Togian Water Monitor

A modern-day dragon of the mangroves, equally at home on land and in the sea.

  • Local name: Biawak
  • Scientific name: Varanus togianus

Varanus togianus are monitor lizards endemic to the Togian Islands, adapted to both forest and mangrove environments. They're opportunistic hunters of invertebrates, insects, and eggs, spending time basking on logs or muddy banks before slipping into water when approached.

Where to see it

Found in mangrove creeks, muddy shorelines, and forest edges on larger Togean islands. They favor areas where mangrove meets open water or mudflats, typically seen during low tide when they bask on exposed logs, roots, or mud banks.

How to spot it

Move slowly and quietly along mangrove edges at low tide. Scan sunlit logs and muddy banks for dark, elongated shapes. They're alert and quick to retreat — watch for sudden movement as they drop into water or disappear into vegetation when they detect you.

Watching responsibly

  • Maintain distance — they can deliver painful bites if cornered or threatened.
  • Never attempt to handle, catch, or corner them against water or vegetation.
  • Don't block their escape routes to water — they rely on quick retreat for safety.
  • Avoid approaching nesting areas or digging sites where females may be laying eggs.
  • No feeding — it alters their natural wariness and hunting behavior.

Conservation

IUCN Least Concern; small range but no major documented threats.
