Hatchlings communicate from inside the egg with vocalizations that alert the mother.
Female gharials select elevated sandbanks to construct deep nests for their clutches, which may contain up to 60 eggs. During incubation, they remain near the nesting site to deter predators such as monitor lizards and jackals. Unlike some crocodilians, they do not carry hatchlings in their mouths due to their narrow snouts. Instead, they guard the immediate vicinity and respond to hatchling calls once emergence begins. The investment of energy and risk during this period is substantial. A failed nest represents the loss of an entire reproductive season. Protective behavior is therefore critical despite environmental instability.

Guarding behavior increases survival odds but cannot prevent flooding or human disturbance. Females must balance vigilance with thermoregulation and feeding. Prolonged guarding in degraded habitats increases stress and exposure to danger. If sandbanks erode or are mined, protective instincts cannot compensate for habitat loss.
Maternal defense in such a large reptile challenges outdated assumptions about crocodilian behavior. Complex reproductive investment underscores the species’ vulnerability to rapid environmental shifts. Conservation efforts often involve protecting nesting beaches to reduce disturbance. Each safeguarded nest becomes a strategic victory against extinction pressure.
