The Northern Tree Snake (scientific name: Dendrelaphis calligastra) is a cool snake found in places like Indonesia, Papua New Guinea, and Australia. It's also known as the Green Tree Snake. This snake is thin and has big eyes. It's not venomous, so it's harmless to people.

Northern Tree Snakes are active during the day. They can grow up to 1.2 meters (about 4 feet) long. Their bodies can be green, brown, or grey. They have a cream or yellow belly, which helps identify them. You can also spot them by a wide, dark stripe that goes across their eyes.

About the Name

The scientific name Dendrelaphis calligastra has a special meaning.

  • Dendrelaphis means 'tree Elaphe'. Elaphe is another type of snake. So, it tells us this snake lives in trees.
  • calligastra means 'beautiful-bellied'. This name fits perfectly because of the snake's pretty cream or yellow belly!

Where They Live

Northern Tree Snakes live in tropical northern Queensland, Australia. You can find them from Paluma to Cooktown and in the eastern part of Cape York Peninsula. They also live in southern Papua New Guinea.

These snakes are very adaptable. They can live in many different places, such as:

  • Rainforests
  • Cities and towns
  • Farm areas
  • Open forests

They love to warm up in the sun. You might see them basking in the leaves of small bushes and trees. They are super fast and can quickly disappear through the tree branches if they feel threatened.

What They Eat

Northern Tree Snakes are carnivores, which means they eat other animals. Their favorite foods include:

  • Frogs
  • Other reptiles
