Head to the top flight of our Tropical House to find our black tree monitor.

This lizard is endemic to humid forests and mangrove swamps in the Aru Islands, off the coast of New Guinea.

They mainly eat insects, although larger monitors have been known to eat birds and even other lizards. Like other monitors they have long, sharp claws and strong jaws which allow them to hold on to their prey.

Interesting facts!

  • Black Tree Monitors are born in various shades of green, but turn completely black as they reach adulthood.
  • Their total length can reach up to three or three and a half feet, with the tail making up 60-70% of the total length.


Black tree monitors are classed as Vulnerable from loss of habitat due to deforestation within its small, restricted range. They are also popular in the pet trade.
