Fun Facts

  • With their armour of horns and spines and colouration that matches sand and rocks, giant horned lizards blend in well with their natural environment.

  • When threatened by predators, giant horned lizards may squirt a stream of blood out of their eye sockets. This sudden attack with foul tasting blood can repel the predators.
