Mugger crocodiles have significantly broader snouts adapted for crushing larger prey.
In parts of India and Nepal, gharials coexist with mugger crocodiles, which possess broader, stronger jaws. While gharials specialize in fish, muggers are opportunistic predators capable of taking mammals and birds. This dietary difference reduces direct competition but does not eliminate territorial overlap. In degraded habitats with limited fish, competitive pressures can intensify. The gharial’s narrow snout prevents it from shifting prey type easily. Ecological partitioning works only when resources remain abundant. As fish populations decline, the balance becomes unstable.

Coexistence between two large crocodilians depends on precise niche separation. The gharial evolved a feeding apparatus that minimizes overlap. However, human-driven resource depletion compresses ecological space. When fish stocks drop, gharials cannot pivot to terrestrial prey the way muggers can. Competitive asymmetry increases vulnerability.
This dynamic illustrates how specialization narrows survival pathways under stress. In intact ecosystems, diversity enhances stability. In degraded systems, specialists lose ground first. The gharial’s evolutionary gamble on fish abundance leaves it exposed when river productivity falters. Competition becomes another pressure layered onto habitat loss.
