Male gharials develop the ghara only after reaching sexual maturity.
Gharials require many years, often more than a decade, to reach sexual maturity. During this prolonged juvenile phase, they face predation, habitat instability, and accidental capture in fishing gear. High early mortality means relatively few individuals survive to breeding age. Adult males must also compete for territory and mates, further limiting reproductive success. This delayed maturity slows population recovery even when threats are reduced. Long generation times amplify the impact of adult losses. The species cannot rebound quickly from demographic shocks.

Slow maturation creates demographic bottlenecks. Removing even a handful of adult breeders can suppress recruitment for years. Unlike short-lived species that reproduce rapidly, gharials depend on long-term survival of individuals. Population models show that adult mortality has disproportionate effects.
This life-history strategy evolved under stable river conditions with predictable survival odds. In rapidly changing ecosystems, delayed maturity becomes a vulnerability. Conservation must therefore prioritize adult survival alongside juvenile protection. Each breeding adult represents years of ecological investment.
