Juvenile crocodilians often stay in sheltered habitats before dispersing into larger waterways.
After hatching, juvenile gharials often remain in shallow nursery zones along riverbanks. These areas provide warmer water and relative protection from larger aquatic predators. Grouping behavior may dilute individual predation risk. However, shallow zones are also more susceptible to human disturbance and water-level fluctuation. Sudden releases from dams can sweep juveniles downstream unexpectedly. The nursery stage is therefore both protective and precarious. Survival during this early period determines future breeding potential.

Shallow nurseries act as transitional habitats between egg and open river life. They concentrate vulnerable juveniles in limited areas. Disturbance in these zones can eliminate entire cohorts simultaneously. Because early mortality is already high, additional losses significantly impact recruitment.
Protecting nursery habitats requires coordinated river management during breeding seasons. Controlled water releases and reduced human intrusion can improve survival odds. The presence of grouped hatchlings along a sandbank represents the next generation of a lineage stretching back millions of years. Their fragility underscores how narrow the margin for recovery remains.
