Well, I Think The Tail.
lateral line is a line on the fish body that function to detect vibrations in water
A lateral line system is an organ in the sensory system that allows fish to sense objects and organisms nearby them through vibrations in the water.
The lateral line provides a fish's sense of hearing and orientation. it contains a complex system of receptors that convert mechanical disturbances or submarine vibrations into nerve impulses. Essentially, it is a fish's underwater ears.
When you tap on the glass of the tank, they feel it. Hope this helps!
Fish do not have tympanic membranes. They sense sounds and vibrations with the lateral line.
worms,fish,snakes,crocodiles and sharks can only hear vibrations
They are pretty much the same thing. They both sense vibrations in the water which sends a message to the brain and the fish or frog can get to safety.
Although I can not say authoritatively, I can however say that fish can not "hear" as we do but instead sense vibrations with their swim bladder. Some fish, particularly fresh water Amazonian fish, sense the vibrations from thunder storms which act as a signal to spawn. Bass frequencies in music can imitate this. One would assume that their respiration rate would increase as a result of the urge to spawn.

Touch and the lateral line system are closely related. Most fish have a well-developed sense of touch. Nerve endings throughout the skin react to the slightest pressure and change of temperature. The lateral line system senses changes in the movement of water. It consists mainly of a series of tiny canals under the skin. A main canal runs along each side of the trunk. Branches of these two canals extend onto the head. A fish senses the flow of water around it as a series of vibrations. The vibrations enter the lateral line through pores and activate certain sensitive areas in the line. If the flow of water around a fish changes, the pattern of vibrations sensed through the lateral line also changes. Nerves relay this information to the brain. Changes in the pattern of vibrations may warn a fish of approaching danger or indicate the location of objects outside its range of vision.

It depends on the fish.A average fishes adaptations are these:Its gills let it breathe underwater.Sensitive areas can detect food by smelling over long distances.Streamlined body shape cuts through the water.Fins to help it move and balance.The body picks up vibrations in the water which helps the fish avoiding danger.
