Extinct Crocodiles Spotted in Thailand After Decades

After decades of no sightings, endangered false gharials have returned to Thailand's wild, giving scientists hope that one of the world's rarest crocodiles might survive after all.

A local resident in Narathiwat's Tak Bai district spotted the first one at dusk in late January. The thin-snouted freshwater crocodile, measuring about three meters long, appeared in a canal cutting through the swamp forest.

Wildlife researchers rushed to investigate and found a second false gharial, this one about half the size at 1.5 meters. The discovery marked the first confirmed wild sighting in Thailand in decades.

"Their different sizes indicate that their population may grow in the future," said Sukhee Boonsang, director of the Department of National Parks, Wildlife and Plant Conservation. Researchers had only heard stories and seen old tracks, leading most to assume the species had disappeared from Thailand completely.

False gharials once thrived across Southeast Asia, from southern Thailand to Malaysia and Indonesia's islands. But farmland expansion, dam construction, and illegal hunting devastated their numbers over recent decades.

The species now sits on the International Union for Conservation of Nature's Red List as endangered. Fewer than 2,500 fully grown false gharials exist worldwide.

The Ripple Effect

The sighting does more than add two crocodiles back to Thailand's wildlife count. It proves that protected swamp forests in the country's south remain healthy enough to support species on the brink of extinction.

Local communities will now work alongside researchers to develop conservation plans for the area. The canal where both crocodiles appeared flows from upper swamp forests to the sea, creating a corridor that could support more false gharials if protected.

Scientists will patrol and study the Tak Bai swamp forest ecosystem to understand what helped these ancient reptiles survive when everyone thought they were gone. Their presence suggests other remote waterways might harbor hidden populations waiting to be discovered.

Sometimes the best conservation news comes from species we'd written off finding their own way back.
