of the lateral line.  Frogs are able to detect motion and current changes when submerged in water with the use of electroreceptive cells.  The presence of the hair-like cells in these internal structures help fish, amphibians, and larger scale vertebrates process incoming stimuli from the environment they exist in.
