Why are there no tigers in Sri Lanka?

Fossil evidence confirms tigers crossed this island thousands of years ago inhabited the island, now show that there are no tigers in Sri Lanka. The absence of the tigers today can be attributed in huge part to the rising seas at the close of the last ice age, which separated them from India by flooding the connecting land bridge.

Key Facts:

Geographical Isolation:

For the first time land bridges connecting them vanished, genetic diversity of the tigers also disappeared at the same time.

Extinction:

With most of the forest they once occupied undergoing habitat changes, this small tiger population dwindled away.

Rise of the Leopard:

Given that much larger felines, like tigers and lions, are now no longer in existence on this island, the Sri Lankan leopard evolved as a successful uncontested apex predator, embracing the ecological niche.
