Crocodilians have pressure-sensitive receptors that detect water movement around them.
Gharials possess sensory adaptations suited for detecting fish movements in flowing rivers. Their eyes and sensory pits allow them to perceive subtle disturbances in water. Even in moderately turbid conditions, lateral motion detection aids in targeting prey. The elongated snout positions eyes forward enough to provide directional accuracy during sideways strikes. This sensory integration is crucial in environments where visibility fluctuates. Efficient prey detection supports high metabolic demands for such a large predator. Without accurate underwater perception, specialization would fail.

River turbidity varies seasonally, especially during monsoon floods. Sensory acuity allows gharials to maintain feeding success despite sediment surges. However, excessive pollution or chronic turbidity from erosion can overwhelm natural adaptation. There is a threshold beyond which detection efficiency declines.
This balance illustrates how evolution fine-tunes predators to historical environmental ranges. Rapid anthropogenic changes can push conditions outside those bounds. The ability to track fish in murky water once conferred resilience. In heavily degraded rivers, even refined senses may not compensate for ecological disruption.
