A Crocodilian Built for One Thing, Destroyed by Everything Else
The gharial's jaw is so narrow it cannot eat anything larger than a fish. Gavialis gangeticus evolved that way over millions of years, a specialist so refined it cannot pivot. That specialisation is also why it collapsed so fast when India's rivers did. When fish populations dropped, when sandbanks were mined, when water levels became unpredictable, the gharial had no fallback. It couldn't switch prey. It couldn't nest on degraded banks. It simply stopped reproducing.
