This sense is common in aquatic animals, the most cited example being the lateral line system, the array of hydrodynamic receptors found in fish and aquatic amphibians.

Sensory sulci, grooves in the skull that held a lateral line system in life, run across the lacrimal bone but are not angled sharply as in other temnospondyls.
23.
In a 2001 study, researchers demonstrated that the lateral line system was necessary to detect vibrations made by prey, and to orient towards the source to begin predatory action.
24.
When a fish moves, it creates disturbances in the water that could be detected by the lateral line system, potentially interfering with the detection of other biologically relevant signals.
25.
Fish use their lateral line system to follow the vortices produced by fleeing prey, and the oscillating movements of the spoon lure can be a good way to imitate these.
26.
They lost the lateral line system, a network of canals along the skull and jaw that are sensitive to vibration, which does not work outside of an aquatic environment.
27.
Gulper eels are also unusual that the ampullae of the lateral line system projects from the body, rather than being contained in a narrow groove; this may increase its sensitivity.
28.
Their lateral line system is highly developed; the pores run the length of the fish's body, lending it a sort of " sixth sense " by detecting nearby vibrations.
29.
The pumpkinseed has the ability to anticipate approaching predators ( or prey ) via a lateral line system, allowing it to detect changes or movements in the water using different mechanical receptors.
30.
The lateral line system was elaborated on the skull and pectoral girdle-in " Strepsodus " the main trunk lateral line also had several subsidiary lines running parallel to it.
