Today I want to write about an iconic Australian reptile, the frill-necked lizard.

Here are five interesting facts about them:

  1. These large lizards, grow up to 85 cm long, more than half of this length is their tail.  Males are generally slightly larger than females.
  2. They get their name from their brightly coloured frill that they can make stand up to make themselves look much larger to scare off predators.  If that doesn’t work, they turn around and run away on their back legs until they can find a tree to climb.  Their frill also helps them to regulate their temperatures and are used to display during fights between males at breeding time.
  3. Frill-necked lizards spend most of their time in trees, where they catch insects.  They have excellent camouflage and come in a range of colours to suit their habitat.  Lizards that live in drier climates are orange, red and brown, whilst those that live in wetter forests are more likely to be darker brown or grey.
  4.  At breeding time, the female lays between 6-25 soft-shelled eggs in a shallow burrow in a sunny area.  The temperature controls whether the babies are boys or girls, with very hot or cold conditions resulting in mainly girls, but more balanced temperatures resulting in a more even batch.
  5. Frill-necked lizards are found throughout northern Australia and southern New Guinea.  They are very common throughout their range.

I hope that you found these facts interesting and learned something new.
